These following two methods are available to prevent this. Take note of which to use during repairs.

Use the AC power adaptor (AC-L20, AC-VF50).

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

When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or LCD
screen 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.

The “self-diagnosis display” data will be backed up by the coin-type lithium battery of control switch block (FK-1900) BT001. When CN2024 of
VC-263 board is disconnected, the “self-diagnosis display” data will be lost by initialization.

When problems occur while the unit is operating, the counter of the
viewfinder or LCD screen 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 the last self-diagnosis codes shown in the past.

While pressing the “BACK LIGHT” key, set the switch from OFF to ON, and continue pressing the “BACK LIGHT” 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.

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

Switching of the backup No. can’t be done.

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