When “FLASH error”  (Self-diagnosis Code  E : 91 : 01) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash
is changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the HOME screen.

Initializes the setting to the default setting.
Even if you execute this function, the images are retained.

• 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.

• 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.

• Do not apply excessive load to the gilded flexible board.

Cut and remove the part of gilt 
which comes off at the point.
(Be careful or some 
pieces of gilt may be left inside) 

The charging capacitor (C901) of the AF-121 flexible board is
charged up to the maximum 315 V potential.
There is a danger of electric shock by this high voltage when the
capacitor 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.

To preparing the short jig, a small clip is attached to each end of
a resistor of 1 k

Ω /1 W (1-215-869-11).

Wrap insulating tape fully around the leads of the resistor to
prevent electrical shock.

Wrap insulating tape.

Note: High-voltage cautions

Discharging the Capacitor
Short-circuit between the two points 
with the short jig about 10 seconds.
To avoid the spark with the metal plate,
wrap the short jig with the insulation tape.
