PRESS CARD TO REBOOT
The UHF transmission modulation is the way the TRX743 sends audio to the receiver. The modulation format is
set from this menu. Please note if the transmission format that is set here, and the format set on the receiver
do not match, the receiver will be unable to decode the audio from the transmitter. Also note that after any
change to the transmit format is made the TRX743 will need to be rebooted by pressing the card key before the
new format takes effect.

Power Roll Mode

POWER ROLL:
OFF
Power roll will allow the transmitter to stay in a lower transmit power setting to conserve battery power, then
when triggered the transmitter will increase the output power.

OFF - Power roll is disabled and the TRX743 will remain at the set power level.

DIVA TRIGGER - A command from a Zaxcom recorder will cause the TRX743 to go to full power.

RECORD TRIGGER - When the transmitter goes into record either manually or from an AUTO-LOAD trigger
the TRX743 will go to full power.
