Adjustment
Terminal Unit Parts
ANT Operation Tuning Set the following adjustment values to the
panel control transceiver by turning the Tuning control.
(Front) ∗ When the transceiver is shipped, the SWR
adjustment value is different from that which
is stated in this manual, as SWR protection
adjustment is performed at production.
Although there is a difference in the numerical
value, this does not pose a problem, as the
adjustment value provided in this manual is the
mean value.
Adjustment value: 66
Adjustment value:
120
By turning the Tuning
control, adjust the
modulation wave
until it becomes the
square wave.
