TIME-OUT TIMER (TOT)
It is sometimes necessary or desirable to restrict a single
transmission to a specific maximum time. This feature
can be useful when accessing repeaters to prevent
repeater time-outs, or when particularly trying to
conserve battery power. Activate TOT anytime you
wish to limit your transmit time.
1 Press [F] (1 s) to enter Menu A.
2 Select "TOT" {page 22}.

selection appears.

• The available selections are OFF, 3, 5, 10, 20, and
30 minutes.
• Default: OFF

returns to Receive. To resume transmitting, release and
then press [PTT] again.
INHIBITING TRANSMIT
The transmit function can be disabled to prevent
unauthorized individuals from transmitting, or to eliminate
the risk of yourself accidentally transmitting.
