1 - COM

Communication frequencies are selected with the tuning cursor in the standby COM frequency fi eld, and 

using the small and large left knobs to dial in the desired frequency. The standby frequency always appears 
below the active frequency. The active frequency is the frequency currently in use for transmit and receive 
operations.

A frequency may also be quickly selected from the database by simply highlighting the desired frequency 

on any of the main pages and pressing ENT. This process is referred to as “auto-tuning”. Once a frequency is 
selected in the standby fi eld, it may be transferred to the active frequency by pressing the COM fl ip-fl op key. 

While receiving a station, an “RX” indication appears in the upper right corner of the COM 

window — to the immediate right of “COM”. A “TX” indication appears at this location while you are trans-
mitting.

NOTE: The tuning cursor normally appears in the COM window, unless placed in the VLOC window 
by pressing the small left knob. When the tuning cursor is in the VLOC window, it au to mat i cal ly 
returns to the COM window after 30 seconds of inactivity. The active frequency in either window 
cannot be accessed directly — only the standby frequency is highlighted by the tuning cursor.
