CAUTION-1. (When servicing MAIN C.B.A. / STROBE UNIT)
1. Be sure to discharge the capacitor on MAIN C.B.A. after removing the Rear case unit.
Refer to “HOW TO DISCHARGE THE CAPACITOR ON MAIN C.B.A.”.
The capacitor voltage is not lowered soon even if the AC Cord is unplugged or the battery is removed.
2. Be careful of the high voltage circuit on MAIN C.B.A.
3. DO NOT allow other parts to touch the high voltage circuit on MAIN C.B.A.
CAUTION / IMPORTANT. (WHEN HANDLING THE MAIN C.B.A.)
1. DO NOT PRESS AND BENT THE JUNCTION AREA OF MAIN C.B.A.
Since the Terminal board, Main board and Digital board of the Main C.B.A. are directly connected with Flexible Card, these
junction areas are quite delicate.
junction areas are quite delicate.
Therefore, DO NOT hardly press and bent the junction areas of Main C.B.A.

7.3. HOW TO DISCHARGE THE CAPACITOR ON MAIN C.B.A.
CAUTION:
1. Be sure to discharge the capacitor on MAIN C.B.A. after removing the Rear case unit.
2. Be careful of the high voltage circuit on MAIN C.B.A. when servicing.
[Discharging Procedure]
1. Refer to the disassemble procedure and Remove the necessary parts/unit.
2. Peel off the Insulation Barrier.
3. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k
Ω
/5W).
(an equivalent type of resistor may be used.)
4. Put the resistor between both terminals of capacitor on MAIN C.B.A. for approx. 5 seconds.
5. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.
