from the dispatcher. A short tone sounds when this key is pressed.
Contact your system operator for more information on the operation of
this switch.
Transmit Inhibit
The Transmit Inhibit feature prevents the transmitter from turning on
if the party you are calling is busy with another call. When the transmitter
is disabled by this feature, the intercept tone also sounds and “TX
INHIB” appears in the display. This feature is programmed by your
system operator on Multi-Net systems only.
To make another call attempt when the transmitter has been disabled
by this feature, the push-to-talk switch must be released and then pressed
again. However, since a 5-second time period must expire, you may want
to wait a few seconds before making another call attempt. One use of this
feature is to provide an audible indication that the party you are calling is
busy.
Priority Calls
Your transceiver can be programmed so that certain incoming calls
have priority over other calls you may be receiving. Therefore, if a higher
priority call is detected while you are listening to another call, the current
call is immediately dropped and the priority call is received.
If a first priority call is received, “RX PRI1” is displayed, and if a
second priority call is received, “RX PRI2” is displayed. A priority 1
message can interrupt a priority 2 message. To turn off the priority indica-
tion, press any key except backlight. Priority calls occur only on Multi-
Net and LTR systems, and they are received regardless of the group that
is selected (as long as the system programmed for those calls is selected
or scanned).
Keypad Disable
If you are having problems with front-panel keys being accidentally
pressed, such as when the transceiver is carried on a belt, the keypad can
