• Adjustment method of Vrem PWM Duty (H)
(item number: 766)
1. Connect a digital voltmeter to the TP919 (VR) on the MAIN
board, and adjust
[VOL +] key (voltage up) or [VOL --] key
(voltage down) so that the voltage becomes 2.6 V.
2. When press the X key to write the adjusted value, LCD
displays as follows and power supply manual adjustment has
completed.

r
2. Normal charging current adjustment (item number 721)
r
3. Trickle charging current adjustment (item number 722)
• Adjustment method of charging detection set value
(item number 757)
1. Connect a resistor 2.4 Ω between TP901 (BATT+) and TP902
(BATT-) on the MAIN board.
2. Apply 2 V across TP901 (BATT+) and TP904 (SET GND),
and across TP903 (2V IN) and TP904 (SET GND) on the
MAIN board respectively.
3. Select the manual mode of the test mode, and set item number
757 (see page 13).
4. Adjust with [VOL +] key or [VOL --] key so that the adjusted
value becomes 1.
If the adjusted value is already attained, go to the next
adjustment item without pressing the X key.
5. Press the X key to write the adjusted value.
