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 1 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) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
(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.

CAUTION

This Mini Component System is classified as a CLASS
1 LASER product.

The CLASS 1 LASER PRODUCT label i s located on the
rear cover.

Use of controls, adjustments or performance of proce­dures other than those specified herein may result in
hazardous radiation exposure.

As the laser beam used in this compact disc player is
harmful to the eyes, do not attempt to disassemble the
cabinet. Refer servicing to qualified personnel only.

OPERATION MANUAL

Connecting the AC power lead

Check the setting of the AC voltage selector located on the
rear panel before plugging the unit int o 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 (110 V, 127 V, 220 V
or 230 V - 240 V AC).

1

AM/FM interval (span)

The International Telecommunication Union (ITU) has
established that member countries should maintain either a
10 kHz or a 9 kHz inter val 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.

2

To an AC socket

Notes:

Plug the AC power lead into an AC socket, after any con­nections.
Unplug the AC power lead from the AC 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 electric shock or fire.

AC Plug Adaptor

In areas (or countries) where an AC 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 AC wall socket
and AC power plug can be directly connected (see illustra­tion ).

Note for users in Australia and New Zealand:

An AC plug adaptor is not supplied if the lead has an Austra­lian Standard plu

.

To change the tuning zone:

1

Press the ON/STA ND-BY button to enter the stand­by mode.

2

Set the SPAN S ELECTOR 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).

3

Whilst pressing down the / button and the
EQUALIZER/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.
