Note 1: The back light (fluorescent tube) is driven by a high voltage
AC power supply. Therefore, do not touch the back light
holder to avoid electrical shock.
Note 2: When replacing the LCD unit, be careful to prevent damages
caused by static electricity.
Note 3: Set the VF PW-SAVE (Menu display) to “OFF” position,
unless specified otherwise.

concentrated in CN9928 of the CB-58 board.
Connect the measuring instruments via the CPC-8 jig (J-6082-388-
A).
The following table shows the Pin No. and signal name of CN9928.
Adjusting method:
1) Set data: 01 to page: 0, address: 01.
2) Select page: D, and input the data in the following table.
Note: To write in the non-volatile memory (EEPROM), press
