Cautions
Note related to transportation and movement Before transporting or moving this unit, carry out the following operation. 1. Set the POWER key to ON without loading a Mini Disc. ÷ Check that no disc is present in the unit. 2. Wait a few seconds and verify that the display shown appear. 3. Set the POWER key to OFF.
Beware of condensation
When water vapor comes into contact with the surface of cold material, water drops are produced. If condensation occurs, correct operation may not be possible, or the unit may not function correctly. This is not a malfunction, however, the unit should be dried. (To do this, turn the POWER switch ON and leave the unit as it is for several hours.)
Be especially careful in the following conditions :
When the unit is brought from a cold place to a warm place, and there is a large temperature difference. When a heater starts operating. When the unit is brought from an air-conditioned place to a place of high temperature with high humidity. When there is a large difference between the internal temperature of the unit and the ambient temperature, or in conditions where condensation occurs easily.

CIRCUIT DESCRIPTION
4-7 Precaution on use of test mode
( An erasure prevention control is not detected in the test mode. Therefore, when the recording laser power mode such as continuous recording mode and traverse adjustment mode is entered, the contents of the existing recording are erased irrespective of the control position. Be careful not to enter the continuous recording mode and traverse adjustment mode when using a disc, containing the data that should not be erased, in the test mode. 5) Take care that VC and GND (ground) are not connected on the oscilloscope when two or more signals are monitored on the oscilloscope. (VC and GND are short-circuited in this case.) Note : The "#" display on the screen indicates an arbitrary figure.
5-4 Creating the recordable continuous recording disc
This disc is used for focus bias adjustment and error rate confirmation. How to create the recordable continuous recording disc is described below. Insert a commercial recordable disc (blank disc). Turn the JOG DIAL to display "CREC MODE." Press the ENTER key to display "CREC IN". Turn the JOG DIAL (CW ) to display "CREC-MID". After pressed the ENTER key, a display indicates "CREC(0300)" and the recording begins. 6. Terminate the recording within five minutes. 7. Press the DELETE key to stop the recording. 8. Press the EJECT key to take out the recordable disc. As a result, a continuously recorded disc can be created for focus bias adjustment and error rate confirmation. Note : Take care that no vibration is applied during continuous recording. 1. 2. 3. 4. 5.
5. Electrical adjustment
5-1 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.
5-2 Precaution on handling of Optical pick-up (KMS260A)
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. When removing the flexible board from the connector, make a solder bridge in advance, then remove the board. Be careful not to remove the solder bridge before inserting the connector. Moreover, take careful measures against electrostatic destruction. The flexible board is cut easily. Handle the flexible board with care. Pick-up
