l Precaution of Laser Diode

CAUTION:
' Wave length: 780 nm

Maximum'output radiation power from pick up: 100 pWNDE

This product utilizes a. laser diode with the unit tumed"'on"

. invisible laser radiation is emitted from the pick up lens.

Laser radiation from the pick up unit is satety level, but be sure the followings:

1. Do not disassemble the 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.

ACHTUNG:

Wellenlange: 780 nm
Maximale strahlungsleistung der laserinhelt: 100 pWNDE

Dieses produkt enthélt eine laserdiode. lm elngeschalteten zustand wird unsichtbare laserstrahlung von der lasereinheit adgestrahit.

Die strahlung an der lasereinheit isl ungef'ahrllch, wenn tolgende punkte beachtet warden:

1. Die lasereinheit nicht zerlegen, da die strahlung an der freigelegten laserdiocle gefahriich ist.
2. Den werksseitig iustierten einstellregler der lasereinreit nicht verstellen.
3. Nicht mit optischen instrumenten in die fokussierltnse blioken.

4. Nlcht fiber Iangera zeit in die lokussierlinse blicken.

OThe voltage value and waveforms are the reference voltage of this
measured by DC electronic voltmeter (high impedance) and oscilloscope
on the basis of GND terminal (DC iN Jack). Accordingly, there may arise
some errors In the voltage values and waveforms depending upon the
internal impedance of the tester or measuring unit.

OThe parenthesized is the voltage for test disc (1kHz, L+Ft, 0 dB) in play
mode, and the other, for no disc in stop mode.

oAC adaptor is used for power supply.

clmportant safety notice:

Components identified by A mark have special characteristics important
for safety. Furthermore, special parts which have purposes of fire-
retardant (resistors), high-quality sound (capacitors), low-noise (resistors),
etc. are used. When replacing any of components, be sure to use only
manufactures specified parts shown in the parts list.

Caution!

IC and LSl are sensitive to static electricity.

Secondary trouble can be prevented by taking care during repair.
0 Cover the parts boxes made of plastics with aluminum foil.

0 Ground the soldering iron.

0 Put a conductive mat on the work table.

I Do not touch the pins of IC or LSl with fingers directly.
