The transmitter operates from a 3.7 V rechargeable battery that will provide
about six hours of operation per charge. Battery life can be monitored from
current Lectrosonics receivers.
The factory supplied battery charger provides a folding NEMA 2-prong plug,
and will operate from 100-240 VAC sources. The LED glows red during charg-
ing and turns green when the battery is fully charged.
CAUTION: Use only the factory supplied battery and battery
charger.

while powering the unit on. Press the AUDIO button repeatedly to scroll
through the menu items and use the UP and DOWN arrows to select the
values and settings for each item.
NOTE: Some Lectrosonics receivers include an IR (infrared) port
to transfer settings from the receiver to the transmitter. Refer to the
section on IR (infrared) Sync for details.
DOWN Button Menu
Hold the DOWN button while powering up the unit. Then press the AUDIO
button repeatedly to scroll through the following settings. Use the UP and
DOWN arrows to select the available options under each setting.

• PbAc (power-back-on after power loss); selections: 0 (stay turned off),
1 (turn back on)
• bL (back light duration); selections: 5 (minutes), 30 (seconds),
on (always on)

• In (Input configuration); press the UP and DOWN arrows to select one of
the following:
In dYn no bias, 0 (300 ohm); for dynamic microphones
In CoS 4v bias, 0 (300 ohm); phase reversed; for Sanken COS11,
Lectrosonics M152 and similar mics
In b6 2v bias, 0 (300 ohm); for Countryman B6 and similar mics
In dPA 4v bias, Lo (4k ohms); use for DPA lavaliere and similar mics
In L In no bias, HI (100k ohms); use for line level input
In otH 4v bias, 0 (300 ohms); same as CoS but audio phase is not
reversed; for various mics
In SEt Press the AUDIO button for manual setup to select the
following parameters, then use the UP and DOWN
arrows for each item to set the values.
bIAS bias voltage on the input; selections 0, 2 or 4

Set up Frequency and Gain
1)Use the receiver to find a clear frequency and set the transmitter to match.
2)Attach the microphone or signal source and adjust the input gain following
the steps on the next page.
3) Walk test the system through the area where it will be used to make sure
there are no dropouts.
Adjust the Input Gain
The two bicolor Modulation LEDs on the control panel provide a visual indica-
tion of the audio signal level entering the transmitter. The LEDs will glow either
red or green to indicate modulation levels as shown in the following table.
Signal Level -20 LED -10 LED
Less than -20 dB Off Off
-20 dB to -10 dB Green Off
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 dB Red Red
NOTE: Full modulation is achieved at 0 dB, when the “-20” LED first
turns red. The limiter can cleanly handle peaks up to 30 dB above this
point.
It is best to go through the following procedure with the transmitter in the
standby mode so that no audio will enter the sound system or recorder during
adjustment.
1)With a charged battery in the transmitter, power the unit on in the standby
mode (see previous section Powering On in Standby Mode).
2)Prepare the signal source. Position a microphone the way it will be used in
actual operation and have the user speak or sing at the loudest level that
occur during use, or set the output level of the instrument or audio device to
the maximum level that will be used.
3)Press and hold the AUDIO button with Aud and a numeral on the display
(e.g. Aud 22).
4)Use the and arrow buttons to adjust the gain until the –10 dB glows
green and the –20 dB LED starts to flicker red during the loudest peaks in
the audio.
5)Once the audio gain has been set, the signal can be sent through the
sound system for overall level adjustments, monitor settings, etc.
6)If the audio output level of the receiver is too high or low, use only the con-
trols on the receiver to make adjustments. Unless the microphone or its po-
sition changes, or a different instrument is being used, leave the transmitter
gain adjustment set according to these instructions. Use the audio output
level control on the receiver to make adjustments for the desired level being
delivered to the connected mixer, recorder, etc.

IR (infrared) Sync
An IR (infrared) link between an associated receiver and the transmitter can
be used to shorten setup time and ensure that the correct settings in the
transmitter are made. The dome on the side panel of the transmitter is the port
used for the IR link. The receiver is normally used to identify a clear operating
frequency. Once step size, frequency and compatibility mode are set in the
receiver, the settings can be sent to the transmitter via this IR link.
IR port
Place the transmitter close to the IR enabled receiver with the ports facing
each other within a foot or two apart. Send the settings with the trigger on the
receiver. If the settings are successfully transferred, a confirmation message
will appear on the transmitter LCD.
NOTE: If a mismatch exists between the receiver and transmitter, an
error message will appear on the transmitter LCD stating what the
problem is.
Removable Belt Clip
The belt clip may be removed by sliding it off the retaining tabs on the battery
door. Tilt the clip at angle to remove it.
When mounting the belt clip onto the battery door, carefully align the open-
ings with the retaining tabs on the door and press it into place. If the holes
and tabs are not precisely aligned, the door may not close and latch properly.
Align the openings
and tabs precisely.
