6.4.1 TRANSMIT TIME - OUT TIMER ( TOT )
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 first be released, then wait 10 seconds and then pressed again. This
Time-Out-Timer (TOT) prevents a continuous transmission that would result
from an accidentally stuck PTT switch.
When the HX300 comes in contact with water a red light will blink to
assist retrieving it in low light conditions. The light will automatically
turn off in about 15 seconds when it is removed from water.
The HX300 has a menu selection to enable, disable and select differ-
ent blinking light times. Refer to Menu Mode Item "FL ( WATER EN-
ABLED LIGHT ) " on page 33 for details.
