4. Multiple Transmitters
Each transmitter comes factory programmed with random codes.
1-channel transmitters have one random code, 2-channel transmitters have 2 different random codes, one per button, and 4channel transmitters have 4 different random codes, one per button. Transmitters that accompany a power head have at least
one code that already matches that power head. Transmitters
that are purchased separately as accessories have random codes
that must be changed in order to match the code of the “active”
transmitter you are already using. Below are instructions for
transferring an active code from a button on one transmitter to
a button of your choice on another transmitter.
■ Remove battery compartment covers (as shown previously in
Figure 1) of both transmitters, the one with the active code
and the new transmitter that needs to receive the active code.
■ Connect programming cable to both transmitters. Line up
either end of the stripped cable so 3 wires align with 3-hole
terminal, then firmly insert cable. See Figure 3.
■ Press and hold button on transmitter with the active code ((L)
in Figure 3). Midi and Mini transmitters have indicator lights
that will blink to show that code transfer is ready.
■ While keeping the transmitter (L) button pressed, press and
hold the button on the new transmitter (R) that you want to
transfer the active code to.
■ Code transfer will occur in approximately 2 seconds. If the
new transmitter (R) is a Midi or a Mini, the indicator light will
illuminate continuously to show that transfer is complete.
■ All buttons can be released. Code transfer is completed.
■ Cable can be removed and the covers replaced.
■ Both transmitters can now be used to operate the same door.
Note: For multi-button transmitters, be sure to carry out this
procedure for all the buttons you desire to use.
For micro transmitters, follow the same steps only there will
be no LED light indication.
