In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4V), the power is shut off so
that the unit cannot operate.
This following two methods are available to prevent this. Take note of which to use during repairs.

Use the AC power adaptor (AC-L10, AC-VQ800 etc.).

Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the “ADJ” side.

The power supply capacitor of the flash unit is charged up to the maximum 300V 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 1k

Ω/1W (1-215-869-11).

Wrap insulating tape fully around the reads of the resistor to prevent electric shock.

1

Remove the power supply (Battery or AC power adaptor).

2

Open the cassette lid (grip cabinet).

3

Remove the two screws with which the grip cover is fixed.

4

Remove the grip cover.

5

Remove the insulation sheet.

6

Short circuit between 3 and # terminal of the capacitor with the short jig about 10 seconds.

When installing the grip cover, insert it in the claws of the grip cabinet.

When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder, LCD screen
or LCD window what to do. This function consists of two display;
self-diagnosis display and service mode display.
Details of the self-diagnosis functions are provided in the Instruction
manual.

When problems occur while the unit is operating, the counter of the
viewfinder, LCD screen or LCD window consists of an alphabet
and 4-digit numbers, which blinks at 3.2 Hz. This 5-character display
indicates the “repaired by:”, “block” in which the problem occurred,
and “detailed code” of the problem.

The service mode display shows up to six self-diagnosis codes shown in the past.

While pressing the “STOP” key, set the switch from OFF to “VCR”, and continue pressing the “STOP” key for 5 seconds continuously. The
service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [  ] indicates the order in which the
problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)
[1] : Occurred first time

[4] : Occurred fourth time

[2] : Occurred second time

[5] : Occurred fifth time

[3] : Occurred third time

[6] : Occurred the last time

Turning OFF the power supply will end the service mode display.
