PROTECTION OF EYES FROM LASER
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.
m Caution: Invisible taser radiation when
open and interlocks defeated avoid expo- sure to beam.
m Advarsel: Usynlig !aserstraling ved abning, nar sikkerhedsafbrydere er ude af funktion.
Undga udseettelse for straling.
VAROITUS! Laiteen Kayttaminen muulla kuin tassa kayttéohjeessa mainit- ulla tavalla saattaa altistaa kayt-tajan turvallisuusluokan 1 ylittavalie nakymattémalle lasersateilylle.
VARNING! Om apparaten anvands pa annat satt 4n vad som specificeras i denna bruksanvisning, kan anvandaren utsattas fér osynlig
laserstralning, som éverskrider gransen fér laserklass 1.
Precaution to replace Optical block
(KSS — 210A)
Body or clothes electrostatic potential could
ruin laser diode in the optical block. Be sure to
ground body and workbench, and make sure the
clothes do not touch the diode.
1) After the connection, remove the solder
shown in the right figure.

. Set SFR103 (TG) to minimum.
2. Connect an oscilloscope to test points TP6 (TRIN) and
TP8 (VREF).
. Turn on the power switch.
. Insert test disc TCD-782 (YEDS-18) and press the PLAY
(>) button.
. Press the FF key repeatedly.
. Adjust SFR301 (TB) so that the waveform on the
oscilloscope is vertically symmetrical as shown in the
figure below.
. After the adjustment is completed, remove the ground
lead wires from the terminals.

© Tracking Gain Adjustment
A servo analyzer is necessary in order to perform this
adjustment exactly. However, this gain has a margin, so
even if it is slightly off, there is no problem. Therfore,
do not perform this adjustment. Focus/ tracking gain
determines the pick- up follow- up (vertical and
horizontal) relative to mechanical noise and mechinical
shock when 2-axis device operates. However,as these
gains are reciprocated, the adjustment is performed so
that both gains are satisfied.
@ When gain is raised, the noise increases when the 2-
axis device opearates.
@ When gain is lowered, it is more susceptible to
mechanical shock and skipping occurs more easily.
When the gain adjustment is not satisfied, tye symptoms
below appear.

@ Sound is interrupted during

— Simple adjustment —
Note: Since the adjustment cannot be performed exactly,
remember the positions of the controls before the
adjustment and compare the adjusted position and
the original position.
lf the difference is a little, return the control to the
original position.

1, Keep the set horizontal. (If the set is not kept
horizontally, this adjustment cannot be performed due to
the gravity against the 2-axis device.)
2. Insert test disc TCD-782 (YEDS-18) and play back the second composition.
