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.

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.

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.

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
