How to Discharge the E.Capacitor on Flash P.C.B.

CAUTION:

1.

Be sure to discharge the E.capacitor on FLASH P.C.B..

2.

Be careful of the high voltage circuit on FLASH P.C.B. when servicing.

[Discharging Procedure]

1. Refer to the disassemble procedure and remove the necessary parts/unit.
2. Install the insulation tube onto the lead part of resistor (ERG5SJ102:1k

Ω

 /5W).

(An equivalent type of resistor may be used.)

3. Place a resistor between both terminals of E.capacitor on the FLASH P.C.B. for approx. 5 seconds.
4. After discharging, confirm that the E.capacitor voltage is lower than 10V by using a voltmeter.
