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")

When the laser loses tracking due to mechanical shock, the data stream into the

the sound is not interrupted. As the data is read from the memory, the indicator

higher level shock protection than the traditional one.

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.
