Chapter 4: Operations
4.10 Transmitting
Press and hold the Press-to-talk (PTT) key to transmit on the selected
channel, then release to receive. The TX indicator appears during
transmission.
The radio is equipped with a timeout timer in the event of a stuck key. After
PTT has been held continuously for 5 minutes, transmission is discontinued
and the radio automatically returns to receive mode. An Error beep is emitted
10 seconds before the time out is triggered and TX flashes on the display until
PTT is released.
The TX time out timer is reset once the PTT key is released.
Note: If the current channel is a TX-prohibited channel, an alarm sounds
when PTT is pressed, indicating such a transmission is not permitted.
