Operation Manual

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.

dicating such a transmission is not permitted.
