transmitter have been factory-set to a matching
code which changes with each use, randomly
accessing over 100 billion new codes. Your opener
will operate with up to 64 merlin

purchase a new transmitter, or if you wish to
deactivate any transmitter, follow the instructions in
the Programming section.
Activate your opener with any of the following:
• The hand-held transmitter: Hold top middle button
down until the door starts to move.
• The wireless wall button CM128 press and hold the
large round button down until the door starts to
move.
• The Keyless Entry (See Accessories): Must be
programmed before use. See Programming.
• Multi-Function Door Control
When the opener is activated (with the safety reversing
sensor correctly installed and aligned)
1. If open, the door will close. If closed, it will
open.
2. If closing, the door will reverse.
3. If opening, the door will stop.
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will stop
and reverse. The LED indicator light will flash.
6. If obstructed while opening, the door will stop.
7. If fully open, the door will not close when the
beam is broken. The sensor has no effect in the
opening cycle.
If the sensor is not installed, or is misaligned, the
door won't close from a hand-held transmitter or
wireless wall button. However, you can close the
door with the multi-function door control, the
Outside Keylock, or Keyless Entry, if you activate them
until down travel is complete. If you release them too
soon, the door will reverse.
