This device complies with Part 15 of the FCC Rules, operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesirable operation.

NOTE : This equipment has been tested and found to comply within the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accord­ance with the instruction, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
tuning the equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:

• Reorient or relocate the receiving antenna.

DANGER

LASER SAFETY

This unit employs an optical laser beam system in the CD mechanism, designed with
built -in safeguards. Do not attempt to disassemble, refer to qualified service personnel.

INVISIBLE LASER RADIATION
WHEN OPEN AND INTER­LOCK FAILED OR DEFEATED.
AVOID DIRECT EXPOSURE
TO LASER BEAM.

SAFETY PRECAUTIONS

1. Do not open the cabinet. Refer servicing to qualified personnel only.

2. Do not expose to excessive heat, direct sunlight, dust, moisture, vibration or shock.

3. Use ONLY the AC adaptor provide, others may damage your unit. Disconnect from the wall
outlet when the set is not to be used for an extended period of time.

4. When cleaning your unit, use a soft dry cloth, do not use solvents or commercially available
cleaners as they may damage or discolor the finish.

5. Do not wear headphones while operating a motor vehicle, this could create a traffic hazard
and is illegal in many areas.

6. The headphones supplies with your unit provide super stereo listening while allowing you to
hear outside sounds when listening at normally low volume levels. Listening at extremely
high volume levels minimizes the intrusion of outside noise/sounds.

7. If you notice that the sound has become weak or distorted, this is an indication that your
batteries are low. Replace with new or recharged (see "BATTERY OPERATION")

Exposure to this invisible laser light beam may be harmful to the human eye.
THIS IS A CLASS-1 LASER PRODUCT. USE OF CONTROLS, OR ADJUSTMENTS

OR PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN, MAY RESULT IN
HAZARDOUS LASER LIGHT BEAM EXPOSURE.

CHARGING AND USE OF RECHARGEABLE BATTERIES

Rechargeable Battery Operation

This unit can fully recharge specified rechargeable batteries, in approximately 15
hours. The rechargeable batteries (NOT supplied) should be recharged before
they are used for the first time if they are low in power or they have not been used
for a long period (over 60 days).

1. Open the battery compartment cover and
insert two of the recommended recharge­able batteries, matching polarity. (1.2V
650mA)

BOTH BATTERIES MUST BE OF RE­CHARGEABLE NICKEL-CADMIUM TYPE,
OTHERWISE THE BATTERIES MAY EX­PLODE OR LEAK.

Use the type of rechargeable battery

with negative side exposed area.

2. Connect the supplied AC adaptor's plug to
the DC input jack and corresponding end
to an AC household outlet.

USE ONL Y THE AC ADAPTOR SUPPLIED
WITH THE SET FOR CHARGING.

Note : Charge light will illuminate.

3. After 15 hours, please unplug the AC adaptor.

DO NOT CHARGE CONTINUOUSL Y FOR 24 HOURS OR MORE. DOING SO

DETERIORATE.

4. If the operating time decreases drastically even when the rechargeable nickel­cadmium batteries are properly recharged, purchase a new set of rechargeable
nickel-cadmium batteries.

5. When charging for the first time or after a long time, playing time may be reduced.
In this case, charge and discharge the batteries several times.

HANDLING COMPACT DISCS

This unit is designed to play only compact disc bearing the identification logo below.
Other disc may not conform to the CD standard and may not play properly.

• Dirty, scratched or warped disc may cause
skipping or noise.

• Handle the disc only by the edges. To keep
clean, do not touch its surface.

• Discs should be stored in their cases after use
to avoid serious scratches.

• Do not expose disc to direct sunlight, high
humidity, high temperatures or dust etc. Pro­longed exposure to extreme temperatures can
warp the disc.

• Do not stick or write anything on either side of
disc. Sharp writing instruments, or the inks
used in some felttip pens, may damage its
surface.

Remove the disc

Hold the edge and gently press the centre pivot
as illustrated, to pick up the disc.
CAUTION:
Wait for the disc to stop rotating before pressing
the OPEN button.
Note: This unit can play 3" (8cm) single CD's
without an adaptor. Do not use a CD single
adaptor for these discs.

CLEANING DISCS

• Finger prints should be carefully wiped from
the surface of disc with a soft cloth. Unlike
conventional records, compact discs have no
grooves to collect dust and microscopic debris,
so gently wiping them with a soft cloth should
remove most particles. Wipe in a straight
motion from the center to the edge.

• Never use thinner, benzine, record cleaner or
anti-static spray on a compact disc. Such
chemicals can damage its plastic surface.

USING ANTI-SHOCK AND SKIP FREE PROTECTION FEATURE

PRODUCT SPECIFICATIONS

Note the " " indicator appears on display as being empty when the player first
activated. It immediately begins to store sound data in memory bank, the indicator

appears to be "

When the laser loses tracking due to mechanical shock, the data stream into the
memory is interrupted but the data output from the memory buffer continues, so
the sound is not interrupted. As the data is read from the memory, the indicator

changes from "

Once the laser locks again on the CD track, the data stream is fed to the memory
and joined to the previous data (see indicator changes) at higher speed, this provides
higher level shock protection than the traditional one.

CAUTION

If the unit is subject to excessive and continuous repeated shocks than expected,
it will cause sound skip. Also note the "

NOTES

• When the "ANTI-SHOCK" is operating, the battery consumption is higher
because the disc rotates faster than normal and also the memory circuitry is
activated.

• When the digital anti-skip function is switched "ON" or "OFF", the sound will be
interrupted, and it is normal.

• Remember that condition such as dirty, scratched or warped discs may cause
skipping or noise thereby affecting performance of "ANTI-SHOCK" system.
