LEVEL
The LEVEL setup screen displays the audio output level
of the receiver in dBu. Use the SEL Up or Down buttons
to change the level. Range is from -50 to +5 dBu in 1 dB
steps.
TONE
The TONE setup screen enables an
audio test tone at the receiver output
for precise level matching with other
equipment. The first screen prompts you to press the SEL Up button to enable
the tone at the receiver output jack. The next screen that appears allows the
level to be adjusted in 1dB steps using the SEL Up and Down buttons.
TXBAT
The TXBAT setup screen allows you to select the exact
battery being used in the transmitter to provide more ac-
curate battery level monitoring. Use the SEL Up and Down
buttons to select the transmitter battery. Press MENU to leave this screen.
In native 400 Series hybrid mode as well as in the 200 Series compatibility
mode, the TXBAT menu offers six choices. (Monitor voltage with battery icon
in main window unless otherwise noted):
9V ALK - 9V alkaline battery.
9V LTH - 9V lithium battery.
9V TIM - 9V battery. Display its voltage normally in the battery level window
but monitor its status with the battery timer in the main window.
AA ALK - AA alkaline battery.
AA LTH - AA lithium battery.
AA TIM - AA battery. Display its voltage normally in the battery level window
but monitor its status with the battery timer in the main window.
The 9V TIM and AA TIM settings are most useful for LiPolymer and NiMH
rechargeable batteries as they do not exhibit reliably identifiable voltage drops
as they discharge.
In compatibility modes other than 400 Series and 200 Series, no battery
telemetry information is available so the TXBAT setup screen offers only two
choices:
NOTIMER - Display no transmitter battery status in the main window.
TIMER - Monitor the transmitter battery status with the battery timer in the
main window.
Note: To reset the battery timer, hold MENU and SEL Down together
for one second.
PHASE (Polarity)
The output PHASE setup screen allows the audio output
polarity to be inverted. The SEL Up and Down buttons
can be used to toggle between normal and inverted po-
larity. Press MENU to leave this screen.
