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 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.

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.
