CONVENTIONAL FEATURES

A conventional system must be selected to enable monitoring. If the microphone is taken off-hook with an LTR-Net or LTR system selected, scanning halts (unless off-hook detection is disabled) but monitoring is not selected.

Transmit Disable On Busy

The Transmit Disable On Busy feature automatically disables the transmitter if the selected group (channel) is busy and it has not been monitored when the PTT switch is pressed. When the trans- mitter is disabled by this feature, the busy tone sounds briefly and “DSBL BSY” is indicated on the lower line of the display.

While the PTT switch is pressed, the receiver is enabled so that activity on the channel can be monitored. The PTT switch must be released and then pressed again to make another call attempt. Occa- sionally, a busy condition may be detected even though no one is talking. To key the transmitter in this case, release the PTT switch and then immediately press it again.

There is also a programmable option with this feature to allow transmitting with a busy channel if the correct Call Guard signal is detected. The Transmit Disable On Busy feature is enabled or disabled on each conventional group by dealer programming. If this feature is disabled or if monitoring has been performed by taking the microphone off-hook, the transmitter keys even if the group is busy.

Talk-Around

Normally, all transmissions go through a repeater which usually increases range because the repeater transmits at a higher power level and has a higher antenna. However, this means that if you are out of radio range of the repeater, you cannot talk to anyone even if the mobile you are calling is only a short distance away. To allow communication if this occurs, talk-around groups can be programmed which enable direct mobile-to-mobile communication without going through a repeater.
