Linear 1090 installation instructions Transmitter Battery Replacement, To Replace or ADD a SET

TRANSMITTER BATTERY REPLACEMENT

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.

TO REPLACE OR ADD A SET

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.

OPERATIONAL CHECK

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 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 maybe 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 or they may be returned, postage prepaid.

Installation Instructions

GARAGE DOOR RADIO CONTROLS

Model 3089 Transmitter

Model 1090 Receiver

WARNING:

∙Disconnect power before any installation or repair

∙Wear safety glasses

Your MULTI-CODE™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™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 spec ifying the M odel N um ber and the R F frequency designated on the identification label. No RF adjustments are needed nor should any be attempted.

RECEIVER INSTALLATION

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

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