LF ROLLOFF adjusts the low frequency 
roll-off point of each transmitter to suppress 
subsonic noise or to suit individual prefer-
ences.
TX PHASE selects the polarity (phase) of 
the audio signal in each transmitter. 
PROG SWITCH defines the function of a 
programmable switch present on some 
Lectrosonics transmitter models. The 
switch function can be configured as audio 
mute, power on/off, talkback or no function.
AUTO ON enables the transmitter to turn 
back on automatically when a battery is 
replaced, eliminating the need to manually 
turn it back on. The function can be en-
abled or disabled.
TX PANEL LOCK locks out the membrane 
switch panel to prevent inadvertent chang-
es being made. In the locked mode, the 
programmable switch (if available) is still 
operational, so it can still be used to turn power off and 
on. To unlock the panel, navigate to the Locked item in 
the menu and select No.
BATT TIMER is a function in the receiver 
that monitors the accumulated operating 
time of each transmitter. Rechargeable 
batteries maintain almost a constant 
voltage across the discharge cycle, so monitoring the 
voltage drop provides only very short notice near the 
end of life before the battery stops working. The best 
way to monitor rechargeable batteries is to run a test 
to determine how long it will run the transmitter, then 
use the timer to assess the remaining time.
TX BACKLIGHT sets how long the back-
light on the transmitter LCD will stay turned 
on. The options may vary between different 
transmitter models.
STEP SIZE sets the increments for fre-
quency adjustment at 100 or 25 kHz.
NARROW BAND is used to restrict the 
scanning and tuning adjustments on the 
receiver to a single block when used with a 
single block transmitter.
