PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
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.
sCaution: Invisible laser radiation when
open and interlocks defeated avoid
exposure to beam.
sAdvarsel: Usynlig laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgå udsættelse for stråling.
VAROITUS!
Laiteen Käyttäminen muulla kuin tässä käyttöohjeessa
mainitulla tavalla saataa 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 herin may result in
hazardous radiation exposure.
ATTENTION
L’utillisation 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
(VED0375-TN)
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
right figure.

Method : Play back the test tape and adjust SFRs so that the
output level of the test point is 245mV.
5. REC/PB Frequency Response Adjustment
Settings : • Test tape : TTA–602
• Test point : TP8 (Lch), TP9 (Rch)
• Input signal : 1kHz / 10kHz (LINE IN)
• Adjustment location : SFR351 (Lch)
SFR352 (Rch)
Method : Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the TP8,
TP9 becomes 0dB (17mV). Record and play back the
1kHz and 10kHz signals and adjust SFRs so that the
output of the 10kHz signals becomes 0dB ± 0.5dB
with respect to that of the 1kHz signal.
6. REC/PB Frequency Response Check

Method : Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at the TP8,
TP9 becomes 0dB (17mV). Record and play back the
1kHz and 10kHz signals and check that the output of
the 10kHz signals is 0dB ± 2dB with respect to that of

Method : Apply a 1kHz signal and REC mode. Then adjust
OSC attenuator so that the output level at TP8, TP9
becomes 0dB (170mV). Record and play back the
1kHz signals and adjust SFRs so that the output
becomes 0dB ± 0.5dB.
Method : Apply a 1kHz signal and REC mode. Then adjust

CD TEST MODE
1. How to activate CD Test Mode
Insert the AC plug while pressing the “Enter” button.
FL display is fully illuminated and test mode will be
activated. Insert the test disc and operate the test
mode following the control method as shown below.
Note:If no CD was inserted, it displays “No Disc”
and cannot be operated.
2. How to cancel CD Test Mode
Either one of the following operations will cancel the
CD test mode.
• Disconnect the AC plug.
• Press “Function” button.
• Press “Power” button.
• Press “Band” button.
3. CD Test Mode functions
When test mode is activated, the following mode functions can be used by pressing the operation keys.

* Note 1 : When pressing the r or t keys, take care to avoid damage to the gears. Because the sled motor is
activated when the r or t keys are pressed, even when the pick-up is at outermost or innermost
track. The sled operation is not as normal and moves outermost track with r button and innermost
track with t button
* Note 2 : There are cases when the tracking servo cannot be locked owing to the protection circuit being operated
when heat builds up in the driver IC if the focus search is operated continually for more than 10 minutes.
In these case, the power supply should be switched off for an hour until heat has been reduced and then
re-start.
