CONVENTIONAL FEATURES

when the PTT switch is released after the transmitter has been disabled. If the PTT switch is pressed during the penalty time, the time-out indication occurs again. A beep sounds when the penalty timer expires and the transmitter can then be keyed.

Conversation Timer

A conversation timer can be programmed on conventional channels to limit the total length of a conversation rather than just the length of each transmission as with the time-out timer. This timer is reset when the time between transmissions exceeds the penalty time just described. A warning tone sounds 5 seconds before the conversation timer expires. When it expires, the transmitter is disabled and a warning tone sounds. The transmitter remains disabled for the length of the penalty time, and a beep sounds when it can be keyed again.

Repeater Talk-Around

Normally, all your transmissions go through a repeater which usually increases range. However, if you are out of range of the repeater, you cannot talk to anyone else on that channel even though the mobile you are calling may be only a short distance away. To allow communica- tion when this situation occurs, repeater talk-around can be used to allow direct communication with a mobile without going through a repeater.

Repeater talk-around can be selected if the Repeater Talk-Around option switch is programmed. When talk-around is enabled by this switch, the icon is displayed and “RTA ON” is flashed in the display. Then when it is disabled by pressing the switch again, that icon is no longer displayed and “RTA OFF” is flashed. Changing channels or turning power off does not change the selected talk-around mode.

Power Output Select

If the High/Low Power option switch is programmed and power selection is permitted on the current channel, either high or low trans- mitter power can be selected. Generally, the high power setting allows you to transmit longer distances but uses more battery power, and the
