LTR FEATURES

NOTE: Other LTR features are described starting on page 45.

Standard Group Calls

Standard group calls are between two mobiles or between a mobile and a control station. To place these calls in the LTR or LTR-Net mode, simply select the desired group and press the PTT switch (no number is dialed). The procedure for placing and receiving these calls is described starting on page 27.

Telephone Calls

Telephone calls allow you to place and receive calls over the public telephone system using your transceiver. LTR and LTR-Net telephone calls are described starting on page 30.

CONVENTIONAL FEATURES

Squelch Adjust

This function sets the squelch level used for conventional calls.

Since the squelch level for LTR-Net and LTR calls is preset and cannot be changed, this adjustment needs to be made only if you make conventional calls (refer to page 23 for more information on operating modes). Proceed as follows:

1.Select a conventional system and a group that is not busy. If the selected channel is programmed for Call Guard squelch, press the Monitor option switch (if programmed) to enable monitoring (see page 49).

2.Press FCN SQL to select the squelch adjust mode. The currently selected squelch level is then indicated by “SQ xxx” in the display.
