Associated model number: 3089

Congratulations! You have just purchased a MULTI-CODE Digital Transmitter, which we believe to be the finest product of it’s 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.


On the model 3098 the entire front lower half of the transmitter 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, this will expose both the code switch and the battery compartment.


You may set your transmitter to any code you desire but be sure that the code you set matches the code has been set on your radio receiver. The digital code is determined by the positions of the 10 small switches numbered 1 through 10 located in the receiver and transmitter. Any combination of ON (CLOSED) or OFF (OPEN) positions can be selected by using a small screwdriver or ball point pen. (NOTE: The switches are in the “On” position when the side next to the number is pressed in.) In setting your personal code 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. Once the code has been set, check the operation and replace 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.


Replacement battery –9 volt NEDA1604 (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.
