In Case of
Problems
The basic features of this transceiver are not complicated, but it is still
possible to get lost, at least until you have had the chance to learn all
of the functions of the keypad and display. If the display shows r1othing
at all, check the power switch (VOL control), and if necessary, remove
the battery pack and check that the contacts are clean. If all appears
to be physically in order, recharge or replace the batteries.
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 worth-
while to study the display diagram on page 7 carefully. for example, if
the frequency display changes unexpectedly when you transmit (or if
'Err' appears), check for a small
'+'
or
1
-
1
along the top of the display
(just right of center), indicating that repeater shift is active. Also, if
only a few seemingly non-sensical digits appear, try switch.ing the set off
and back on to clear any special display modes, such as tone squelch,
repeater offset, channel step or DTMF memory setting.
Most illegal commands will cause two beeps to sound. If pressing a key
appears to do nothing, first check for a small "Ptt" or an "L" in reverse
type at the lower left, which indicates the Ptt or keypad is locked. If so,
press F/M and then PTT LOCK(9) or LOCK(6) to unlock the PTT switch
or keys. If the "Ptt" or "L" is not there, press the f/M or CALL key,
which will terminate many partially entered commands. If you still
cannot e11ter data, check the TX indicator to see if it is red or orange,
indicating
tl~iat
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.
If you find the stored data is definitely non-sensical or far from what
you want, try the System Reset procedure described on the previous
page.
To avoid confusion resulting from inadvertent key presses, set the
keypad lock on '[press F/M and LOCK(6)] if you set the transceiver down
while it is on, and then remember to set the lock back off when you wish
to enter data.
