3 Handling Precautions For Traverse Deck (Optical
Pickup)
The laser diode in the traverse deck (optical pickup) may break down due to potential caused by static electricity of clothes or
human body. So, be careful of electrostatic breakdown during repair of the traverse deck (optical pickup).
human body. So, be careful of electrostatic breakdown 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 is inserted into flexible board (FFC board).(Fig.1)
3. Take care not to apply excessive stress to the flexible board (FFC board). When removing or connecting the short pin, finish

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 adjusted.
· Grounding for electrostatic breakdown prevention
1. Human body grounding (Fig.2)
Use the anti-static wrist strap to discharge the static electricity from your body.
2. Work table grounding (Fig.2)

SC-EN17E / SC-EN17EB / SC-EN17EG / SC-EN17GCS / SC-EN17GD
Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is place, and ground
the sheet.
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).
the traverse deck (optical pickup).
Caution when replacing the Traverse Deck
The traverse deck 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 connections.

4 Precaution of Laser Diode
Caution :
This product utilizes a laser diode with the unit turned "ON", invisible laser radiation is emitted from the pick up lens.
Wavelength : 780 nm
Maximum output radiation power from pick up : 100 µW/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 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.
