[RF GAIN] : Fully clockwise
Connect the RF Signal Generator to the “HF/50
MHz” ANT jack, then set the frequency to
14.200 MHz.
Connect the RF millivoltmeter to TP6501 on the
SCP Unit.
Adjust T6507, T6506 and T6504 on the SCP
Unit in succession several times for maximum
deflection on the RF millivoltmeter.
Set the RF Signal Generator output level to +36
dBµ at the 14.200 MHz.
Press the assigned [A], [B] or [C] key to activate
the SCOPE function.
