When the unit is turned on: n Use of caution label (Except for U.S.A.) 5 Precaution of Laser Diode CAUTION: 1. Do not look directly into the pick up lens. 2. Do

11、 not use optical instruments to look at the pick up lens. 3. Do not adjust the preset variable resistor on the pickup lens. 4. Do not disassemble the optical pick up unit. 5. If the optical pick up is replaced, use the manufacturers specified replacement pick up only. 6. Use of control or adjustment

12、s or performance of procedures other than those specified herein may result in hazardous radiation exposure. CAUTION! THIS PRODUCT UTILIZES A LASER.

13、he laser diode in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup). l Handling of CD traverse deck (optical pickup) 1. Do

14、not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive to electrical shock. 2. The short land between the No.4 (LD) and No.5 (GND) pins on the flexible board (FFC) is shorted with a solder build-up to prevent damage to the laser diode (Fig 1). 3. Take care

15、not to apply excessive stress to the flexible board (FPC board). 4. Donotturnthevariableresistor(laserpower adjustment). It has already been adjusted.

Caution : The static electricity of your clothes will not be grounded through the wrist strap. So, take care

17、not to let your clothes touch the traverse deck (optical pickup). Fig 2 Caution when Replacing the Optical Pickup : The traverse has a short point shorted with solder to protect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connecti

Memory is not affected by turning off the power or unplugging the socket. Be sure to clear memory after repair is completed. 3. Press STOPn/-DEMO” button. A symb

24、ol of self-diagnostic is indicated on the display if an error is found. If several errors are found, a respective indication is displayed when STOPn/-DEMO button is pressing repeatedly. (e.g. H01 CD F15 F01) If no error is found, only T indication is displayed and remains unchange even if STOPn/-DEM

25、O button is pressed. 11.3. Displaying Self-Diagnostic Results (H01, H02, H03, F01, F02) 1. Enter the self-diagnostic mode, following the instructions described in 11.1.1 Setting of the Self-Diagnostic Mode (Test Mode). 2. Insert a normal-positioned music tape with erase prevention niches on both Sid

26、es A and B. Press TAPE button to activate the TPS operation so that the tape automatically stops at an interval between music selections. 3. Press STOPn/-DEMO and TAPE buttons together on the remote controller. (Recording does not start.) 4. Then, insert a Cr02-positioned blank cassette tape with an

27、 erase prevention niche of Side A or B set to the left side. 5. Press /FF/ button. The tape will be forwarded and automatically stop after two seconds. 6. Remove the cassette tape, and set the other side. 7. Press /REW/ button. The tape will be rewound and automatically stops after two seconds. 8. P

28、ress STOPn/-DEMO button on the unit. If an error is found, a self-diagnostic key appears on the display. If several errors are found, the display shows these keys when STOPn/-DEMO button is pressed repeatedly. (Ex.: H01 - H02 - F01 - H01) If no error is found, only the message, “T” appears on the di
