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 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.
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
the OPR LED (D502),
4. In case of OK, press the STOP  button.
Note :
In case of NG, check system control IC (IC704), flash memory
IC (IC701) and the peripheral circuit. (Particularly, check care-
fully the soldering of the flash memory)
After finishing the BAD-BLOCK check, assemble the set, load
the dry battery, and confirm if the set operates normally.

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-
