• The Main band is selected.
Key
Function
MAIN Touch to select the Main band (Downlink frequency).
NOR
REV Change the tracking.
SUB Touch to select the Sub band (Uplink frequency).

Selecting NOR/REV tracking
Touching [NOR REV] changes the frequency
increment when rotating
MAIN DIAL
.
•NOR: Both downlink and uplink frequencies
simultaneously increase or decrease in the same
steps when you rotate
MAIN DIAL
.
•REV: The downlink frequency follows the tuning dial
rotation, however, the uplink frequency changes in
the reverse direction to the
MAIN DIAL
rotation, in
the same steps.
