Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270°C during
repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or
unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

SERVICING NOTE
Using the special connector jig (J-2503-101-A) to connect the main
board and digital board will prove convenient when servicing the
unit with power applied.

Note :
Do not apply excessive amounts of flux during replace-
ment of electronic components since this may cause elec-
trical shorts due to moisture.
Wipe off flux after electronic components exchange.

CAUTION ON REPLACING FLASH MEMORY
The BAD-BLOCK check* must be executed, when the flash
memory (IC701) in this set was replaced.
The set will not operation normally, unless this check is finished.

The set will not operation normally, unless this check is finished.
* The BAD-BLOCK check detects an area (bad-block) in the flash
memory where data validity cannot be guaranteed, and saves
this information in the TOC-AREA so that a bad-block is not
used.

used.
BAD-BLOCK check procedure :
1. Apply 3V from regulated power supply to the battery
terminals.
2. Once the power is supplied, the check starts and then
proceeds for approx. 3 minutes. (Be sure to keep applying
the power during the check)

3. When the check completes, the result is shown as bellows.
OK : Only the LCD back light LED (D503, 504) turns on.
NG : Red LED blinks or turns on or green LED turns on in

Note :
•
In case of NG, check system control IC (IC704), flash memory
