LTR AND CONVENTIONAL MODES

General

Each selectable system can be programmed for LTR or conventional operation by your system operator. The type or types of operation that are programmed in your transceiver are determined by the type of radio equipment being used in your radio system. The differences in operation are described in the following information and elsewhere in this manual as required.

LTR Operation

The LTR mode provides automatic channel selection (trunking) and monitoring before transmitting. In addition, special tones and display messages indicate busy and out-of-range conditions. Selecting a system selects a collection of groups and other information such as fixed priority receive ID codes. Selecting a group selects a transmit and receive ID code and other information which controls the mobile or mobiles being called and what calls are received. LTR features are described starting on page 40.

Conventional Operation

In the conventional mode, selecting a system selects a collection of channels and other information unique to those channels. Selecting a group selects the specific channel and also squelch coding (if any) used on that channel. Conventional features are described starting on page 44.

There are no tones or messages to indicate busy or out-of-range conditions in this mode. A busy channel (group) is detected manually or automatically as described in the following information. An out-of-range condition cannot be detected automatically but may exist if you cannot get a response to any of your messages. Refer to “Operation At Extended Range” on page 54 for more information.
