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 arefrigerator 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 aTV
or VCR; and, if interference is experienced,
moving the cordless telephone farther away
~from the TV or VCR will often reduce or
1eliminate 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.

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 acontinuous 12
hours.

‘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 3weeks of continuous standby time. (Listed standby time is measured
under asituation 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
every time you answer or place acall using
the handset, aclear channel from 10 frequen- 0
ties available to transmit signals between the
base station and handset. If you notice
interference durina acall, simcrlv mess the
CAUTION
This telephone is for use “tone dialing
system” only.
If you have apulse 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:
IAfter the handset battery is replaced or exhausted
iAfter apower interruption
To reset your security code

2.
Place the handset in the base station
cradle.
Within 8seconds, press ~1

The IN USE indicator blinks. Abeep
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 4minutes. When this occurs,
repeat the steps above.
If you experience difficulty in resetting the
security code, first disconnect the AC

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).

TEST MODE
*(6) Key Monitor detection
Each time akey 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.
(1) Initial status (Simultaneously pressed)
TX POWER TX MUTE RX POWER RX MUTE CH pressed
Key monitor mode OFF ON ON ON 10 1 and O
(2) Battery low detection
The BATT LOW LED and buzzer is set on for 500msec.
&The BATT LOW LED is operated by Integrated circuit (ICO02).
(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 aspecific 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.

TEST MODE k
QBASE 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.
P42 (17pin) P43(18pin) MODE
(TP2) (TP1)
HIGH Usual Mode
HIGH LOW Test Mode (Remote Unit Call)
HIGH Test Mode (DTMF Output)
LOW LOW Test Mode (PULSE Output)
(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 3states. Description of state is explained in below table.
State Name Description LED
1Remote Unit Call IN USE
2DTMF Output Output”1”, “5”, “9 and”# of DTMF repeatedly. CHARGE
3PLUSE Output Output “l”, “2 and “PAUSE” of PLUSE repeatedly. IN USE
CHARGE
4. PLL Channel setting
How to set up PLL Channel below.
Range of channel is 1to 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 7ch.
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 1ch.
(5) Since pressing the PAGE key, both Tx and Rx Channels change as below.
