NOTE FOR REPLACEMENT OF THE CRYSTAL VI-
BRATOR ON THE HAND MAIN BOARD
There are two types of crystal vibrators used on the HAND MAIN
board. Accordingly, when replacing the crystal vibrator, replace
the following reference number parts together. Similarly, when
the following reference number parts are replaced, check which
type of crystal vibrator is used and use the same type.

SERVICING NOTES
IF AN ERROR MESSAGE IS DISPLAYED
If the following error message is displayed after the power was turned on, check the items where "1" is indicated.
· Note on Replacing The EEPROM
After the EEPROM was replaced, write various parameters in the "TEST MODE E" (see page 9). (For the ID, see "Writing ID Numbers"
described below)
Note: Replacing the EEPROM causes all data such as customer registered telephone directory to be cleared.
RE-REGISTERING ALREADY REGISTERED SET
Initialize the registered information on this set, and then register again this set by the method given below. When re-registering the handset,
refer to "Registering additional cordless handsets" in the instruction manual. (see page 6)
1. Turn the power on.
2. Press three keys of [1], [EZ ACCESS], and [INTERCOM] simultaneously.
WRITING ID NUMBERS (for registering handsets)
The ID numbers are given in decimal notation on the bottom of base unit. If handsets are registered, ID can be written in the TEST mode,
but the TEST mode handles ID numbers in hexadecimal notation, thus requiring decimal numbers to be converted into hexadecimal
numbers. Accordingly, when registering this set, refer to "Registering a cordless handset" in the instruction manual. (see page 6)
However, if the EEPROM was replaced, the handsets cannot be registered by the method mentioned above. In such a case, enter various
parameters except ID numbers in the "TEST MODE E", and then register the handsets by the method given in the instruction manual.
Also, the ID numbers can be written in the "TEST MODE B"(decimal number) (see page 10).
