Setting Transmitter Operating Frequency
The Operating Frequency of the SM is displayed
either in MHz or as a two-digit hexadecimal num-
ber. Pressing the FREQ button toggles between
the two display modes. The frequency can be set
with the unit in Standby Mode or while powered up
for normal operation.
Note:You must first find a clear frequency
with the receiver, then set the transmitter to
match.
To change the Operating Frequency of the SM
Series transmitter:
1) Press the FREQ button to enter this screen.
Note: The default display is in MHz. Pressing the FREQ button again
displays the operating frequency as a two-digit hexadecimal number.
2) While holding the FREQ button, use the Up or Down arrow buttons to
move the operating frequency up or down in 100 kHz increments from the
current setting. Holding the Up or Down arrows will cause rapid scrolling
through the frequencies.

LCD Backlight Settings
The LCD backlight can be set to turn off after either 5 minutes or 30 seconds
or stay on continuously. Hold the UP arrow in while powering up the unit to
enter the setup screen. Press the AUDIO button repeatedly to step through
the setup items to reach the backlight settings screen. Use the UP or DOWN
arrow button to select the desired setting.
Adjusting Gain for Microphone and User
The -20 and -10 LEDs indicate the audio
signal level and limiter activity. Once set,
the transmitter’s audio level setting should
not be used to control the volume of your
sound system or recorder levels. This gain
adjustment matches the transmitter gain
with the microphone’s output level, the
user’s voice level and the microphone’s position.
The audio input level can be set with the unit in
Standby Mode or powered up for normal operation.
Note: If several different people will be using the transmitter and there
is not time to make the adjustment for each individual, adjust it for the
loudest voice.
1) Attach the microphone and turn on the transmitter.
2) Position the microphone in the location where it will be used in actual
operation.
3) Observe the audio level LEDs while speaking or singing into the micro-
phone at the same voice level that will be used during use. While holding
the AUDIO button, press the Up or Down arrow buttons until the both the
-20 and -10 LEDs glow green, with the -20 LED occasionally flickering
red (+0 dB to +10 dB range during peaks).
Note: Setting the audio level too high reduces the dynamic range of the
audio signal. Setting the audio level too low may cause hiss and noise
in the audio.
Locking or Unlocking the Control Panel
The Lock mode disables the buttons to prevent
accidental changes to the settings. After the setup
is complete, press and hold the UP and DOWN ar-
rows and observe the countdown timer on the LCD.
When the timer reaches zero, “Loc” is displayed
and the controls are locked.
Important: The only ways to unlock a locked
transmitter are to remove the battery or unlock it via the remote
control. The remote control function must be enable. The unit will
always power up in “unlocked” mode.

Battery Installation
We recommend using lithium or high-capacity
rechargeable batteries for longest life.
Note: Standard zinc-carbon batteries marked
“heavy-duty” or “long-lasting” are not adequate.
The battery status circuitry is designed for the volt-
age drop over the life of lithium batteries.
To install new batteries:
1) Turn the Battery Retaining Screw counter
clockwise and rotate the cover plate to open the compart-
ment.
2) Insert the new battery (or batteries) into the housing,
positive (+) terminal first.
Important: On dual-battery transmitters, BOTH batteries go positive
(+) terminal first.
3) Replace the Cover Plate and tighten the Retaining Screw.
Configuring for Remote Control Use
Some transmitter settings can be changed with the
Lectrosonics RM Remote Control. However, you
must first configure the SM Series transmitter to
accept commands from the RM:
1) Press and hold the Down Arrow Button then
power on the transmitter by pressing the
Audio and Freq buttons simultaneously.
2) The LCD will display the status, either “rc ON” or “rc OFF.” To change the
setting, press the Up or Down arrow button.
3)Power Off the transmitter by pressing the Audio and Freq buttons simul-
taneously. The RC setting will persist when you Power Up the transmit-
ter again.
Note: SM Series transmitters with firmware version 1.6 and later are
factory set to “rc ON” by default.
Configuring for Power Restore (SMV & SMQV ONLY)
When using external power source through a
battery eliminator, Power Restore will return your
transmitter to the settings it had before it was
powered off. This eliminates the need to power on
through the unit itself.
1) Press and hold the Down Arrow Button then
power on the transmitter by pressing the
Audio and Freq buttons simultaneously.
2) The LCD will display the status, either “rc ON” or “rc OFF.” Press “AU-
DIO” or “FREQ” key to scroll to the “PbAc 0” setting and use arrow keys
to turn to “PbAc 1” for on.
3)When power is restored the unit will turn on with previous settings.

Using the Silver Paste
Threads provide
electrical contact
Silver paste is applied to thumbscrew threads on
new units at the factory to improve the electrical
connection from the battery compartment through
the housing on any SM Series transmitter. This
applies to the standard battery door and the
battery eliminator.
The small enclosed vial con-
tains a tiny amount (25 mg) of
silver conductive paste. A small
speck of this paste will improve
the conductivity between the thumbscrew and the case.
With improved conductivity (lower resistance) more of the
battery voltage can get to the internal power supplies caus-
ing reduced current drain and longer battery life. Though the amount seems
very small, it is enough for years of use. It is, in fact, 25 times the amount that
we use on the thumbscrews at the factory.
To apply the silver paste, first completely remove the cover plate from the SM
housing by backing the thumbscrew completely out of the case. Use a clean,
soft cloth to clean the threads of the thumbscrew.
NOTE: Do NOT use alcohol or a liquid cleaner.
Simply hold the cloth around the threads and turn the thumbscrew. Move to
a new spot on the cloth and do it again. Do this until the cloth remains clean.
Now, clean the threads in the case by using a dry cotton swab (Q-tip) or
equivalent. Again, clean the case threads until a fresh cotton swab comes
away clean.
Open the vial, and transfer a pinhead speck of silver paste to the second
thread from the end of the thumbscrew. A easy way to pickup a speck of paste
is to partially unfold a paper clip and use the end of the wire to acquire a tiny
bit of paste. A toothpick will also work. An amount that covers the end of the
wire is sufficient.
It is not necessary to spread the paste more than a little bit on the thread as
the paste will spread itself every time the thumbscrew is screwed in and out of
the case during battery changes.
Do not apply the paste to any other surfaces. The cover plate itself can be
cleaned with a clean cloth by rubbing the
slightly raised rings on the plate where it
contacts the battery terminal. All you want to
do is to remove any oils or dirt on the rings.
Do not abrade these surfaces with a harsh
material such as a pencil eraser, emery pa-
per, etc., as this will remove the conductive
nickel plating and expose the underlying alu-
minum, which is a poor contact conductor.
Apply paste to second thread
from end of thumbscrew
