Notes:
1. When replacing batteries (Ref. No. 10), always iepiace
all three simultaneously.
2. Check the production date of the new batteries. Use only those
produced within the last 3 years (from the date of replacement).

ADJUSTMENTS
_M@ CHARGE VOLTAGE ADJUSTMENT
Perform the following adjustment after replacing IC3, R1, R2, R30,
R39, VR1
and THi.
1. Connect the AC cord to the AC power source (AC 115/200/220/
240 V, 50/60 Hz).
. Set the power switch ON.
. Connect the tester to D4 (cathode) and ground (© line).
. Adjust VR1 for a reading of table 1-A on the tester.
. Connect the tester to D5 (cathode) and ground (© line).
. Confirm that the tester voltage reading agrees with that of table
1-B.
. Connect the tester to D6 (cathode) and ground (© line).
8. Confirm that the tester voltage reading agrees with that of table
1-B.
