How to connect the extension cable for adjusting
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.
Standard volume position
Balance and Bass & Treble volume : lndication"0"
Loudness : OFF
Frequency Band
FM 87.5MHz ~ 107.9MHz
AM 530kHz ~ 1710kHz
The cardboard is cut in a suitable size.
uses for the insulation stand of mechanism.
CAUTION :
Be sure to attach the parts (Heat sink and rear bracket)
on the IC (Power amplifier IC321 and regulator IC901)
of a main board when supplying the power.
If voltage is applied without attaching those parts, the
power amplifier IC and regulator IC will be destroyed by heat.
