15、XPOSURE. n Use of Caution Labels 7 SA-PM19E / SA-PM19EB / SA-PM19EG The 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 (op

16、tical pickup). l Handling of CD traverse deck (optical pickup) 1. Do 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

17、 build-up to prevent damage to the laser diode (Fig 1). 3. Take care not to apply excessive stress to the flexible board (FPC board). 4. Donotturnthevariableresistor(laserpower adjustment). It has already been adjusted. Fig 1 l Grounding for electrostatic breakdown prevention 1. Human body grounding

18、 (Fig 2) Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding (Fig 2) Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet. Caution : The static electricity of your

19、 clothes will not be grounded through the wrist strap. So, take care 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

20、sure to remove the solder from the short point before making connections. 6 Handling Precautions For Traverse Deck 8 SA-PM19E / SA-PM19EB / SA-PM19EG 7 Accessories AC mains lead (For EB only) ACmains lead (For E & EG only) FM indoor antenna AM loop antenna Remote control transmitter Antenna plug ada
