In Case of Problems
FT-712RH operation is not complicated, but it is still possible to get lost, at least
until you have had the chance to learn the various functions of the keypad and
display. If the display shows nothing at all, check the power switch, and the
power supply connections.
Fortunately, the display includes enough symbols and function indicators 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 6 carefully. For example, if the frequency
display changes unexpectedly when you transmit (or if 'Err' appears), check for a
small '+' or '-' near the upper right. Also, if only a few seemingly non-sensical
digits appear, press TONE to disable the tone squelch setting feature. If nothing
happens, press VOICE to disable the DVS-1 Digital Voice System (if it is
installed).
If pressing a key appears to do nothing, first check for "LOCK" at the lower left,
which indicates if the buttons are locked. If so, press [F]+LOCK to unlock the
keys. Otherwise, if "LOCK" is not displayed, press D/MR, which will terminate
any partially entered commands. If you still cannot enter data, check to see if
"ON AIR" is displayed, indicating that the transceiver is transmitting. Releasing
the PTT switch should return the set to receive. If still nothing happens, switch
the transceiver off, and then back on.
To avoid confusion resulting from inadvertent key presses, set the keypad lock
on (press [F]+LOCK) if you leave the transceiver unattended while it is on, and
then remember to set the lock back off when you wish to enter data.
