NOTE: If the transmitter fails to activate
the receiver, first check the coding
switches in the receiver to make sure that
the receiver’s digital code system
matches that of the miniTransmitter. Next
check the battery and replace it if it is
weak. Although the battery should last for
two years with normal use, it is good
practice to install a new battery every
year. A slowly flashing or steadily lit LED
on the transmitter indicates that the
battery is too low for transmission to
occur. A rapidly flickering light during
transmission indicates that the unit is
operating properly.

IMPORTANT !!!
Linear radio controls provide a reliable communications link and fill
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 a s Part 1 5 device s. 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 modifications to the device may void FCC compli-
*
ance.
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 wholesa le distri butor or dealer , and these
facts should be communicated to the ul ti mate use rs.

DESCRIPTION
The miniTransmitter is one of the smallest
portable signaling units manufactured by
Linear. This wireless transmitter owes its
miniature size to state-of-the-art circuit
technology. Only 5/8 inches thick, the
miniTransmitter measures 1-3/8 inches
wide by 1-7/8 inches high. It is compatible
with all Linear standard digital receivers.
CHOOSING A CODE
To code the miniTransmitter with the
receiver it operates, set the eight-digit
system code to the precise digital system
code set in the receiver. Do not retain the
original factory-set code.

In addition, among the 256 valid codes
available, four should not be used
because they are too often duplicated.
These codes are (1) all ON; (2) all OFF;
(3) alternating ON/OFF; (4) alternating
OFF/ON.
CODE SWITCH LOCATION
Remove the battery cover and battery
(see Figure 1), to access the
miniTransmitter’s toggle coding switch
(see Figure 2).

CODE SETTING
The coding is performed simply by using
a paper clip or similarly pointed object
(not a pencil or pen) to flip the eight
switches to On or OFF position. A toggle
switch set to the system code 1, 4, 7 ON
appears in Figure 2.
Reinstall battery observing polarity.
Replace battery cover.
CHECK-OUT AND TEST
After matching the digital code set in the
transmitter to the receiver code, test the
system.
CAUTION: Be sure the door or gate is
in sight and the area is clear prior to
testing.
To test the transmitter, perform the
following steps.
Step 1: Move at least 6 feet away from
the receiver and push the miniTransmitter
button. Receiver activation indicates that
the transmitter is operating properly and
that the transmitter/ receiver’s digital codes
are correctly matched.
NOTE: The miniTransmitter transmits
continuously while the button is held
down, terminating when the button is
released.
Step 2: Operate the transmitter from
various locations within the area where it
will be used. This will help to locate
possible null areas where structural steel,
and/or certain appliances may interfere
with transmission.
