12.2.4. Adjust Battery Low Detector Voltage (Handset)
After handset's DSP (IC501) or EEPROM (IC541) replacement, Re-writing Battery Low voltage to EEPROM is required.
With following handset Adjustment Flow, adjust DC power supply and DC voltmeter by the procedure below.
1. Set DC power supply to 2.6 V.
2. Set up handset in TEST mode (Adjustment flow).
3. Press [1] key and [OFF] key to Adjust Batt Low mode. (“Bat Adj.” is displayed on LCD)
4. Change the voltage of the DC power supply to 2.34 V accurately. Check the voltage at P.C. board pads because some voltage
drops occur due to the usage of long or thin cables.
5. Press [TALK] key twice to write voltage value in EEPROM.
6. Press [TALK] key twice to write charge value 1 in EEPROM.
7. Change the voltage of the DC power supply to 3.1 V accurately.
8. Press [TALK] key twice to write charge value 2 in EEPROM.
9. Change the voltage of the DC power supply to 3.6 V accurately.
10. Press [TALK] key twice to write primary battery detect value in EEPROM.
11. Turn the power off. Then this value is available.

12.2.5. Things to Do after Replacing IC (for BT Unit)
After replacing DSP or Program Flash on the BT board, the following adjustments are needed.
Turn the unit power on then start test mode with U-ART Jig on the main board.
Note:
: Enter key
: Space key
(*1) Connect Frequency Counter to the P.C.Board. Refer to
Base Unit Reference Drawing
(P.97).
(*2) XX and YY are hexadecimal data. Frequency decreases when the value of XX, YY increase, while it increases when XX,
YY decrease.
(*3) $$ and ## are hexadecimal data. $$, ## = 01
