LTR-NET AND LTR FEATURES
Transmit Inhibit
The Transmit Inhibit feature prevents the transmitter from keying if
the mobile you are calling is busy with another call. When the transmitter
is disabled by this feature, the intercept tone sounds and “TX INHIB” is
displayed (see following illustration). To make another call attempt, the
PTT switch must be released and pressed again. However, you may want
to wait a few seconds before making another attempt because a timer
must time out before another attempt will be successful. A similar
Transmit Disable On Busy feature is available on conventional systems
(see page 50).
Priority Calls
Each LTR-Net and LTR group is programmed with a receive priority
number. If a call is detected on a group in the group scan list that has a
higher priority than the selected group, it is received (even if scanning is
not enabled). If another call is in progress when the higher priority call is
detected, the current call is immediately dropped. Some groups, such as
those used to make telephone calls, may be programmed as not interrupt-
ible to prevent other calls from interrupting a call in progress.
The system/group of the priority call is displayed while it is
received. The programming described on page 43 determines if the
change is temporary or permanent and if a response occurs on the last
selected or received system/group.
