COM Window and Tuning
Communication frequencies are selected with the
tuning cursor in the standby COM frequency field,
and using the large and small left knobs to dial in
the desired frequency. The standby frequency always
appears below the active frequency. The active fre-
quency is the frequency currently in use for transmit
and receive operations.
Tuning cursor in the COM window. Use the
small and large left knobs to dial in the
desired standby frequency.
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 pro-
cess is referred to as “auto-tuning”. Once a frequency
is selected in the standby field, it may be transferred
to the active frequency by pressing the COM flip-flop
key.
Once the standby frequency is selected, use
the COM flip-flop key to make the frequency
active for transmit and receive operations.
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 automatically
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.
