Menu Item Descriptions
LEVEL
This setup screen displays the audio output level of the 
receiver in dBu when the transmitter is fully modulated. 
Press the MENU/SEL button to toggle between receiver 
1 and receiver 2. Use the UP or DOWN buttons to 
change the level. Range is from -50 to +5 dBu in 1 dB 
steps. Press the BACK button to leave this screen.
The output levels at the two jacks may be set indepen-
dently, regardless of the diversity mode setting.
DEFAULT
Restores the factory default settings.
LOCALE (Band C2 units only)
The LOCALE setup screen has two settings, “--” and 
“JA”. If “JA” is selected, C2 band coverage stops at 
713.9 MHz. If “--” is selected, C2 band coverage goes 
all the way to 716.775 MHz.

IR SYNC
Navigate to this menu item to manually initiate the IR 
sync transfer. Hold the IR ports on the transmitter and 
receiver facing each other a foot or two apart and press 
the UP arrow for channel 1 or the DOWN arrow for 
channel 2. Watch for a confirmation on the transmitter 
LCD to verify the settings were correctly transferred. If 
one or both settings could not be enabled on the trans-
mitter, an error message will appear on its screen.
SCAN
See the section entitled Finding Clear Frequencies 
with Manual Scanning.
DIVMODE
The SWITCH diversity mode (dual channel mode) al-
lows the two internal receivers to operate independently 
on different frequencies and settings with two different 
transmitters. Diversity reception uses an antenna phase 
switching technique on each receiver. When this mode 
is selected, the setup screens will prompt you to select 
the receiver to be adjusted.
The RATIO mode combines the two internal receiv-
ers to pick up the same transmitter and mix their audio 
outputs in a ratio panning mode. In this mode, the setup 
screen for frequency will prompt you for a single value 
which will automatically be set for both receivers.
TALKBACK
This is a special function that re-directs the audio output 
of the transmitter in use to the channel 2 output when 
a button is pressed on the transmitter. The normal use 
is to provide a “com” channel so the person using the 
transmitter can have a direct line to the crew or produc-
tion staff that is not sent to the program output. The 
HHa hand held transmitter provides a programmable 
switch on the housing that can be configured for this 
function.

Programmable button
As long as the button 
is held in, the audio 
will appear at the 
channel 2 output. 
When the button is 
released, the audio 
output will switch 
back to channel 1.
To enable this mode, 
simply select Talk-
back in the menu and use the UP and DOWN arrow 
buttons to turn the function on. The mode must also be 
enabled on the transmitter.
Talkback works the same way in either the SWITCHED 
or RATIO diversity modes, but ONLY works in the HY-
BRID compatibility modes.
NOTE: When Talkback is enabled, only receiver 1 and 
a blinking TB will appear in the Main Window.
COMPAT
Compatibility modes adjust the FM deviation and audio 
processing (companding) to match other Lectrosonics 
models and some models from other manufacturers.
