PRECAUTION
1.1 Safety Precautions
!Burrs formed during molding may be left over on some parts of the chassis. Therefore,
pay attention to such burrs in the case of preforming repair of this system.

(No.MA287)1-5
1.2 Important for laser products
1.CLASS 1 LASER PRODUCT
2.CAUTION :
(For U.S.A.) Visible and/or invisible class II laser radiation
when open. Do not stare into beam.
(Others) Visible and/or invisible class 1M laser radiation
when open. Do not view directly with optical instruments.
3.CAUTION : Visible and/or invisible laser radiation when
open and inter lock failed or defeated. Avoid direct
exposure to beam.
4.CAUTION : This laser product uses visible and/or invisible
laser radiation and is equipped with safety switches which
prevent emission of radiation when the drawer is open and
the safety interlocks have failed or are defeated. It is
dangerous to defeat the safety switches.
5.CAUTION : If safety switches malfunction, the laser is able
to function.
6.CAUTION : Use of controls, adjustments or performance of
procedures other than those specified here in may result in
hazardous radiation exposure.
REPRODUCTION AND POSITION OF LABELS and PRINT
!Please use enough caution not to
see the beam directly or touch it
in case of an adjustment or operation
check.

ADJUSTMENT
4.1 Test instruments required for adjustment
(1) Digital oscilloscope (100MHz)
(2) Electric voltmeter
(3) Digital tester
(4) Tracking offset meter
(5) Test Disc JVC: CTS-1000
(6) Extension cable for check
EXTCD001-26P ×1
4.2 Standard volume position
Balance and Bass & Treble volume : Indication "0"
Loudness : OFF
4.3 Dummy load
Exclusive dummy load should be used for AM, and FM. For FM
dummy load, there is a loss of 6dB between SSG output and an-
tenna input. The loss of 6dB need not be considered since direct
reading of figures are applied in this working standard.
4.4 Standard measuring conditions
Power supply voltage : DC14.4V(10.5 - 16V)
Load impedance : 20KΩ(2 Speakers connection)
Output Level : Line out 2.0V (Vol. MAX)
4.5 How to connect the extension cable for adjustment
CAUTION :
Be sure to attach the heat sink and rear bracket onto the
power amplifier and regulator respectively, before supply the
power.
If voltage is applied without attaching those parts, the power
amplifier IC and regulator IC will be destroyed by heat.
