PTT
has been held continuously for 5 minutes, transmission is discontinued, the
message TX TIMEOUT appears, and the radio automatically returns to receive
mode.
After the timeout, the alarm continues to sound until
PTT
is released. The TX time
out timer is reset once the
PTT
key is released.
Note:
If the current channel is receive-only, an alert tone sounds when PTT is pressed, in-
dicating such a transmission is not permitted.
