So, be careful of electrostatic break

9、down during repair of the traverse deck (optical pickup). Handling of 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. To prevent the breakdown of the laser diode, an antistatic shorting pin

10、 is inserted into the flexible board (FFC board). 3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish the job in as short time as possible. 4. Do not turn the variable resistor (laser power adjustment). It has already been a

11、djusted. Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place

12、, and ground the sheet. Caution : The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse deck (optical pickup). Caution when replacing the Traverse Deck The traverse deck has a short point shorted with solder to p

13、rotect the laser diode against electrostatics breakdown. Be sure to remove the solder from the short point before making connections. 7 SA-AK230E / SA-AK230EB / SA-AK230EG n Use of caution label 7 Precaution of Laser Diode Caution : This product utilizes a laser diode with the unit turned ON, invisi

Wavelength : 780 nm Maximum output radiation power from pick up : 100 W/VDE Laser radiation from pick up unit is safety level, but be sure the followings: 1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is

15、 dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4. Recommend not to look at pick up lens for a long time. ACHTUNG : Dieses Produkt enthlt eine Laserdiode. Im eingeschalteten Zustand wird unsi
