This product is classified as a CLASS 1 LASER PRODUCT.
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output is less than Class 1 but the laser component is capable of emitting
radiation exceeding the limit for Class1. Therefore it is important that the following precautions must be observed during servicing
to protect your eyes against exposure to the Laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than
the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) TheLaserPowerOutputofthePickupinsidetheunitandreplacementservicepartshavealreadybeenadjustedpriortoshipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
SAFETY PRECAUTION FOR SERVICE MANUAL

Remote Control
■Battery installation
Precautions for battery use:
●Replace all old batteries with new ones at the same time.
●Do not mix old and new batteries.
●Remove the batteries if the unit will not be used for long periods
of time. This will prevent potential damage due to battery leak-
age.
Caution:
●Do not use rechargeable batteries (nickel-cadmium battery, etc.)
●Installing the batteries incorrectly may cause the unit to malfunc-
tion.
Notes concerning use:
●Replace the batteries if the operating distance is reduced or if the
operation becomes erratic. Purchase 2 "AAA" size batteries (UM-
4, R03, HP-16 or similar).
●Periodically clean the transmitter on the remote control and the
sensor on the unit with a soft cloth.
●Exposing the sensor on the unit to strong light may interfere with
operation. Change the lighting or the direction of the unit.
●Keep the remote control away from moisture, heat, shock, and
vibrations.
1 Remove the battery cover.
2 Insert the batteries according to the direction indicated in
the battery compartment.
When inserting or removing thebatteries, push them towards the
battery terminals.
3 Replace the cover.
Troubleshooting
■If trouble occurs
When this product is subjected to strong external interference
(mechanical shock, excessive static electricity, abnormal supply
voltage due to lightning, etc.) or if it is operated incorrectly, it may
malfunction.
If such a problem occurs, do the following:
Caution:
●This operation will erase all data stored in memory including
clock, timer settings, tuner preset, and CD programme.
●After the above operation, interval span setting for AM will be
returned to 9 kHz (50 kHz for FM) automatically.
1 Set the unit to the stand-by mode and turn the power on
again.
2 If the unit is not restored in step 1, unplug and plug in the
unit, and then turn the power on.
3 If neither step 1 nor 2 restores the unit, do the following:
Press the ON/STAND-BY button to enter the power stand-by
mode.
Unplug the AC power lead from the AC INPUT socket on the
unit.
Whilst pressing down the MEMORY/SET button and the
button, plug the AC power lead into the AC INPUT socket on
the unit.

System Connections (continued)
■Setting the AC voltage selector
Check the setting of the AC voltage selector located on the rear
panel before plugging the unit into a wall socket. If necessary, adjust
the selector to correspond to the AC power voltage used in your
area.
Turn the selector with a screwdriver until the appropriate volt-
age number appears in the window (110 V, 127 V, 220 V or 230 V
- 240 V AC).
■Connecting the AC power lead
After checking all the connections have been made correctly,
connect the AC power lead to the AC power input socket, then
into the wall socket.
Notes:
●Unplug the AC power lead from the wall socket if the unit will not
be in use for a prolonged period of time.
●Never use a power lead other than the one supplied. Use of a
power lead other than the one supplied may cause an elec-
tric shock or fire.
AC Plug Adaptor
In areas (or countries) where a wall socket as shown in illustration
is used, connect the unit using the AC plug adaptor supplied with
the unit, as illustrated. The AC plug adaptor is not included in areas
where the wall socket and AC power plug can be directly connected
(see illustration ).

■Setting the AM/FM interval
The International Telecommunication Union (ITU) has established
that member countries should maintain either a 10 kHz or 9 kHz
interval between broadcasting frequencies of AM stations and 100
kHz or 50 kHz for FM stations. The illustration shows the 50/9 kHz
zones (regions 1 and 3), and the 100/10 kHz zone (region 2).
This product is not equipped with a span selector. However, it will be
adjusted to a 9 kHz AM (50 kHz FM) interval when shipped from the
factory.
Before using the unit, be sure to set it to the AM/FM tuning interval
(span) used in your area.
To check the tuning span currently selected:
To change from a 9 kHz AM (50 kHz FM) interval to a 10 kHz AM
(100 kHz FM) interval:
To return to a 9 kHz AM (50 kHz FM) interval:
Caution:
●When the unit is left for a few hours after the span has been
switched and the AC power lead disconnected, the AM span will
be automatically returned to 9 kHz (FM span to 50 kHz). If this
happens, set the span again.
●When the span is switched, all the memorised stations will be
cancelled.
1 Press the ON/STAND-BY button to turn the power on.
2 Press the FUNCTION button until "AM" appears on the display.
●If "AM 531 kHz" is displayed, it means that AM stations have
been adjusted for a 9 kHz span and FM stations for 50 kHz
span. If "AM 530 kHz" is displayed, AM stations have been ad-
justed for a 10 kHz span and FM stations for 100 kHz span.
1 Press the ON/STAND-BY button to enter the stand-by mode.
2 Hold down the button and the MEMORY/SET button for at
least 4 seconds. Release the buttons when "AM SP 10 kHz" and
"FM SP 100 kHz" are displayed alternately.
●The clock display will reappear.
1 Press the ON/STAND-BY button to enter the stand-by mode.
2 Hold down the button and the MEMORY/SET button for at
least 4 seconds. Release the buttons when "AM SP 9 kHz" and
"FM SP 50 kHz" are displayed alternately.
●The clock display will reappear.

1. Turning on the test mode
For obtaining each test mode, press the ON/STAND-BY
button, while keeping pressing the following two buttons in
the ordinary stand-by mode (power off ). In this case, the
main unit buttons are valid. When turning the ON/STAND-
BY on with remote control buttons, test modes are not
obtained.

3. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment
and measurement frequencies in the preset memory
CH. Whenadjusting thetuner sectioninthe production
line,adjustingpersonnelarenotrequiredtosetfrequency.
2. Details of tuner test mode
Press the "REW/PRESET DOWN" and "CD PLAY"
buttons in POWER OFF state and turn on the power by
the use of "ON/STAND-BY" button to preset and store
frequencyforadjustmentandmeasurementofdestination
specified by the AREA terminal in the preset memory
CH. However, Ordinary 1 and Ordinary 2 are stored in
thedestinations(selectedbySPANswitchingoperation)
when the test mode is obtained.
("FF " + "MEMORY/SET" KEY SPAN CHANGE)
(As for frequencies to be preset and stored for each
destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary
operations of TUNER function. FUNCTION switching is
invalid.
It is necessary to discard the content of preset memory
when the tuner test mode is ended; be sure to write "0000"
or "1111" bits in the memory to be checked for judging
memory error at initial setting and to initialize memory.
Whenthe tunertest modeisobtained, the followingdisplay
lights for one second.
• The TUNER TEST2 mode is obtained with
+ MEMORY + ON/STAND-BY.
Turn off AC in the TEST2 mode to restore the initial state.
Turn off POWER to protect the memory of TEST2 mode.
Turn off POWER again to obtain the ordinary operation
while the data is stored in the memory (besides TUNER).
IfAC OFFstate ismaintainedin this stateforabout 1/2day,
start is executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing

This test mode is intended to check whether all the main
unit buttons can be detected. Accordingly, in this test
mode, it is checked whether the "ON/STAND-BY" button
waspressedafterallthebuttonsshownbelowwerepressed.
If the result is OK, OK is displayed. If any one of keys was
not pressed, an error is displayed. In both cases of OK
termination or error termination, the mode is shifted to the
standby mode if the "ON/STAND-BY" button is pressed
subsequently.

Accordingly, it is checked whether all buttons have been
pressed.
