Tuning Methods
Throughout this manual, you will see references to sev-
eral different frequency setting methods. Each will be par-
ticularly useful in a particular operating situation, and they
are described below:
VFO
(
Variable Frequency Oscillator
)
The VFO is a “tuning
dial” system which allows
you to tune through the
AIR band and FM BC
band using the
DIAL selector, the Keypad, or the scan-
ner. To select these bands, press the key momen-
tarily.
MR
(
Memory Recall
)
The MR (Memory Re-
call) mode of the
VXA-
710
provides the user
with the ability to store
and recall as many as 68 channels in the radio’s main
memory bank. These memory channels may also be
labeled by you with an alpha/numeric name of up to 8
characters in length, to aid in quick identification of
the channel. See page 20 for details on creating alpha/
numeric labels.
