CODING

Before placing your transmitter into service, we urge you to set your codes, in order not to interfere with neighboring systems, and to provide security for your own system. You will note that the model 4120 transmitter has two, ten position code switches (see figure 1). 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.

If you have two single channel receivers: Set your transmitter so that the ten position switch on side A will match your receiver #1. Set the ten position switch on transmitter side B to your receiver #2 (see figure 2).

If you have a MULTI-CODE™ 3021 or 3028 two channel receiver: Set the receiver and transmitter (side A and B) code switch positions 1-9 to match. The 10th position on your transmitter code switches are used for channel selection.

Channel 1 on the receiver is selected by moving the 10th position of the transmitter side A to the off (open) position. Channel 2 is selected by moving the 10th position of the transmitter side B to the on (closed) position. Once the codes have been set, check the operation and replace the lower cover.

TRANSMITTER INSTALLATION

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.
