Notes:
•
The Barrett PRC-4090 has a transmit time-out facility. This facility (when pro-
grammed) allows the transmitter to be keyed in transmit mode with the PTT
(transmit) switch for a set time period, after which the transceiver switches to
receive until the PTT (transmit button) is released and re-keyed. This facility
prevents the transmitter transmitting for long periods of time if, for example,
the microphone becomes jammed between seats in a vehicle causing the PTT
(transmit) switch to be held down. Enabling, disabling and changing the time
of the transmit timeout facility can be set either when programming the trans-
ceiver or in the RF Section of the Settings menu. See page 94.
•
The microphone up / down buttons can be congured for channel change or
volume control functions either when programming the transceiver or in the
General Section of the Settings menu. See page 62.
