1. Digital oscilloscope (100MHz)
2. AM Standard signal generator
3. FM Standard signal generator
4. Stereo modulator
5. Electric voltmeter
6. Digital tester
7. Tracking offset meter
8. Test Disc JVC :CTS-1000

EXTSH002-22P 1
Standard measuring conditions
Power supply voltage DC14.4V(11 to 16V)
Load impedance
Output Level
How to connect the extension cable for adjusting
The cardboard is cut in a suitable size.
uses for the insulation stand of mechanism.
Caution:
Be sure to attach the heat sink and rear
bracket onto the power amplifier IC and
regulator IC respectively, before supply
the power.
If voltage is applied without attaching
these parts, the power amplifier IC
and regulator IC will be destroyed
by heat.

20Kohm(2 Speakers connection)
Line out 2.0V (Vol. MAX)
Heat sink
(Attach the heat sink
using the two screws.)
Front chassis assembly
(Attach the front chassis assembly using the two screws.)
Standard volume position
Balance and Bass &Treble volume : lndication "0"
Loudness : OFF
Frequency Band
FM 87.5MHz to 107.9MHz
AM 530kHz to 1710kHz
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 antenna input. The loss of 6dB need not be considered
since direct reading of figures are applied in this working
standard.
