BASE STATION LOCATION

For maximum operating range, extend the

base station antenna to full length, In most

cases, the best location for the base station

is at the highest point in the house. Avoid

places near electrical appliances and metal

structures such as a refrigerator and filing

cabinets that can reduce operating range

and performance.

Caution

The cordless telephone operates at a

frequency that may cause interference to

nearby TVs and VCRs; the base station

should not be placed near or on top of a TV

or VCR; and, if interference is experienced,

moving the cordless telephone farther away

~ from the TV or VCR will often reduce or

1

eliminate the interference.

INITIAL HANDSET BATTERY CHARGE

Install the handset battery (supplied) in the handset and charge the handset for a

full 12 hours before using the cordless phone for the first time.

IMPORTANT: Never attempt to use the cordless phone before this initial battery

charge.

INSTALLING THE HANDSET BAITERY

1.

2.

Slide the lid off the battery

compartment.

Plug the battery cord into the connector

inside the compartment.

3. Place the battery in the compartment.

4. Replace the lid.

CHARGING THE HANDSET

1. Place the handset on the base station for

12 hours.

The CHARGE indicator lights.

● The base station must be connected to

AC power. (See page 11.)

2. Remove the handset from the base

station. Your telephone is now ready to

use.

When the BAIT LOW indicator lights,

recharge the handset for a continuous 12

hours.

REPLACEMENT BAITERY

indicator

‘ If the battery fails, replacement batteries are available from an authorized Sanyo

~ service center.

(Replacement battery: SANYO 3N-270AA)

STANDBY TIME

When the handset battery is fully charged, your Sanyo cordless phone offers up

to 3 weeks of continuous standby time. (Listed standby time is measured

under a situation in which the handset is kept in standby mode only–no phone

calls are made or received). Under normal usage conditions, recharging is

required more often.

1O-CHANNEL ACCESS/AUTO SCAN

This cordless telephone automatically selects,

CHANNEL

time you answer or place a call using

the handset, a clear channel from 10 frequen-

base station and handset. If you notice

interference durina a call, simcrlv mess the

CAUTION

This telephone is for use “tone dialing

system” only.

If you have a pulse dialing line, you can’t

use this cordless telephone.

SECURITY CODES

Your cordless telephone works only when the same security code is selected,

from 65,536 possibilities, for both the handset and base station. This prevents

unauthorized use of your telephone line by another cordless telephone.

IMPORTANT:

The following events may cause the security code to be erased and require

resetting:

I After the handset battery is replaced or exhausted

i After a power interruption

To

reset your security code

1.

2.

Place the handset in the base station

cradle.

Within 8 seconds, press ~1

on the base station.

The IN USE indicator blinks. A beep

sounds and the security code is set.

The IN USE indicator then goes off.

If the security code cannot be set, the

fN USE indicator continues to blink for

about 4 minutes. When this occurs,

repeat the steps above.

If you experience difficulty in resetting the

security code, first disconnect the AC

adaptor from the unit, reconnect it, and

then try again.

1. Overview

By operating the Keyboard SW on the remote, pass/fail of the completion process can be determined through the status of the LEDs,

operation of the key monitor sounds, etc.

Startup

The Test Mode is started up by pressing two keys simultaneously at power on.

(The keys pressed simultaneously differ for the startup of each mode in order to distinguish between them.)

When the Test Mode begins, a beep (completion signal) is sounded.

PLL Channel setting/TX POWER off

1. Setting by the numeric keys

● The numeric key is pressed, then the TX power is turned off TX and RX channels will be set.

● The channels range from 1ch to 10ch and are designated by one numeric key.

10ch is designed by the O key.

If the x key is pressed, the TX power

will be turned on.

TX power can be turned off by pressing either numeric key.

TX data send

By pressing the TALK key, TX DATA

SEND mode is set. At the same time, TX and RX MUTE ON is set (sound modulation mute is

set).

TX DATA send can be terminated by pressing either numeric key.

RX MUTE ON/OFF

RX MUTE ON/OFF switch over each time the CHANNEL key is pressed.

(Effective only under TX POWER ON)

Battery low detection

The BATT LOW LED and buzzer is set on for 500msec.

The BATT LOW LED is operated by integrated circuit (ICO02).

(6) Key Monitor detection

Each time a key is pressed, the TALK LED lights and the key monitor sounds.

(7) Return to the usual mode

By turning off the power and retry, usual mode will start.

5. Key monitor inspection mode

Keys are pressed disorderly, and if after all keys except INT key have been pressed at least once the TALK LED and BATT LED lights

for approximately one second and a buzzer sounds.

(3) Charge detection

When CHARGE is detected, the TALK LED is lit.

(4) Return to the usual mode

By turning off the power and retry, the usual mode will start.

6. Ignore security code mode

Through the base receiving a specific security code and channel (security: AC34H, channel: 10ch), this mode allows linking of the

remote and base without security registration by the remote. Other operations perform as usual.

(1) Startup

The REMOTE enters this mode by simultaneously pressing the 1 and 8 keys.

(2) Return to the usual mode

By turning off the power and retry, the usual mode will start.

Q BASE UNIT SECTION

1. Overview

By operating the connecting IC401 pin23 and groung, and PAGE SW on the base, pass/fail of the completion process can be

determined through the status of the LEDs, operation of the device, etc.

2. Switchover of the Usual Mode and the Test Mode

After Test mode, RAM DATA will be Initialized.

(1) Switchover by operation of Microcomputer ports

This way, the microcomputer ports, P42 (17pin) and P43 (18pin), are used, and the switchover (Test mode and Usual Mode) can

be performed anytime.

(2) Switchover by operation of Power ON

When power on, connect IC401 pin23 and ground , and keep pressing the PAGE key.

Then disconnect IC401 pin23 and ground, and the PAGE key keep off.

Test mode will be Remote Unit Call Status.

In case of Test mode in this way, to switchover the usual mode is either one of the following ways.

1. detect charge

2. turn off the power, retry

3. Types of test modes

Test mode has the following 3 states. Description of state is explained in below table.

4. PLL Channel setting

How to set up PLL Channel below.

Range of channel is 1 to 10 ch for both TX and RX.

When setting the channel, IN USE LED put out 40msec.

(1) When power on, both Tx and Rx Channel are setting 10 ch.

(2) Press the PAGE key, both Tx and Rx Channel are setting 7 ch.

Moreover, RX MUTE will be on.

(3) Next

pressingthe PAGE key, both Tx and Rx Channel are setting 2ch.

(4) Next pressing the PAGE key, both Tx and Rx Channels are setting 1 ch.

(5) Since pressing the PAGE key, both Tx and Rx Channels change as below.
