OPERATION MANUAL

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.

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).

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 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 ).

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:

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

CD SECTION

• 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.

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

Measure to be taken when a disc cannot be removed due to a mechanism trouble

First, remove the mechanism unit section from the set, and check for the state of the disc.
(Remove the top plate R if necessary.)
<State of the disc>
(1) When the disc is in the normal PLAY (chucking) position → Try to eject the disc by turning the mode big gear/tray big gear

manually.
* At this time, be sure to adjust the tray's position (height).

(2) When the disc is in the normal STOCK position → Try to eject the disc by turning the tray big gear manually.

* At this time, be sure to adjust the tray's position (height).

(3) When the disc is not in the normal position → The tray or disc is not in the normal position.

(The tray or disc may catch somewhere.)

↓

Remove the TOP PLATE F/DISC OB lever.
Unlock the tray lock lever and pull out the tray which is not caught.

Move the caught tray or disc and remove the disc.
In case of (1) and (2), the mechanism is normal (defective circuit parts, etc.). However, it may stop somewhere.
This is the reason why you should try to turn the tray big gear first.
In case of (3), either of the big gears does not turn.
