INSTALLATION INSTRUCTIONS
MODEL 4120 TWO CHANNEL TRANSMITTER
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.
ACCESSING THE CODE SWITCH
Insert a small coin into the slot located at the bottom end of the transmitter. Twist the coin and remove
the access cover to expose the code switches and battery compartment.
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.
