While setting the squelch, appears fol-
lowed by
a blanked
segment (inverse of the vol-
ume setting display) on the bargraph
meter, indicating the present squelch level. Be-
low the third segment (approx.), the
or
UHF
LED glows green, indicating the squelch is
open. To set the squelch:
After setting the volume to a comfortable
level, if a signal is present, turn the
DIAL
to an
empty channel (no signal, or
only
noise).
Press and then just to the point
where background noise is silenced and the
LED turns off. (If the squelch is set to a higher
level, sensitivity to weak signals is reduced.)
Now, whenever a signal is received strong
enough to open the squelch, the
VHF
or
UHF
indicator for the appropriate band glows green.
Note that while receiving, one or more
graph segments may appear along the bottom of
the display, indicating received signal strength.
This is not affected by the squelch,
so even
squelched signals can give some indication. If
several bargraph segments appear while the
squelch is closed, try reducing the squelch set-
ting (if you want to hear weak signals).
In non-European versions, the monitor
switch (the button below the
P
T
T )
opens the
squelch so you can check for weak signals, and
adjust volume independently.
Frequency Selection Modes
VFO
Mode
This mode is for tuning or scanning the band
when looking for a channel on which to operate,
when you don't have a specific frequency in
mind. In this mode, the
DIAL
knob and arrow
keys each tune the band in the selected step size,
or in 1-MHz steps, and the scanning function
tunes in the selected step size. The FT-51R has
two independent VFOs, A and B, for the main
channel, and two more for the sub channel.
These are toggled by pressing
when receiv-
ing on either VFO. An A or B to the upper-left of
the frequency shows which VFO is currently
selected.
Mode
This mode is mainly for operating on specific
channels known in advance (and stored in the
memories). For example, after storing the fre-
quencies
of
your local repeaters, you can confine
operation to those channels by selecting the
