Menus and Settings
There are four locations for setup options and settings 
accessed with the control panel:
  •  UP Arrow Menu and Settings
  •  DOWN Arrow Menu and Settings
  •  AUDIO button settings
  •  FREQ button settings
UP Arrow Settings
With the unit turned off, hold the UP arrow button and 
simultaneously press the AUDIO and FREQ buttons. 
Each successive press of the AUDIO button will step 
through the setup screens.
 • Compatibility Mode
 • Input Type
 • RF Power Output
 • LCD Backlight
 • Frequency Step Size
Use the UP and DOWN arrow buttons to scroll through 
the options. The selected options will automatically be 
stored when the power is turned off. Press both the 
AUDIO and FREQ buttons to exit the menu and turn 
the power off. 
Then press the AUDIO and FREQ 
buttons at the same time
Hold the UP 
arrow button
Note: The unit is automatically set to “standby” in 
this setup mode; with rF OFF not displayed.
Compatibility Mode
These modes provide 
DSP-based emulations for 
use with earlier Lectrosonics 
equipment and with some 
models from other manufacturers.
  •  CP NU Hybr:  Nu Hybrid mode
  •  CP IFb:    IFB Series mode
  •  CP 3:    Mode 3 (contact the factory 
      for details)
NOTE: If your Lectrosonics receiver does not 
have Nu Hybrid mode, set the receiver to Euro 
Digital Hybrid Wireless® (EU Dig. Hybrid).
Input Type
The input can be configured for electret or dynamic 
microphones or a line level input.
The transmitter features unique Servo Bias input cir-
cuitry that automatically adjusts the current to maintain 
a selected bias voltage for electret microphone. This 
effectively overcomes a traditional problem with varia-
tions in output levels and power supply currents of 
different microphones.
Press the UP and DOWN arrows to select the desired 
input type:
 • LInE  Bias turned off; line level impedance
 • PH oFF  Bias turned off for dynamic mics
 • PH 2  Bias at 2 volts for electret mics
 • PH 4  Bias at 4 volts for electret mics
The correct bias is specified by the microphone manu-
facturer. 4 volts is typical for most electret lavaliere 
microphones. 2 volts is preferred by some mic manu-
facturers such as Countryman for the very small B6 
and E6 models.
RF Power Output
This setting provides an 
option for the trade-off 
between operating range 
and battery life. The lowest 
power setting provides maximum battery life, and the 
highest power setting provides maximum operating 
range and can also help to suppress some types of 
interference from broadband RF noise.
NOTE: See the specifications for typical 
operating times for each power level. (10 mW is 
the only option for E02.)
 • Pr 50  for maximum battery life
 • Pr 100  is an intermediate setting
 • Pr 250  for maximum operating range
LCD Backlight
The backlight on the display 
can be set to stay on all the 
time or to turn off after either 
30 seconds or 5 minutes of 
inactivity on the panel switches. The backlight will turn 
on and the timer will start over when a button is 
pressed. Use the UP and DOWN arrow buttons to 
select the desired setting.
 • bl 5  Stay on for five minutes
 • bl 30  Stay on for 30 seconds
 • bl on  Stay on continuously
