In Case
of
Problems
Don’t worry if you find FT-51R operation
somewhat complicated at first. You might find
yourself temporarily lost, at least until you have
had the chance to learn the various functions of
the display and keys. This section provides some
tips to help you navigate the various display and
key modes if you get stuck.
If the display shows nothing at all, check the
power switch, and if necessary, remove the bat-
tery pack and check that the contacts are clean. If
all appears to be physically in order, recharge
or
replace the batteries.
The state of the display tells a lot about the
current state of operation, and can take on many
different states. Fortunately, the display includes
many symbols and function indicators as well as
the User Help prompts to let you know what is
going on as long as power is applied, so it is well
worthwhile to study the display diagram on
page
8 carefully. For example, if two beeps
sound unexpectedly when you transmit, check
for a small
" + " or " - " near the top center of the
display, indicating that the operating frequency,
with the selected repeater shift, is resulting in an
out-of-band
Tx frequency.
Invalid key entries usually do nothing, and
no beep sounds. However, if the keys are locked,
nothing happens when you press a key for even
valid commands. Check for
(key lock),
( D
IA
L
lock) or
(
P
TT
lock) in the display.
If
you
see one of these, press the
LOCK
switch.
If you still cannot enter data, check to see if
either of the
VHF
or
UHF
LEDs are red, indicat-
ing the transmitter is activated. Releasing the
switch should return the set to receive. If
not, switch the transceiver off, and then back on.
If a does not appear in the 100’s-of-MHz
digit place on the
VHF band, or a on the UHF
band, or if the transceiver behaves strangely
when you try to tune, check for either
PAGE,
TPAGE
or
CODE
beneath the frequency display,
indicating that DTMF Paging, Trigger Paging or
Code Squelch is active with the code memory
display option. If
so,
press several times if
necessary, to clear these symbols and return the
frequency display to normal.
CODE
To avoid confusion resulting from inadver-
tent button presses, set the keypad lock on as
described on page
37 if you leave the transceiver
unattended while it is on. Remember to set the
lock back off when you wish to enter data.
