PROGRAMMING THE
TRANSMITTER
Make sure that no people or
objects are in the path of the
garage door or other device you
are programming.
If you are programming a garage
door, it is recommended that you
park the vehicle outside the
garage.
For quicker and more accurate
transmission of the radio frequen-
cy, install a new battery in your
hand-held transmitter.
Determining the Code Type
Some older garage door openers
are fixed code transmitters.
The same signal is sent each time
the button is pressed.
If the device operates with a fixed
code, there will be a series of
switches present when you
remove the battery compartment
cover.
An example of the switches is
shown above.
The motor head unit for a garage
door opener may also have a set of
switches.
