MULTI-CODE
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
On the model 4140 the entire
front lower half of the transmitter 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.
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. 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.
TO SET YOUR
TRANSMITTER AND RECEIVERS:
Receiver 1
– Set the receiver code switch positions 1-8 to match transmitter side A code
switch positions 1-8. Set the 9th position on the receiver and the
transmitter to the on (closed) position. Set the 10th position on the
receiver and the transmitter to the off (open) position
Receiver 2 –
As you
did in the procedure for Receiver 1, Set your receiver code switch positions 1-9
to match transmitter side A code switch positions 1-9. Set 10th
position on the receiver to the on (closed) position (Note: The 10th
position switch on the transmitter side A has previously been set to the off
(open) position in the above step).
Receiver 3 -
Set the
receiver code switch positions 1-8 to match transmitter side B code switch
positions 1-8. Set the 9th & 10th positions on the
receiver and the transmitter side to B to the off (open ) position.
RECEIVER 4 -
As you
did in the procedure for Receiver 3, set your receiver code switch positions 1-9
to match transmitter side B code switch 1-9. Set the 10th position on
the receiver to the on (closed) position (Note: the 10th position
switch on the transmitter side B has previously been set to the off (open)
position in the above step).
If you are using
Two-Multi-Code 3021 or 3028 two channel receivers:
Receiver channel 1

the receiver code switch Positions 1-8 to match transmitter side A code switch
positions 1-8. Set the 9th position on the receiver and transmitter

will now match Channel 1 on your #1 two channel receiver (see figure 2 for
side A and B transmitter code switch locations).

receiver and transmitter side A code switch positions have previously been set
in the above step. Pushbutton 2 on your transmitter will match Channel 2 on your

positions 1-8. Set the 9th position on the receiver and transmitter
