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.

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.

DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR
The power supply capacitor (ST-118 board JL6501, JL6502) of the flash are charged up to the maximum 300V potential.
There is a danger of electric shock by this high voltage when the capacitors are 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.
