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.
