6.3.1 TRANSMIT TIME - OUT TIMER
(
TOT
)
While the PTT
( )
switch is held down, transmission time is limited to 5 min-
utes. This prevents prolonged (unintentional) transmissions. About 10 sec-
onds before automatic transmitter shutdown, a warning beep will sound from
the speaker. The transceiver automatically switches to the receiving mode,
even if the PTT
( )
switch is held down. Before transmitting again, the PTT
( )
switch must first be released. This Time-Out-Timer (TOT) prevents a con-
tinuous transmission that would result from an accidentally stuck PTT
( )
switch.
NOTE
The PTT
( )
switch is disabled for 10 seconds after the transceiver
automatically switches to the receiving mode by the TOT feature.
