TRANSMIT MENU
UHF Transmitter Power Level Set
The UHF transmit power of the TRXLA3 is set from this page. The transmit power can be adjusted to
output 25, 50 or 100mW. The higher the power setting the more battery power will be required.
UHF Transmit Modulation Set
The UHF transmission modulation is the way the TRXLA3 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 the TRXLA3 will need to be rebooted by pressing the card key before the new
format takes effect.

Power Roll Mode
Power roll will allow the transmitter to stay in a lower transmit power setting to conserve battery power, and
then when triggered the transmitter will increase the output power.

OFF - Power roll is disabled and the TRXLA3 will remain at the set power level.

DIVA TRIGGER - A command from a Zaxcom recorder will cause the TRXLA3 to go to full power.

RECORD TRIGGER - When the transmitter goes into record either manually or from an AUTO-LOAD trigger
the TRXLA3 will go to full power.
