An erasure prevention control is not detected in the testmode. Be careful not to enter the continuous recordingmode using a disc containing the data that should not beerased.4. Do not record continuously for more than five minutes.5. Take care that no vibration is applied during continuousrecording.2-5 Other key functionNote : An erasure prevention control is not detected in thetest mode. Notice that recording is performed irrespectiveof the erasure prevention control position when the REC keyis pressed.2-6 Precaution on use of test mode An erasure prevention control is not detected in the testmode. Therefore, when the recording laser power modesuch as continuous recording mode and traverse adjust-ment mode is entered, the contents of the existingrecording are erased irrespective of the control position.Be careful not to enter the continuous recording modeand traverse adjustment mode when using a disc, con-taining the data that should not be erased, in the testmode.3. Electrical adjustment3-1 Precaution during confirmation of Laser DiodeemissionDuring adjustment, do not view the emission of a laser diodefrom just above for confirmation. This may damage youreyes.3-2 Precaution on handling of Optical pick-up(KMS-260A)The laser diode in an optical pick-up is easy to be subject toelectrostatic destruction. Therefore, solder-bridge the lasertap on the flexible board when handling the optical pick-up.When removing the flexible board from the connector, makea solder bridge in advance, then remove the board. Becareful not to remove the solder bridge before inserting theconnector. Moreover, take careful measures against elec-trostatic destruction. The flexible board is cut easily. Han-dle the flexible board with care.3-3 Precaution during adjustment1) Perform the adjustment and confirmation marked with“O” in the order shown in the table when the parts beloware replaced.Function Description3Plays back continuously when this key is pressed duringstop.
