Chapter Seven: General Operation
Timeout Timer
Tail messages are generated when users allow the repeater carrier
to drop (at the end of the hang time) so that they don't interrupt a
conversation in progress. They also will occur no more fre­
quently than defined by the Tail Message Timer to keep them
from becoming annoying. For example, if the Tail Message
Timer is set to five minutes, tail messages will not occ~
more
frequently than every five minutes.
There are two repeater timeout timers available to limit transmis­
sion duration in case of a continuous carrier at the repeater's
receiver. Both are programmable and control operator selectable
(only one can be seleCted at a time). The timer resets automati­
cally when the signal at the receiver has gone away for 650 ms.
Normally,a courtesy tone is generated at that time. However, if
an Anxious ID is waiting, the ID message will be generated in
place of the courtesy tone and will be followed by the tone. In
either case, the timeout timer resets at the beginning of the
courtesy tone orAnxious ID.
If users don't wait for the courtesy tone and the total transmis­
sion time between timer resets exceeds the programmable time­
out timer value, the controller will announce, "Repeater Time
Out", and the transmitter will be shut off. When the signal at the
input goes away for at least 650 ms, the transmitter will be re­
enabled and will announce "Repeater Time Out Cancel."

at the receiver.
