)
While the PTT

switch is held down, transmission time is limited to 5
minutes. This prevents prolonged (unintentional) transmissions. About 10
seconds 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 rst be released. This Time-Out-Timer (TOT) pre-
vents a continuous 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.
