INSTALLATION INSTRUCTIONS
MODEL 4140 FOUR 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 4140 transmitter
has two 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.
