Manual
PRODUCT DESCRIPTION
The Model LMT-1 is a compact light-weight, wireless transmitter. When activated
by pressing the button for two seconds, it will trigger the remote receiver
programmed to recognize the transmitter.
Measuring only 1.5 by .75 inches, the LMT-1 can be worn on the supplied lanyard
or attached to a keyring. The transmitter is supplied with an adjustable lanyard
with a breakaway release.
The LMT-1 incorporates Linear’s proprietary “MegaCode” circuit that provides
each transmitter with over one million security codes.
A Duracell MN21 battery powers the transmitter. The red LED on the front of the
transmitter will light when the unit is activated.
TRANSMITTER CODING
Each LMT-1 transmitter has been pre-programmed at the factory to one in a
million codes. The transmitter will retain its pre-programmed code even with low
or no batteries. Refer to the receiver’s instructions for details on programming the
transmitter into the receiver. Most receivers have a “learning” or “program” mode.
Triggering the transmitter with the receiver in a “learning” mode will cause the
transmitter’s code to be entered into the receiver’s memory.
FEATURES
OPERATING THE UNIT
To send a signal to the receiver, a single button on the face of the transmitter must
be pressed for a minimum of two seconds. When the unit is sending a signal, the
red LED will light.
TRANSMITTING RANGE
The maximum transmitting range is determined by the receiver used, and various
conditions in the installation.
BATTERY LIFE & LOW BATTERY INDICATION
Under normal conditions, the 12 volt Duracell MN21 battery should last 12 to 18
months. When the battery gets low, the red LED will fl icker dimly when the unit
is activated
CHANGING BATTERIES
STEP 1: Twist the lanyard loops
and remove the battery door. (see
fi gure 1)
STEP 2: Carefully remove the old
battery and discard according to
manufacturers recommendations.
Step 3: Install a fresh battery as
shown in Figure 2. Replace the
transmitter battery door.
TESTING
When the transmitter button is pressed, the red LED should light indicating that
the unit is transmitting and the battery is good. If the LED does not light, the
battery is low, dead or installed incorrectly.
Operate the transmitter from various locations to identify any weak signal areas or
“dead spots” that may be caused by interference or certain metal obstacles.
IMPORTANT: The transmitter button must be pressed for a minimum of two
seconds to activate the receiver.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fi ll an important need in portable wireless
signaling. However, there are some limitations which must be observed.
✴ For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as
Part 15 devices. As such, they have limited transmitter power and therefore limited range.
✴ A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio
signals that occur on or near their operating frequencies, regardless of code settings.
✴ Changes or modifi cations to the device may void FCC compliance.
✴ Infrequently used radio links should be tested regularly to protect against undetected interference or
fault.
✴ A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale
distributor or dealer, and these facts should be communicated to the ultimate users.
This device complies with FCC Part 15 and Canada Rules and Regulations. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference and (2) this device must
accept any interference received, including interference that may cause undesired operation.
