1-1. NOTE FOR REPAIR

Make sure that the flat cable and flexible board are not cracked of
bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)

1-2. DISCHARGING OF THE FLASH UNIT'S CHARGING CAPACITOR

The charging capacitor of the Flash unit is charged up to the
maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
battery is handled by hand. The electric shock is caused by the
charged voltage which is kept without discharging when the main
power of the unit is simply turned off. Therefore, the remaining
voltage must be discharged as described below.

1-2-1. Preparing the Short Jig

To preparing the short jig, a small clip is attached to each end of a
resistor of 1 kΩ /1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to prevent
electrical shock.

When remove a connector, don't pull at wire of connector.
It is possible that a wire is snapped.
When installing a connector, don't press down at wire of connector.
It is possible that a wire is snapped.

1-2-2. Discharging the Capacitor

Short-circuit between the positive and the negative terminals of
charged capacitor with the short jig about 10 seconds.
