SAFETY PRECAUTION FOR SERVICE MANUAL

WARNINGS

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER
COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. THEREFORE IT IS
IMPORTANT THAT THE FOLLOWING PRECAUTIONS ARE OBSERVED DURING SERVICING TO PROTECT YOUR EYES
AGAINST EXPOSURE TO THE LASER BEAM.

1-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED ON WITHOUT A COMPACT DISC IN POSITION AND THE

PICKUP IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR SEVERAL SECONDS TO DETECT A DISC. DO NOT
LOOK INTO THE PICKUP LENS.

2-THE LASER POWER OUTPUT OF THE PICKUP UNIT AND REPLACEMENT SERVICE PARTS ARE ALL FACTORY

PRESET BEFORE SHIPMENT.

DO NOT ATTEMPT TO READJUST THE LASER PICKUP UNIT DURING REPLACEMENT OR SERVICING.
3-UNDER NO CIRCUMSTANCES STARE INTO THE PICKUP LENS AT ANY TIME.
4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE

SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

VOLTAGE SELECTION

Before operating the unit on mains, check the preset voltage. If the voltage is different from your local voltage, adjust the voltage
as follows.
Turn the selector with a screwdriver until the appropriate voltage number appears in the window (110 V, 127 V, 220 V or 230 V-240 V AC).

System Connections

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.

T urn the s elec tor with a s cre wdriv er unti l the a ppropriate voltage num­ber appears in the window (110 V, 127 V, 220 V or 230 V - 240 V AC).

Connecting the AC power lead

After making all connections, plug the unit. If you plug the unit first,
the unit will enter the demonstration mode.

Note:

Unplug the AC power lead from the wall socket if the unit will not be in use for a pro­longed period of time.

AC Plug Adaptor

In areas (or countries) where a wall socket as shown in i llustration 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 FM/AM span selector

The International T elecomm unication Union (ITU) has established that member coun­tries should maintain either a 100 kHz or a 50 kHz interval between broadcasting fre­quencies of FM stations and 10 kHz or 9 kHz for AM station. The illustration shows
the 50/9 kHz zones (regions 1 and 3), and the 100/10 kHz zone (region 2).
Before using the unit, set the SPAN SELECTOR switch (on the rear panel) to the
interval (span) of your area.

To change the tuning zone:

Caution:

This operation will erase all data stored in memory including clock, timer settings,
tuner preset, and CD programme.

1 Press the ON/STAND-BY button to enter the stand-by mode.
2 Set the SPAN SELECTOR switch (on the rear panel) as follows.

For 50 kHz FM interval (9 kHz in AM) 50/9
For 100 kHz FM interval (10 kHz in AM) 100/10

3 Whilst pressing down the button and the MONSTER-BASS button, press the ON/

STAND-BY button until "CLEAR AL" appears.

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

Fig.14-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will
be 0 dB.)

* Focus gain adjustment
* Tracking gain adjustment

• Adjustment
Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWBs and pickups
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.
