“shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the
amplifier are used.
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
When the protection circuitry functions, the unit will not operate unless the power is first turned off
and then on again.

6 Handling Precautions For Traverse Deck
TOP PREVIOUS NEXT
Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive
The static electricity of your clothes will not be grounded through the wrist strap. So, take care
connections.
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 (optical pickup).
Handling of traverse deck (optical pickup)
1.
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.To connect to the PC
board, be sure to open by removing the solder build-up, and finishthe workquickly.
3. Take care not to apply excessive stress to the flexible board (FFC).
4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted.
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 placed, and ground the sheet.
Caution :
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 protect the laer diode against
electroststics breakdown. Be sure to remove the solder from the short point before making

Caution :
the pick up lens.
Wavelength : 780 nm
Maximum output radiation power from pick up : 100 µW/VDE
Laser radiation frompick 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.
CAUTION!
THIS PRODUCT UTILIZES A LASER.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.

The voltage value and waveforms are the reference voltage of this unit measured by DC
electronic voltmeter (high impedance) and oscilloscope on the basis of chassis. Accordingly,
there may arise some error in voltage values and waveformsdependingupon the internal
impedance of the tester or the measuring unit.
