Using the Controls

BASE UNIT CONTROLS

Take a moment to familiarize yourself with the controls on the base unit

(Figure 1).

FIGURE 1 The base unit.

Retractable antenna

When the handset is removed from the base unit, this antenna must

be fully extended so that you can receive all incoming calls and have

clear, strong reception.

Power cord with ac adapter

To power the base unit, plug the power cord into a grounded, 3-prong

ac outlet that is not controlled by a switch.

iss1, cib3126-2

Handset Hook

When the cordless voice terminal is wall mounted, the handset hook

allows the handset to be securely placed into the base unit.

Directory Card

The directory card is provided so that you can write the Intercom

(ICOM) Number/Personal Dialing Code (PDC) assigned to the cord-

less voice terminal and the ICOM No./PDC and names of other peo-

ple on the system. When you have more than one MLC-5 Cordless

Voice Terminal in an area, it is especially important to write the ICOM

No./PDC assigned to each of them to help ensure that the proper

handsets are always placed into their correct base units.

Battery Contacts

Batteries begin recharging when the battery contacts on the handset

touch the contacts on the base unit. Periodic cleaning of the con-

tacts using a soft eraser may be necessary.

Channel Indicator

The channel indicator lights to identify which channel is currently

being used or being programmed. A “P” is displayed when the cord-

less voice terminal is in programming mode.

Mode

There are three modes of operation:

The Charge light comes on whenever the handset is properly

placed in the base unit and indicates that the batteries are being

recharged.

The Talk light comes on whenever the handset is removed from

the base unit and is turned on with the On/Off button.

The Program light comes on when the T/P switch is set to P for

programming mode.

T/P Switch

The T/P switch is used to test the voice terminal and to program

channels and features.

Ringer Vol

The ringer volume switch adjusts the volume of the base unit ringer.

Slide it to the right (increases loudness) or to the left (decreases

loudness) to adjust the level. The handset ringer volume cannot be

changed.

Message

The message light goes on steady whenever there is a message for

you.

HANDSET CONTROLS

Take a moment to look over the controls that operate the handset (Fig-

ure 2).

FIGURE 2 The handset.

Antennas

Two antennas are provided with the handset: a retractable antenna

and a flexible antenna.

WARNING: Never operate the handset outside during an electrical

storm.

Retractable Antenna (factory installed)

Whenever the handset is removed from the base unit, this

antenna should be fully extended to receive calls and for clear

reception.

iss1, cib3126-4

Flexible Antenna (packaged separately)

This antenna can replace the retractable antenna so that the

handset is easier to carry when placed in the carrying adapter.

On/Off

The light next to this button must be on when you answer or make a

call. Two beeps sound if the handset is out of range and must be

moved closer to the base unit.

Message

When the light is on next to this button, there is a message for you.

The light blinks after 20 seconds to conserve battery power.

Lo Batt

This light blinks and a tone sounds when the batteries have fewer

than 15 minutes of use remaining.

Line Card Label

The line card label next to the blank buttons can be marked with a

ballpoint pen, not a pencil, to indicate which features or lines are

assigned to the corresponding button. If you need to make correc-

tions or updates, you can erase the label, but do not remove it.

Line/Feature Buttons

For MERLIN Systems, of these five programmable buttons, four are

initially reserved for outside lines and one, located to the left of

On/Off, is an intercom line. Any of the four outside line buttons can

be programmed with MERLIN System features.

For System 25, of the five programmable buttons, the last two on the

bottom row are System Access buttons reserved for making and

receiving calls. Any of the three remaining buttons can be pro-

grammed with System 25 features.

Status

In order to conserve battery power, the lights on the handset (except

On/Off) go off in 20 seconds. When this button is pressed the indica-

tor lights relight to reflect the current status of calls and features. If

the handset is out of range when Status is pressed, you hear two

short beeps that indicate the handset must be moved closer to the

base unit.

Trans

Press this button when you want to transfer a call to another number.

Hold

Press this button to place a call on hold.

Dial pad

The dial pad is used for dialing numbers and entering programming

Channel

During normal operation, press this button to change channels for

clearer reception. In cases of strong interference, you may have to

move closer to the base unit in order to change channels. If the

handset is out of range, two short beeps sound to indicate that the

handset must be moved closer to the base unit.

When the cordless voice terminal is in programming mode, press this

button to program channel selection.

Number Card

This card should be removed, labeled with the ICOM No./PDC

assigned to the cordless voice terminal, then replaced. This is espe-

cially important when you have more than one cordless voice termi-

nal in an area to ensure that the handset is always placed into the

correct base unit.

Battery Contacts

Batteries begin recharging when the battery contacts on the handset

touch the contacts on the base unit. Periodic cleaning of the contacts

using a soft eraser may be necessary.

Installation

The base unit for the cordless voice terminal may be placed on a desk or

table top or mounted on a wall not made of metal. Instructions for each

installation follow.

BEFORE YOU BEGIN

Before you install the cordless voice terminal, there are certain con-

siderations regarding its location and use:

●

The base unit must be installed at least 20 feet away from the control

unit for optimum range.

The base unit should not share the same power line or be within 6

feet of electromagnetic equipment such as electric motors, or equip-

ment with microprocessors such as answering machines, personal

computers, and FAX machines.

Never operate the handset outside during an electrical storm.

If there are other people using cordless voice terminals in the area,

they cannot share the same channels. Follow the instructions for

“Programming Channels” to assign different channels to each voice

terminal.

iss1, cib3126-6

●

If more than one cordless voice terminal is being used, do not place a

handset from one cordless voice terminal into the base unit of

another. If this accidentally occurs place the proper handset in its

corresponding base unit for at least 10 seconds.

The range of your cordless voice terminal may be reduced when

operating the handset around metal walls.

There is no visual indication on the handset when a call is being

bridged. If you need to ensure privacy on a line, program the

Privacy/Exclusion feature onto one of the line/feature buttons on the

handset, then activate it during the call. See “Using the Feature But-

tons” for details.
