EFJohnson High Tier, LTR 98xx manual Talk-Around

CONVENTIONAL FEATURES

pressed. When the transmitter is disabled by this feature, the busy tone sounds briefly and “DSBL BSY” is indicated on the lower line of the display. The monitor mode (see preceding section) is enabled while the PTT switch is pressed so that activity on the channel can be monitored. However, it is not possible to access a channel by holding down the PTT switch (it must be released to make another attempt).

Occasionally, 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.

Talk-Around

Normally, all transmissions go through a repeater. Therefore, if you are out of radio range of the repeater, you cannot talk to anyone, even if you are only a short distance away from the mobile you are calling. To allow communication if this occurs, the talk-around feature can be used to enable direct mobile-to-mobile communication without going through a repeater.

Each selectable group can be programmed for talk-around. It is then automatically selected when the group is selected. There is no special talk-around indicator although the group alpha tag on the lower line of the display may be used to indicate this feature.

Talk-around can also be selected by the TALKARND menu param- eter (see page 32) or T/A option switch. When talk-around is selected by this switch, “TA ON” is flashed on the lower line of the display. Then when it is disabled, “TA OFF” is flashed. Changing the selected system or group, enabling scanning, or turning power off causes talk-around to revert to the default condition programmed for the selected group.

Conventional systems can be programmed so that talk-around cannot be selected. If an attempt is then made to enable talk-around with the switch, “NO TALK” is flashed on the lower line of the display.
