Tuning Methods
Throughout this manual, you will see references to sev-
eral different frequency setting methods. Each will be
particularly 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 NAV or
COM bands using the
DIAL
selector, the Keypad, or the scanner. The
FTA-310
has
two VFOs which are called VFO-A and VFO-B. Press
the [
SCAN
(
DW
)] key momentarily to switch between
VFO-A and VFO-B. You may set VFO-A to the NAV
band, and VFO-B to the COM band, if you like.
MR (Memory Recall)
The MR (Memory Recall)
mode of the
FTA-310
pro-
vides the user with the ability
to store and recall as many
as 150 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 30 for details on creating alpha/numeric labels.
BOOK (Pre-Programmed) Memories
The Book memories are pre-
programmed, either at the
factory or by your Dealer
(depending on your country’s
requirements), typically including the major COM
and NAV band station frequencies used in your area.
The Book memories can be changed by the user.
See page 44 for details.
WX (Weather Channel) Memories
(USA version only)
Ten Weather Channels are pre-programmed at the
factory. The
FTA-310
will
automatically scan this spe-
cial bank when it is selected
by the user.
