CAUTION ON REPLACEMENT OF OPTICAL PICKUP
The laser diode in the optical pickup block is so sensitive to
static electricity, surge current and etc., that the components
are liable to be broken down or its reliability remarkably
deteriorated.
During repair,carefully take the following precautions.
(The following precautions are included in the
. service
parts.)
PRECAUTIONS
1.Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with impedance lower than 10 Mohm) on the workdesk and place the set on the conductive sheet so that
the chassis can be grounded.
3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.
2.Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.
4. Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.

5. Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs a laser. Therefore, be sure to follow carefully
the instructions below when servicing.
WARNING!!
SERVICE WARNING : DO NOT APPROACH THE
LASER EXIT WITH THE EYE TOO CLOSELY.
IN CASE IT IS NECESSARY TO CONFIRM LASER
BEAM EMISSION, BE SURE TO OBSERVE FROM
A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE
OPTICAL PICK-UP BLOCK.
Laser Diode Properties
Material: GaAS/GaALAs
Wavelength: 780nm
Laser output: max. 0.5mW*
Emission Duration: continuous
*This output is the value measured at a distance about 1.8mm
from the objective lens surface on the Optical Pick-up Block.

1. Replacing the fuses
3. Safety-check out
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjest to the symbol.
(Only U.S.A. model)
After correcting the original service problem perform the
follwing safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10Mohm at 500V
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme

4. Memory Preservation
REF.NO.
F901
This unit does not require memory preservation batteries. A built-in
memory power back-up system preserves the contents of the
memory during power failures and even when the unit is un-plugged.
The unit must be plugged in order to charge the back-up
system.
The memory preservation period after the unit has been unplugged
varies depending on climate and placement of the unit. On the
average, memory contents are protected over a period of a few
weeks after the last time the unit has been unplugged. This period
is shorter when the unit is exposed to a highly humid climate.

OPERATION OF THE MICROPROCESSOR
OPERATION OF THE MICROPROCESSOR TERMINAL LINKED WITH THE ENERGY SAVE FUNCTION
In the energy save mode (including the preparation period). only the STANDBY/ON button and the ENERGY SAVE button can be operated.
60 seconds after the energy save is operated. the microprocessor is turned to the energy save mode.
Even if the AC cord is removed. the energy save mode is stored. (the stored period is about 2 or 3 weeks that are the same as the stored
period of the preset values for the tuner.) When the initial values are set. the energy save mode is released.
(*1) : The back-up voltage for the microprocessor is supposed to be 0 volt after the initial values are set.
(*2) : The energy save mode is set when the power supply is on.
When the ENERGY SAVE button is pressed in the stand-by state. you can also enter the energy save mode.
