Model 4120 Two
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 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.
THE CODE SWITCH
On the model 4120
transmitter the entire front lower half of the case is removable by inserting a
small coin in the slot provided with a twisting motion. Once opened you will
have access to both code switches and the battery compartment.
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. 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 to 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.
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 to 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.
The transmitter is
completely self contained, including battery, and can be opened 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 fir into the holes in the
ALL MULTI-CODE door related
