Selecting Compatibility Mode
This transmitter is capable of working with Lectrosonics
400 Series Digital Hybrid Wireless™, 200 Series, 100
Series, and some analog wireless receivers from other
manufacturers. (Contact Lectrosonics for details.) The
transmitter must be set for compatibility with the match-
ing receiver, which is easily done using the supplied
screwdriver and a battery.
Note: The unit is supplied from the factory
configured as a 400 Series transmitter.
1) Set the audio output controls for the corresponding
receiver to minimum.
2) Install a good bat-
tery in the trans-
mitter. Turn on the
transmitter and
observe the Power
LED to determine
the current Com-
patibility Mode.

blink:

3) With a small screwdriver (included with your unit),
set the Frequency Switches to “CC” (for Change,
Change).
IMPORTANT: When performing the following
steps, The transmitter allows ten seconds to
set the frequency switches before the next
toggle of the power switch. When toggling the
power switch, it is not neccesary to allow the
transmitter to turn off completely. If more than
ten seconds elapse between toggles, the mode
change will not take effect and you must begin
again from step 3.

Adjusting the Audio Gain
1) Install a good battery in the transmitter. Move the
Power Switch to On and observe the Power LED. It
should blink the compatibility mode, then glow green.
2) Set the Attenuator control to “F” before adjusting the
input gain.
3) Hold the microphone the way it will be used in ac-
tual operation.

that will actually be used during the program. Adjust
the Audio Level control while observing the Modula-
tion LEDs until the –20 dB LED occasionally flickers
red and the -10 dB glows green.

Note: If the Audio Level control is at minimum
and both Modulation LEDs still blink red
frequently, then additional attenuation is needed.
Unscrew the windscreen and carefully lift it off
the top of the unit. Rotate the Attenuator control
counterclockwise from “F” one step at a time until
the Modulation LEDs indicate at the desired level.
5) Once the audio gain has been set, the signal
can be sent through the sound system for
overall level adjustments, monitor settings, etc.
