Installation Instructions
SELECTING A CODE
If you have two single channel receivers: Set your
transmitter so that code switch #1 will match receiver #1. Set
code switch #2 on the transmitter to match receiver #2 (see
diagram #1).
If you have a MULTI-CODE 3021 or 3028 two channel
receiver: Set the receiver and both transmitter code switch
positions 1-9 to match. The tenth position on your transmitter
code switches are used for channel selection. Channel 1 on
the receiver is selected by moving the tenth position of code
switch #1 on the transmitter to the off (open) position. Channel
2 on the receiver is selected by moving the tenth position of
code switch #2 on the transmitter to the on (closed) position.
Once the codes have been set, check the operation and
reassemble the transmitter case.
MINI-TRANSMITTER INSTALLATION
This transmitter is completely self contained, including battery
and can be operated while held in hand or while mounted in
the car. It is supplied with “hook and loop” fabric for easy
mounting or it may be added to your keychain using the slot
provided.
TRANSMITTER BATTERY REPLACEMENT
Replacement battery -12 volt alkaline lighter battery (Eveready
A23 or equivalent).
The transmitter battery can be checked or changed by
removing the phillips head screw located on the back of the
case and carefully separating the case halves to expose the
circuit board and battery. Simply slide out the old battery and
slide in the new, remembering to observe the battery polarity
molded on the case in the bottom of the battery compartment.
Note that if the red LED on your transmitter fails to light you
most likely have a weak or dead battery and it should be
replaced (see diagram #1).
OPERATIONAL CHECK
To check operation, move back a reasonable distance (about
50 ft.) and press the transmitter button. Operation should be
reliable at this distance but environment and location of both
the transmitter and receiver will affect the range. If the
transmitter is stowed well out of sight, it may be necessary to
remove it from its mounting and hold near the windshield. Try
different locations and positions. If operation is still
unsatisfactory, the problem may be isolated by:
1) Checking the door operator. If the door will not open
when the wall button is pressed, the problem is likely
to be the operator. If the door will open by pressing the
wall button, but not when the radio control button is
pressed, the problem is probably in the radios.
2) Replacing the transmitter battery. If, after performing
the above operational checks, the controls still do not
function, they should be returned to your dealer for
repair or replacement.

DIGRAM #2
Before placing your transmitter into service, we urge you to set
your code in order not to interfere with neighboring systems and
to provide security for your own system. We strongly urge that
several coding schemes be avoided: ALL ON; ALL OFF; 2, 4, 6, 8,
10 ON; 1, 3, 5, 7, 9 ON. These positions are similar to our or other
manufacturer’s test positions, or are frequently used.
You will note that the model 3083 transmitter has two, ten
position code switches (Note: the switches are in the “on”
position when the switch is depressed toward the number,
see diagram #2). In order to simplify coding of your transmitter
as much as possible, observe the following:
