INSTALLATION INSTRUCTIONS
MODEL 3083
TWO-CHANNEL MINI-TRANSMITTER
Congratulations! You have just purchased a Multi-Code Digital Transmitter, which we believe to be the finest product of its kind on the market. With a little care, this transmitter should provide you with many years of excellent service. Please take a moment to read the following instructions and you will find that setting your new transmitter will be quite an easy matter.
ACCESSING THE CODE SWITCH AND BATTERY COMPARTMENT
The model 3083 two-channel Mini-transmitter case is composed of 2 halves which are held together by a small Phillips head screw. Removing this screw will allow access to the code switches and the battery compartment (see Diagram #1, below).
SELECTING A CODE
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 the coding
of your transmitter as much as possible, observe the following:
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 codes 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 a 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. The operation should be reliable at this distance but the 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 the 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.
