SETUP Window
In the SETUP window, the SEL Up 
and Down buttons scroll through a 
list of eight possible setup screens: 
EXIT, LEVEL, TONE, TXBAT, PHASE, SmtNR (in 400 
Series mode only), TUNING and COMPAT. Each of 
these setup screens allows the user to change the as-
sociated operating parameters. Pressing the MENU 
button accesses whatever mode is identified in the 
Setup window. Pressing the MENU button whenever 
EXIT is displayed returns the user to the Main window.
LEVEL Setup Screen
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. Press the MENU but-
ton to leave this screen.
TONE Setup Screen
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.
When the audio test tone is enabled, the received audio 
is muted and an internally generated 1 kHz test tone is 
routed to the XLR connector. Since there is only one 
audio output level setting for both the received audio 
and test tone, the level set here will be retained in the 
receive mode (it will supersede the setting made in the 
LEVEL setup screen.) The test tone has 1% distortion 
and is intended for confirmation of output levels only. 
To exit the test tone screen and stop the tone press the 
MENU button.
TXBAT Setup Screen
The TXBAT setup screen allows you 
to select the exact battery being used 
in the transmitter to provide more 
accurate battery level monitoring. Four different types 
of batteries are commonly used in Lectrosonics trans-
mitters: 9 Volt alkaline, 9 Volt lithium, AA alkaline, and 
AA lithium. Correctly set, this will ensure that adequate 
warning will be provided in advance of battery failure. 
Use the SEL Up and Down buttons to select the trans-
mitter battery. Press MENU to leave this screen.
In native 400 Series mode as well as in the 200 Series 
compatibility mode, the TXBAT menu offers six choices:
9V ALK   Transmitter uses a 9V alkaline battery. 
Monitor voltage with battery icon in main 
window.
9V LTH  Transmitter uses a 9V lithium battery. Moni-
tor voltage with battery icon in main window.
9V TIM   Transmitter uses a 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  Transmitter uses a AA alkaline battery. 
Monitor voltage with battery icon in main 
window.
AA LTH  Transmitter uses a AA lithium battery. Moni-
tor voltage with battery icon in main window.
AA TIM   Transmitter uses an 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 
NiMH 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 Setup Screen
The PHASE setup screen allows the 
audio output phase to be inverted. 
The SEL Up and Down buttons can 
be used to toggle between normal and inverted phase. 
Press MENU to leave this screen.
SmartNR Setup Screen
The SmartNR setup screen (available 
in 400 Series compatibility mode only) 
places the Smart Noise Reduction 
algorithm in one of three modes. In 
the OFF position, no noise reduction 
is applied, for complete transparency. 
In the NORMAL position (factory 
default setting), a moderate amount 
of noise reduction is applied, dramati-
cally reducing hiss with virtually no 
discernible side effects. In the FULL 
position, the transparency is superior to the Lectroson-
ics noise reduction system used for many years in the 
195 and 200 series systems. Try switching between the 
three modes to decide what setting is correct for your 
application. Refer to the Smart Noise Reduction section 
in the General Technical Description chapter for more 
detailed information about this feature.
