PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
Solder
CD PICK-UP ASSY P.C.B
This set employs laser. Therefore, be sure to follow carefully the
instructions below when servicing.
WARNING!
WHEN SERVICING, DO NOT APPROACH THE LASER EXIT
WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO
CONFIRM LASER BEAM EMISSION. BE SURE TO OBSERVE
FROM A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL
PICK-UP BLOCK.
Caution: Invisible laser radiation when
open and interlocks defeated avoid exposure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa mainitulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylittävälle näkymättömälle lasersäteilylle.
VARNING!
Om apparaten används på annat sätt än vad som specificeras i
denna bruksanvising, kan användaren utsättas för osynling
laserstrålning, som överskrider gränsen för laserklass 1.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
ATTENTION
L'utilisation de commandes, réglages ou procédures autres que
ceux spécifiés peut entraîner une dangereuse exposition aux
radiations.
ADVARSEL!
Usynlig laserståling ved åbning, når sikkerhedsafbrydereer ude
af funktion. Undgå udsættelse for stråling.

Precaution to replace Optical block
Body or clothes electrostatic potential could ruin
laser diode in the optical block. Be sure ground
body and workbench, and use care the clothes
do not touch the diode.
1) After the connection, remove solder shown in
the right figure.

5. DC balance/ MONO Distortion Adjustment
Settings: • Test point: TP2, TP3
• Adjustment location: IFT101
• Input level: 60 dB
Method: Set to FM 98.0 MHz and adjust IFT101 so that the
voltage between TP2 and TP3 becomes 0 V ± 0.02 V.
6. AM tuning Adjustment
Settings: • Adjustment location: SFR102
Method: Make setup for AM 1400 kHz. Adjust SFR102 so that
the machine performs Auto Stop when 50 ± 2 dB is
input.
* Confirm that TP4 is “L” at this time.
7. FM tuning Adjustment
Settings: • Adjustment location: SFR101
Method: Make setup for FM 98.0 MHz. Adjust SFR101 so that
the machine performs Auto Stop when 33 ± 2 dB is
input.
* Confirm that TP4 is “L” at this time.
<TAPE SECTION>
8. Tape Speed Adjustment (DECK1)
Settings: • Test tape: TTA-100
• Adjustment location: SFR751
Method: Play back the test tape with DECK1 and adjust SFR751
so that the output frequency is 3000 Hz. After the adjustment, check that the frequency of DECK2 is 3000
± 45 Hz.
9. Azimuth Adjustment (DECK1, DECK2)
Settings: • Test tape: TTA-320
• Adjustment location:
Head azimuth adjustment screw
Method: Play back the 10 kHz signal of test tape and adjust
screw so that the output becomes maximum.
10. Bias OSC Fequency Adjustment
Settings:• Test tape: TTA-601
• Adjustment location: L301
• Test point: TP301
Method: Set to the REC mode. Adjust L301 so that thr fre-
quency counter of the test point becomes 71.5 kHz ±
0.5 kHz
