SAFETY PRECAUTION FOR SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.
However, 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.
VOLTAGE SELECTION
The voltage selector is located on the AC voltage selector box. If adjustment is necessary, use a screwdriver in order to turn the
selector in either direction unitil the correct voltage figure is displayed in the window next the adjustment screw.

AM/FM interval (span)
The International Telecommunication Union (ITU) has established that member countries should maintain either a 10 kHz or a 9 kHz interval between broadcasting frequencies of any AM station. The illustration shows the 9 kHz interval zones (regions 1 and 3), and the 10 kHz interval zone (region 2). Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to AM tuning interval (span) of your area.
To change the tuning zone: 1
Press the ON/STAND-BY button to enter the stand-by mode.
2
Set the SPAN SELECTOR switch to "50/9" for 9 kHz AM interval (50 kHz FM interval), and "100/10" for 10 kHz AM interval (100 kHz FM interval).

Whilst pressing down the button and the X-BASS/DEMO button, hold down the ON/STAND-BY button for at least 1 second.
●"CLEAR AL" will appear. Caution: ●The operation explained above will erase all data stored in
memory including clock and timer settings, and tuner and CD presets.
■
Connecting the AC power lead
Check the setting of the AC voltage selector located on the rear panel before plugging the unit into an AC socket. If necessary, adjust the selector to correspond to the AC power voltage used in your area. Selector adjustment: Turn the selector with a screwdriver until the appropriate voltage number appears in the window (110V, 127V, 220V or 230V - 240V AC). Notes: ●Plug the AC power lead into a convenient AC socket, after
any connections.
●Unplug the AC power lead from the AC socket if the unit will
not be in used 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 electric shock or fire.
●AC Plug Adaptor In areas (or countries) where an AC socket as shown in illustra- tion ②is used, connect the unit using the AC plug adaptor sup- plied with the unit, as illustrated. The AC plug adaptor is not included in areas where the AC wall socket and AC power plug can be directly connected (see illustration ①).

[Error during close operation]
0101 Open/Close SW Low → High not functioning
0103 Open/Close SW High →Low not functioning
[Error during open operation]
0201 Open/Close SW Low → High not functioning

or Disc SW do not change to low.
0307 Clamp SW Low → High not functioning
0308 Clamp SW High →Low not functioning
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacingthepickup.Therefore,differentPWBsandpickups
can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.
Items adjusted automatically
(1) Offset adjustment (The offset voltage between the head
amplifier output and the VREF reference voltage is
compensated inside the IC.)
* Focus offset adjustment
* Tracking offset adjustment
(2) Tracking balance adjustment (waveform drawing 13-2
EFBL)
(3)Gainadjustment(Thegainis compensatedinside theIC
sothatthe loop gain at the gain crossover frequency will
be 0dB.)
* Focus gain adjustment
* Tracking gain adjustment
