I Precaution of Laser Diode

o For (P. PC) areas.

CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted irom the optical pickup lens when the unit is turned
on :

Do not look directly into the pickup lens.

Do not use optical instruments to look at the pickup lens.

Do not adjust the preset variable resistor on the optical pickup.

Do not disassemble the optical pickup unit.

It the optical pickup is replaced. use the manuiaclures speciiied replacement pickup only.

Use oi control or adjustments or perlormancc oi procedures other than those Spectlied herin may result in
hazardous radiation exposure.

a For (EB,EG,GC,GN) areas.

@WSAEJT

CAUTION: This product utilizes a laser diode with the unit turned "on, invrsible laser radiation is emitted irom the pickup lens.
Wave length: 780 nm
Maximum output radiation power lrom pickup: 100 pWNDE
Laser radiation item the pickup lens is salety level, but be sure the ioIIOwings:
1 00 not disassemble the optical pickup unit, since radiation from exposed laser diode is dangerous.
2 Do not adjust the variable resistor on the pickup unit. It was already adjusted.
3. Do not look at the locus lens using optical instruments.
4 Recommend not to look at pickup tens tor a long time.
ACHTUNG: Dieses Produkt enthalt eine Laserdiode. lm eingeschalteten Zustand wird unsichtbare Leserstranlung von der

Lasereinheit abgestrahit.

Wellenlange: 780 nm
Maximale Strahlungsleistung oer Lasereinheit: 100 uWNDE

Die Sirahtung an der Lasereinheit isi ungetahrlich. wenn iotgende Punkte beacntet warden:

Die Laseteinheit nicht zeriegen, da die Strahiung an der lreigelegten Laserdiode geiéhriich ist.
Den werkseitig jusiierten Einsteilregler der Lasereinhit nicht verslellen.

Nicht mit optischen lnstrumenten in die Fokussierlines blicken.

Nicht Liber tangere Zeii in die Fokussierlines biicken.

(Example) Follow the below steps when E- 1" is displayed.

(Cause: Focus balance (FBC) is set beyond the limit.)

0 Check it

(1) the wavetorm or voltage of the locus servo circuit ls correct.

(2) the optical pickup returns to the normal state by exchanging the traverse deck.

Follow the below steps when E - 4" Is displayed.

(Cause: Focus gain (FGC) is set beyond the limit.)

0 Check it

(1) the waveform or voltage oi the locus servo circuit ls correct.

(2) the locus coil ot the optical pickup is correct (around 15 ohms).

(3) the optical pickup returns to the normal state by exchanging the traverse deck.

Follow the below steps when E - F ls displayed.

(Cause :AII adjustments (TGC, FGC, TBC. FBC) are set beyond the limit.)

I Check it

(1) the optical pickup returns to the normal state by exchanging the traverse deck.

(2) the: wavelorrn or voltage ot the servo lCs (101m. 501) are correct.

Note:

It is not always necessary to exchange the traverse clock when an error message is displayed.
Be sure to check it the circuit is detective or not beloro exchanging the traverse deck.

Note:
It any other disc than the test disc (SZZPtOSllC) is used. an error message may be displayed. This is not a maltunction.

I Mesurements and Adjustments

Warning: This product uses a laser diode. Reter to caution statements on pages 2. 3.
ACHTUNG: 0 Die Iasereinheit nicht zerlegen.
0 Die lasereinheit dart nur gegen eine vorn herstetler spezilizierte einheit ausgetauscht warden.
