POWER SUPPLY DURING REPAIRS
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.

This following two methods are available to prevent this. Take note of which to use during repairs.
Method 1.
Use the AC power adaptor.
Method 2.
Connect the servicing remote commander RM-95 (J-6082-053-B) to the LANC jack, and set the commander switch to the “ADJ” side.

NOTES ON HANDLING THE OPTICAL PICK-UP
The laser diode may suffer electrostatic breakdown because of the
potential difference generated by the charged electrostatic load, etc.
on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.

PRECAUTION FOR CHECKING EMISSION OF
LASER DIODE
LASER DIODE
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.

1.
SELF-DIAGNOSIS FUNCTION
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.
Details of the self-diagnosis functions are provided in the Instruction
manual.

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

Note:
The self-diagnosis display data will be kept even if the lithium battery (BT6151 of FP-204) is removed.
