2. An erasure prevention control is not detected in the test
mode. Be careful not to enter the continuous recording
mode using a disc containing the data that should not be
erased.
3. Do not record continuously for more than five minutes.
4. Take care that no vibration is applied during continuous
recording.
8. Electrical adjustment
8-1 Precaution during confirmation of Laser Diode
emission
During adjustment, do not view the emission of a laser
diode from just above for confirmation. This may
damage your eyes.
8-2 Precaution on handling of Optical pick-up
(KMS-260B)
The laser diode in an optical pick-up is easy to be
subject to electrostatic destruction. Therefore, solder-
bridge the laser tap on the flexible board when handling
the optical pick-up.
