14.0 Taking Care of your handheld Transceiver

Your transceiver has been designed using the latest in technology

along with high temperature flame retardant plastics. Normal reg-

ular care an attention will increase the longevity of certain compo-

nents.

 Handle your radio with care.

 Do not carry the transceiver by either the antenna or the op-

tional external speaker microphone.

 When the speaker microphone or other accessory is not in

use, keep the speaker microphone accessory jacks covered

by using the supplied flap that is attached to the radio.

 To clean, use a moistened rag with a mild detergent, and with

a nearly dried cloth, clean the case, control knobs, and key-

pad. Never use any chemicals to clean the unit.

 Regularly, wipe the battery contacts with a lint-free cloth to

remove dirt, grease, or any other materials that may prevent a

good electrical connection.

 Never Expose the Radio to direct sunlight, heat or cold for ex-

tended periods of time.

OPERATIONAL INSTRUCTIONS & SAFETY GUIDELINES

RF ENERGY EXPOSURE IS DETERMINED PRIMARILY BY

THE DISTANCE TO, AND THE POWER OF, THE TRANSMIT-

TING DEVICE. In general, RF exposure is minimized when the low-

est possible power is used and transmission time is kept to a minimum

consistent with effective communications and the antenna is at the

furthest possible distance from the body. Users should transmit no

more than 50% of the time and follow the guidelines:

To Transmit and Receive: You must be properly licensed by

the FCC or your governing radio communications authority

to use this radio on the programmed frequencies.

To Transmit, first hold down the MON (Monitor) button if so pro-

grammed for a moment to make sure that the channel is not busy with

other traffic that you may not hear this depending on the TONE that

may be programmed in shared transceivers if the channel is a shared

frequency with other users with different CTCSS/CDS Tones. You may

also look at the received signal strength meter (green light) is off) to

ensure that the channel is clear.

To transmit: Push and hold the Push– to-Talk (PTT) Button; speak in a

normal voice. There is a 1/4 second delay before the radio transmits

as the RF output to the antenna is tuned to the frequency/channel be-

ing used.

To Receive, release the PTT button.

Hand-held Transceiver Operation:

Hold the radio in a vertical position with the radio approximately 1.5 to

2.5 “ away from your lips.

Body Worn Application:

As in most cases whenever using an approved case and body pack for

this transceiver or not, use of this radio with the antenna touching the

body may exceed the FCC RF exposure guidelines.

Antennas & Batteries

Use only Infinity supplied and approved antennas and batteries.

Use of non approved accessories and attachments as well as

user modifications could not only damage the radio and void

warranty, but also may void FCC and CE regulations as well as

exceed RF exposure limits. DO NOT OVERCHARGE BATTER-

IES. Keeping the battery in the charger continually reduces bat-

tery life. Consult Infinity or your Authorized Reseller/ Distributor

if you have any questions.

User Precautions: Safety, Warranty and Use

The following will assist you in fulfilling any warranty obligations.

 Do Not Modify this radio for any reason. Do not disassemble the radio.

Failure to comply may void Warranty and governmental approvals. No

User Serviceable Parts inside. Refer repair to Factory Authorized Per-

sonnel only.

 Do Not Use the transceiver or charge the battery in an explosive envi-

ronment.

 Keep the transceiver out of direct sunlight, DO NOT expose the unit to

extreme heat or cold.

 Keep the transceiver out of dusty or humid areas. IF IMMERSED IN

WATER, TAKE OUT OF WATER AND BLOW AIR ACROSS THE

SPEAKER AND SHAKE ANY WATER THAT MAY BE TRAPPED IN

FRONT OF THE SPEAKER GRILL.

 Do Not Transmit without an approved antenna connected to the trans-

ceiver. Install the battery only after the antenna is connected to the

radio. Fully charge the battery first to condition it.

 Observe common sense when attempting to transmit in areas such as

construction sites, mines, hospitals, hazardous environments, etc..

Turn off your radio before entering any area with a potentially

explosive atmosphere (where the air contains gas, dust), as well as

while taking on fuel, etc.).

 Typically transmit for no longer than 1 minute with a rest period of 4

minutes. Longer transmission times will see the rear side of the radio

heat up.

 If the radio emits smoke or strange odors, turn the radio off, discon-

nect the battery and promptly contact your local authorized Infinity

Dealer or Re-Seller.

About your radio: Infinity radios are sold only through Infinity or Au-

thorized Resellers. The radio is also field programmable using the key-

pad, software, or wired cloning (if enabled by the software); and may

come pre-programmed with either factory defaulted programming or

other User channels. Full function access to the radio and options is

only available if the optional Infinity programming software with the ap-

propriate interface cable has been purchased. The sale and use of

these radios is restricted to licensed users only. User takes the respon-

sibility to comply with FCC and other governmental or local require-

ments. CONDITION OF SALE: The User is familiar with radio opera-

tions, radio configuration and radio terminology. It is important

that the User is aware of and understands hazards common to the op-

eration of any radio transceiver. Thank-you for selecting the K-911 for

your radio communications needs!

13.0 PROGRAMMING VIA SOFTWARE Your radio comes pre-

programmed with some channels for test. The Programming kit comes with a

USB cable, Programming Software and a USB cable driver for WIN XP and

Win7,(Model PG-12). (For Win 8, Order Model PG-13.) PC SKILLS AS WELL

AS FAMILIARITY WITH TWO RADIOS ARE NECESSARY. You will need to

unzip the files provided using a free program called WINRAR from WIN RAR

LABS and is available as a free download from the Internet. When downloading,

just download only the free unzip program. In preparation for programming:

(1) Load (unzip) the USB driver onto the PC. Install the USB driver.

(2) Load (unzip) the Programming Software onto your PC.

(3) Restart the PC.

(4) Connect the supplied USB driver to an available port on the PC

(5) Check with Windows device manager that the USB cable is operating and

seen by the PC

(6) START the programming software by clicking on the K-911 Icon that is on

your desktop, placed automatically by extracting the software from the exe-

cutable file. THE FOLLOWING SCREEN APPEARS:

(7) CLICK ON SETTING; PORT. A POP UP SCREEN WILL APPEAR WITH

THE PORT NUMBER CORRESPONDING TO THE USB CABLE. (example,

COM 5). THEN PRESS OK. IF NO PORT NUMBER APPEARS, CHECK

WINDOWS DEVICE MANAGER TO MAKE SURE THAT THE USB CABLE

DRIVER (PROLIFIC) HAS BEEN SUCCESSFULLY INSTALLED.

(8) WITH RADIO ON AND CABLE CONNECTED, THEN perform a “READ

FROM RADIO, then save the file, NAMING IT AS AN EXAMPLE, “ORIGINAL

FILE”.

(9) THEN make changes as needed, then SAVE THE FILE, EXAMPLE, AS

‘MASTER 1 FEB 2015”, THEN WRITE TO RADIO.

COM 5

12.2 Receive CTCSS/DCS (QT and QDT) functions that have been

programmed by your dealer or your communications specialist will allow

you to hear radio traffic only when the these sub-audible signaling tones

have been heard from another similarly programmed radio by your re-

ceiver. Only then will the radio allow you to receive a transmission of the

same tone. If tone decoding is not used or programmed in the transceiv-

er, then all conversations on the programmed frequency will be heard.

12.2 Radio ANI ID is a feature that transmits a unique ID

number that has been programmed into your radio. This allows all

radios in this group to see each other. Then program each individ-

ual radio with an ANI Code (number that corresponds to the radio

call of the user), with end of transmission selected. Each radio

has a unique number. Using this feature may or may not affect the

receipt of some repeater based ID transmissions and may not

work with all Motorola MDC1200 systems. Test first to evaluate

the situation. Also set up in digital signaling for dPMR digital

mode.

12.3 Receive CTCSS/DCS (QT and QDT) functions that have been

programmed by your dealer or your communications specialist will allow

you to hear radio traffic only when the these sub-audible signaling tones

have been heard from another similarly programmed radio by your re-

ceiver. Only then will the radio allow you to receive a transmission of the

same tone. If tone decoding is not used or programmed in the transceiv-

er, then all conversations on the programmed frequency will be heard.

12.4 Talkaround. This function is enabled by the user in situ-

ations where the user does not want to trip the repeater but have

local ground operation conversations to local responders and not

be heard over the repeater network.

First select your channel. This must be a repeater channel.

PRESS THEN THE ASSIGNED HOT KEY AS PROGRAMMED IN

THE PROGRAMMING SOFTWARE. To cancel and return to nor-

mal repeater operations: Press the HOT KEY button.

USING THE TALKAROUND FUNCTION will see all Radio units

that are in close proximity to your area of operations hear you on

the repeaters output frequency as you are transmitting and receiv-

ing on the repeater output frequency. They also, as well as you,

will hear the repeater. The corresponding CTCSS/DCS tones will

also follow automatically. This is not to be confused with

“Reverse” hot key operation, which simply inverts the TX and

RX frequencies and tones. (See Page 12). Consult your Com-

munications Officer for details.

K-911 Main Product Features at a Glance:

Your transceiver is 2 and 5 tone , DTMF paging receive

and encode capable.

For 2 Tone Paging Radio Operation,

either for Decoding (receive) or Encoding (creating a 2 tone

transmission), you will need to use the

Optional Paging Radio Software, as these functions are not

keypad field programmable.

You will need also to find out and make note of the “A” and

“B” Tones for your paging system, and their spacing as it

applies to your radio system for successful 2 tone decode

(or encode) operation.

HINT: For use with commonly used MOTOROLA Minitor pag-

ing systems, the following settings should be used:

-First delay: 0.5 (length of first tone)

-Second Delay: 0.5 (length of second tone)

-Interval Time: 2.0 (time between tones A & B)

-Long Delay: 5.0 (when creating a page, (Encode mode only),

this is the time that radio waits once PTT is pushed to send out

About dPMR digital Private Mobile Radio 6.25 kHz Technology

Since the beginning of PMR radio, there has been a constant juggl-

ing act between available spectrum and channel size. As filter and

modulation technology has advanced the channel size has progres-

sively reduced, 100 kHz, then 50, followed by 25 and then the 12.5

kHz we have known for the last twenty or so years. Add to that the

current policy of spectrum pricing and it becomes clear that a new

advance was needed to make the most efficient and economical

use of this scarce resource.

Traditionally PMR has always operated with FDMA technology as

that has offered the best flexibility to users. The initial plan for Euro-

pean standardization was based on 2-slot TDMA technology as sev-

eral of the major PMR players have proffered that 6.25 kHz FDMA

was simply not possible. Research by Icom and Kenwood however

showed that 6.25 kHz FDMA was a practical proposition and they

entered into a joint agreement to develop the technology further.

This new digital 6.25 kHz FDMA idea was taken up by ETSI (the

European Telecommunications Standards Institute) and developed

into a European Standard. dPMR became an open, non-proprietary

EU standard and was published under the reference TS 102 490

(License-free) and TS 102 658 (Licensed).

Your K-911 radio operates in Analog as well as in both dPMR digi-

tal conventional and digital trunking modes. To enable backwards

compatibility, they also operate in 25 kHz and 12.5 kHz channel

bandwidths. Backwards compatibility to analog only radios enables

a planned migration path to “digital” with existing radios operating

analog only and new radios operating analog and digital as soon as

industry standards and norms evolve.

Therefore your radio is dPMR ready. Functions etc. are all

software defined by the programming software.

9.3 TOT (Time-out Timer)

The Time-out timer can prevent a User from occupying a certain

channel for an extended period of the time or prevent a charnel being

occupied by a radio that has it’s PTT held down accidently (radio in

back pocket). Once the TOT time has been reached, the 2 way radio

will stop transmitting and a warning tone will be sounded alerting the

user of this. TOT reset. This is the time delay after the PTT key has

been released and the PTT button will return active (normal mode).

9.4 Auto Battery Power Saving

If this function is enabled, 10 seconds after no signal is received or no

User operation is carried out, the radio will be in the power-saving

mode. When any signal is received or any operation is carried out, the

radio can automatically quit this mode. Power-saving modes: 1: 1, 1:

2, 1:4 and off. Setting the power-saving function of a battery can re-

duce the power consumption of the battery.

9.5 Busy Channel Lockout (BCL)

If the busy channel lockout has been activated, transmitter activation

is prohibited on a channel that is busy channel. If one presses the

PTT button to transmit and with the channel occupied, the unit’s

speaker will sound a “busy channel lockout" tone, and where the Us-

er may not activate the transmitter.

Lock Out Settings for flexibility: (i) Carrier wave: If there is a carrier

on the channel, radio transmission (PTT) is inhibited. (ii) Lock out on

Carrier wave + CTCSS/ QT/DQT/DCS: If there is both a carrier

wave on the tuned channel with a valid CTCSS/QT/DQT/DCS match-

ing PL tone, transmission (PTT) is allowed.

8.3.6 Remote kill/remote stun

This is programmed via software, if a radio is lost or stolen, and if the

radio received a remote Kill Code: it will be disabled.

If it received a stun code, it will receive but not transmit.

5.0 About Radio Operations.

5.1 Terminology.

In a wireless Land Mobile Radio (LMR) Communications system, there are

two modes of operation: DIRECT (communicating on the same transmit and

receive frequency between radio users, sometimes called Radio to Radio,

Car to Car, or SIMPLEX); and over a REPEATER (where a portable or mo-

bile radio transmits on one frequency and receives on another).

In DIRECT/SIMPLEX MODE, there may be obstacles such as buildings or

uneven terrain affecting the transmission over long distances of communica-

tions between two or more low power (ex. 5 watt) portable radios. In a RE-

PEATER configuration, a radio receiver and high power radio transmitter

(example 50 to 150 watts) with two antennas is located on a mountain top or

elevated location.

When using a handheld radio the Repeater due to its better elevated loca-

tion and higher output power, it receives much better the low power signal of

the hand held or other radio units. Once received, the transmitter retransmits

simultaneously the received radio transmission from the handheld or mobile

radio on a frequency that differs from the received signal at higher power.

When strategically located on top of a high building or a mountain top, the

Repeater can greatly enhance the performance of a wireless network by al-

lowing communications over distances much greater than would be possible

without it. In this case coupled with higher power, the Repeater “repeats” the

communications from the hand held or mobile unit that it receives, and in-

creases the range due to the higher power and better antenna and location

of this relay station.

TIP: Using “Talkaround” feature: When Teams do not have a simplex

private channel to work with and only have a repeater channel available,

some radios such as this K911 may allow you to preprogram a hot key to set

the repeater channel into TALKAROUND mode. In this setting the repeater

stays the same but radios set to TALKAROUND will transmit and receive on

the repeater’s output. (“A”). This only works if both users are within range of

each other as no repeater is used. In this fashion field units will also hear

the repeater’s transmissions and may respond if needed by turning TALKA-

ROUND off.

5.2 About Sub-Audible QT (Quiet Tones)

(CTCSS) and Digital Sub-Audio (DQT / DCS)

Tones

QT or CTCSS (Continuous Tone-Coded Squelch System is a

circuit found in a two way radio transceiver that is used to reduce

the annoyance of listening to other users on a shared two way

radio system where more than one user group is on the same

channel and frequency, (called co-channel users). Using CTCSS

or QT filters out other users if they are using a different CTCSS/

Qt tones, or no CTCSS. DQT or DCS is called Digital Coded

Squelch, similar to CTCSS.

Example: One may have both the Fire Dept. and EMS on the

same frequency. During standard operations, one may not want

to hear the other. The two-way radio receiver's audio turns on

only in the presence of the correct sub audible tone that only the

radio hears that corresponds to the respective agency’s pro-

grammed sub-tone. Therefore in this application, Fire uses one

sub- tone, EMS another. Conventional radios without CTCSS (or

CTCSS turned off, or seeing the User pressing the MONI button

on the K-911 would hear all transmissions from both groups. The

Firefighters would have to listen to the radio traffic from EMS

while EMS would hear all conversations from Fire.

If the radios are programmed with 2 different CTCSS tones on

two different channels using the same frequency, units from

each group would only hear radios from their own Department

that are programmed to the same CTCSS or DCS code number

of their group. Using this also reduces missed messages and the

distraction of unnecessary radio traffic from the other Agency.

There are many other uses for CTCSS/DCS often called PL

TONES (Motorola term) or Channel Guard. (A GE term).

Prior to programming a radio one therefore needs to mark

down the following:

-Receive Frequency

-Receive Tone (If CSQ is written, there is no tone used)

-Transmit Frequency

-Transmit Tone

-Whether the radio is to operate in narrow or wide band

-The channel alias associated with the particular radio

channel

This information should be available from your communications

officer.

6.0 Basic Transceiver Operation-Quick Guide

To Turn the Transceiver On: With the antenna connected and bat-

tery inserted, rotate the power/volume control knob clockwise. The col-

or LCD screen will come on with “INFINITY” as the defaulted start up

screen. In start up option, Battery Voltage may also appear if selected.

The radio will display the channel number and channel alias for both

banks of the radio, A and B. 128 channels per bank.

Increase or Decrease Volume as needed. If there is no one on frequen-

cy and nothing is heard from the unit’s speaker, you may adjust volume

by pressing the MONITOR button (opening up the squelch), and then

adjusting the volume level as needed. See Page 15, Section 7.1 for

preprogrammed Channel Defaults from the Factory.

Squelch: The transceiver has a preset squelch level which may be

adjusted (in the Squelch set-up/programming mode either in the soft-

ware or by using the front keypad. To do so USING THE RADIO: with

the LCD screen lit and to the lower left hand coroner, the word “MENU”

will be present. Press the [ — ] key immediately below the word

“MENU”. Rotate the channel selector going thought the various menus

that appear until you see “RADIO SET”. Press the [ — ] button below

the word “SELECT” and rotate the channel selector once more until you

see the word “SQL LEVEL” appears on the screen. Press the [ — ]

once more and select the entry. SQL level 9 closes the squelch level

threshold, while SQL level 1 opens up the squelch. Select as desired.

Press [ — ] BACK repeatedly to exit and save.

This should be set to “5” for normal operation.

Transmitting: It is common practice to hold down the MONITOR but-

ton momentarily (Button “SK2”, Page 10), to open up the squelch and

defeat the CTSS/DCS tone that may have been programmed to avoid

transmitting while another station using another CTCSS or DCS tone is

on your radio frequency but not on your tone. If this is the case, you

may also consult the “receive signal bar meter” that also shows relative

receive signal strength. If another station is on frequency you will see

the received signal on this bar graph. Also is there is another station

the GREEN LED on the unit will also light up. If the MONI button would

be pushed, ( you would then hear the other station.)

Consult your communications officer for use of the this formality and

see if it applies to your agency. Transmit only when the channel is

clear. If the radio was set up for BCL (Bust Channel Lock out), a Beep

will be heard from the radio speaker indicating that the channel is occu-

pied, and will not allow you to turn the transmitter on using the PTT key

until the channel is clear.

7.0 To Access Keypad controlled functions

Your K-911 has been programmed at the factory with defaulted channels and certain

functions that are enabled at the factory. Many may be changed by way of accessing

the Main Menu Options per bank and channel. Select the bank, then the channel,

then access the MENU OPTIONS as described below.

HOLDING DOWN THE KEY WILL ALLOW YOU TO CHANGE THE

BANKS/ZONE ON THE LINE SELECTED.
