operation is not complicated, but it is still possible to get lost, at least until
MK ‡U
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 (VOL control), and if necessary,
remove the battery pack and check that the contacts are clean. If all appears to be physi-
cally in order, recharge or replace the batteries.
Fortunately, the display itself 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 5 carefully. For example, if the frequency display changes unex-
pectedly when you transmit (or if "Err " appears), check for a small "+" or "–" at the upper
right-hand corner. Also, if only a few seemingly non-sensical digits appear, press [ T ] to
disable the tone squelch setting feature.
Attempting an illegal command (such as activating the tone squelch when the FTS-12 is
not installed), will cause two beeps to sound. If pressing a key appears to do nothing, first
check for a small "L" at the lower left, which indicates if the keypad is locked. If you see
this, press [ F ] + [ LOCK ] to unlock the keys. If the "L" is not there, press [ D/MR ] , which
will terminate any partially entered commands. If you still cannot enter data, check the
BUSY/TX indicator to see if it is red, indicating that the transceiver is transmitting. Re-
leasing 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 set the transceiver down while it is on, and then remember to set the
lock back off when you wish to enter data.
If none of these measures helps, contact your Yaesu Dealer for assistance.
