How to Discharge the Capacitor on Flash SD P.C.B.
CAUTION:
1. Be sure to discharge the capacitor on FLASH SD P.C.B..
2. Be careful of the high voltage circuit on FLASH SD P.C.B. when servicing.

Before disassembling, perform "6.6. Forced full flash emission" for discharging capacitor.
The capacitor also can be discharged according to the following procedures.
The capacitor also can be discharged according to the following procedures.
[Discharging Procedure]
1. Refer to the disassemble procedure and Remove the necessary parts/unit.
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k
2. Put the insulation tube onto the lead part of Resistor (ERG5SJ102:1k
Ω /5W).
(an equivalent type of resistor may be used.)
3. Put the resistor between both terminals of capacitor on FLASH SD P.C.B. for approx. 5 seconds.
4. After discharging confirm that the capacitor voltage is lower than 10V using a voltmeter.
