on the upper left corner on the “Alignment” window
previously.
U
To adjustment, double-click the left mouse button on
the “
DCS Ref. Modulation DCS Ref. Modulation DCS Ref. Modulation DCS Ref. Modulation DCS Ref. Modulation
” box to open the pop-up

kHz (±0.1 kHz) (for 25 kHz steps) deviation.
U
Press the “OK” box to lock in the new data.
Sensitivity
U
Set the transceiver to CH 4 via the “CH” box located
on the upper left corner on the “Alignment” window
previously.
U
Tune the RF signal generator to the same frequency as
the transceiver’s, then set the generator output level to
40 dBµ with ±3.0 kHz deviation @ 1 kHz tone modu-
lation.
U
To adjustment, double-click the left mouse button on
the “

” box to open the pop-up window,
then move the slide bar to adjust the best sensitivity;
ultimately, the radio should be aligned so that the RF
signal generator output level is –4 dBµ EMF or less
for 12 dB SINAD.
U
Press the “OK” box to lock in the new data.
U
To adjustment, double-click the left mouse button on
