DCS Tx Deviation Adjustment 

(

DCS DEV

)

H

 Press the 

V/M

 button, then transmit and adjust the de-

viation for 0.6 kHz (±0.1 kHz) by rotating the 

DIAL

, then

press the 

V/M

 button. Rotate the 

DIAL

 to select the next

setting.

NOTE: The next step depends on the geographical "version" of

the transceiver being aligned:

EXP Version: Alignment of the "SUB Band " follows (see

page 18.)

USA Version: Press the BAND button to activate the

222 MHz band internal alignment routine. In this case,
the alignment frequency will automatically be set to
222.000 MHz.
