Before returning any models to the customer, a safety check of the entire instrument should be made.
The service technician must be sure that no protective device built into the instrument by the manufacture
has become defective or inadvertently degraded during servicing.
1.WARNING:
Alterations of the design or circuitry of these models should not be made.
Any design changes or additions such as, but not limited to, circuit modifications, auxiliary speaker
jacks, switches, grounding, active or passive circuitry, etc. may alter the safety characteristics of these
models and potentially create a hazardous situation for the user.
Any design alterations or additions will void the manufacturer's warranty and will further relieve the
manufacturer of responsibility for personal injury or property damage resulting therefrom.
2.PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special characteristics. These characteristics
often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc. Replacement parts that have these
special safety characteristics are identified in this manual and its supplements; electrical components
having such features are indentified by a in the schematic diagram and the parts list. Before
replacing any of these components, read the parts list in this manual carefully. The use of substitute
replacement parts that do not have the same safety characteristics as specified in the parts list may
create shock, fire or other hazards.

TROUBLESHOOTING HINTS
1. The bell does not ring.
When the INTCOM of the
base is pressed, does the
ringer on the handset ring?
When the TEL SG is joined
with the base to make bell
signal, is there pulse wave at
pin 4 of IC5?
Is there pulse wave at
pin 49 of IC8?
Check IC8 and its
peripheral circuit.

Check R179.
If you want to reset the unit to the factory settings
You can cancel the OGM, PIN, and the clock settings by the following process.
1) Disconnect the AC adaptor and telephone line cord from the base. Keep the A C adaptor connected to the wall
outlet. Make sure that the telephone line cord remains disconnected during this procedure.
2) While pressing the DELETE button, plug the AC power adaptor into the base. Keep pressing the DELETE
button for more than 4 seconds .
A beep sounds and “ P” blinks in the LED display.
To resume using the unit, connect the telephone line cord and place the handset on the base.
Note:
If you turn on the unit again, “ P” may flash.
HANDSET
Deletion of the Caller ID memory
To delete the Caller ID memory in the EEPROM, proceed with the following process:
1) Connect the battery with pressing and # buttons, and keep pressing the buttons continuously for
approximate 2 seconds.
2) Release buttons when entering TEST mode with beep.
3) Press CID button.
4) A confirmation beep will sound after about 8 seconds, then the data for caller ID is deleted.
(Note: Do not disconnect the battery until you hear the confirmation beep, otherwise the data may not be
completely deleted.)
