2.7 RECEIVE FREQUENCY SIMPLEX FUNCTION
The receive frequency simplex function allows you to quickly change the transmit
frequency, when operating on a split pair (repeater/semi-duplex mode), to the receive
frequency to allow direct communications. (For example, if you are transmitting on 42.000
MHz and receiving 42.555 MHz, press
FUNC,
then
UP
to transmit on 42.555 MHz. To
return to the split pair condition, you must recall the memory channel again. This is quickly
done by pressing
M.UP
for one step up, then back down one step with the
M.DN
key.)
2.8 KEYBOARD LOCKOUT FUNCTION
The keyboard can be locked out so that accidental pressing of keys does not change
frequency, etc., unknowingly to the operator. To lock the keyboard, press
FUNC
then
LOCK
.
This will disable all keyboard functions (except keyboard unlock) in the receive mode. The
DTMF function during transmit will not be affected. To unlock the keyboard, press and hold
the
LOCK
key for two seconds until the display indicates "UNLOCK".
2.9 VARIABLE FREQUENCY MODE FUNCTION
To enter variable frequency mode, press
RCL, 0,0,0
, then
ENTER
. The memory channel that
you were just in will still be valid but now you can manually adjust the frequency with the
M.UP, M.DN, UP
and
DN
keys. The
UP
and
DN
keys will make the frequency count up or
down in steps of 2.5 kHz. The
M.UP
and
M.DN
keys will make the frequency count up or
down in steps of 1 MHz. You can not change the label. The frequency in this mode cannot
be stored in memory. To exit this mode, recall one of the 120 memory channels (e.g.
RCL,
0,0,1
). Variable frequency mode is disabled when the internal entry disable jumper is set.
2.10 LED DISPLAY VARIABLE DIMMING MODE
1.
With the transceiver in normal operating mode, press the
UP
or
DN
keys to increase
or decrease the intensity of the LED display.
2.
Once maximum intensity of the display is achieved, the
UP
key no longer functions.
Conversely, once minimum intensity is reached, the DN key ceases to function.
2.11 90-SECOND TRANSMITTER TIME OUT FEATURE
A selectable 90-second transmitter time out feature is provided to prevent accidental
continuous transmission in the event of a faulty PTT switch. With this feature enabled, the
transceiver will stop transmitting after the PTT is engaged continuously for 90 seconds. The
timer is reset by releasing then re-engaging the PTT switch.
Press the
FUNC
then the
M.UP
key. Use the
M.UP
and
M.DN
keys to select 90 SEC, which
enables the feature, or NONE which disables it.
2.12 QUICK GUARD PROGRAMMING FEATURE
A quick download of any of the 120 memory positions to either of the guard memory
positions can be accomplished. Select the memory position whose contents you desire to
download to a guard memory. Select either GD1 or GD2 memory channel as desired. Press
FUNC,
then
7
. The guard memory channel will now contain all the same information as the
selected memory position. This feature is disabled when guard jumper (J15, pins 1 and 2 on
the MCU board) is removed.
