Multi-Code 3089 and 1090 Installation Instructions


  • Disconnect power before any installation or repair.
  • Wear safety glasses.

Your MULTI-CODE TM Radio Controls are designed specifically to remotely control a garage door from within an automobile and to give years of dependable service without adjustment. The transmitter/receiver combination utilizes the MULTI-CODE TM scheme which permits the selection of as many as 1024 code combinations of the owner’s personal choice. Because all radio controls are set with the even numbered switches in the “ON” position when they leave the factory, it is recommended that a different code be selected and set at the time of installation. Please refer to the “Accessing the Code Switch” section for instructions. The radio frequency (RF) portion of the controls, however, are tuned to standard frequencies and are thoroughly tested at the factory. This permits the addition or replacement of either the transmitter or the receiver by specifying the Model Number and the RF frequency designated on the identification label. No RF adjustments are needed nor should any be attempted.


The receiver is designed to mount directly into the operator. It can be remotely installed if the operator terminal strip is not accessible, or if the power for the receiver is not obtainable from the operator. To direct mount the receiver, simply loosen the terminal screws on the operators and insert the two-way lugs from the receiver under the screw heads along with the wall bottom wires and tighten the screws. See Figure #1.

Figure 1

Place the antenna (an 11 inch white wire) in a vertical position as far from any metal as possible.

For remote installation the receiver may be mounted near the operator head on a joist or the ceiling by using the mounting tab. Order Model 1092-06 adapter, which permits connection between the operator terminal and the two-way lugs on the receiver

Figure 2

Slip on connectors at one end of the adapter, connect to the flat side of each spade lug on the receiver, and connect the spade connectors at the other end to the operator terminal. Connect the wires as follows:
(a) White wire to terminal “1” or “24V”
(b) Black wire to terminal “2” or “Relay”
(c) Red wire to terminal “3” or “Common” (“Radio Power”)
(d) Connect push button wires to terminal “1” and “2” (See Figure #2)

Where power for the radio receiver is not available from the operator, order a Model 1092-01 power transformer adaptor for connection between the operator and the remote receiver.


Using a small screwdriver, pry the rectangular hatch from the receiver for access to the code switch. On the transmitter the entire front lower half of the case is removable. Grasp the front lower half of the case  near the bottom on both sides and pull upward away from the transmitter; this will disengage the lower end. Then pull downward to remove the lower cover and expose both the code switch and the battery compartment. Set both switches to the code of your choice, being sure both are set the same since a different setting of just one switch will prevent operation. The digital code is determined by the position of 10 small switches numbered 1 through 10 located in the receiver and transmitter. Any combination of “on” or “off” positions can be selected by using a pencil or ball point pen. (Note: The switches are in the “on” position when the switch is depressed toward the number). Se Figure #3.

Figure 3

Once the codes have been set, check operation and reinsert the hatches.


The transmitter is completely self-contained, including battery, and can be operated while mounted in the car. It is supplied with a clip for attaching to the sun visor, if desired, If the clip is used, attach to the case by sliding it into the recess provided on the back of the transmitter until the small dimples fit into the holes in the clip.

CAUTION: Keep the clip flat when pushing it into position so that it doesn’t extend down into the case where it could touch the circuit board and cause damage.


Replacement battery: 9 Volt NEDA 1604 (Eveready 216 or equivalent).
The battery in the transmitter can be checked or changed by removing the front lower half of the transmitter. Refer to the directions under “accessing the code switch” for battery replacement.


A replacement or new transmitter or receiver may be purchased by specifying the Model Number and the RF frequency designated on the identification label. The RF frequency is set at the factory and must not be adjusted in the field. The digital code can be matched to the companion receiver or transmitter by following the above procedure.


To check operation move back a reasonable distance (about 50 feet) and press the transmitter button. Operation should be reliable at this distance, but environment and location of both the transmitter and the receiver will affect the range. If the transmitter is stowed well out of signt, it may be necessary to remove it from its mounting and hold it near the windshield. Try different locations and positions. If operation is sstill 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.

CAUTION: Any changes or modifications in intentional or unintentional radiators which are not expressly approved by STANLEY ELECTRONICS could void the user’s authority to operate this equipment. This applies to intentional and unintentional radiators certified per part 15 of the F.C.C. rules and regulations.
