WARNING
Install the control station and receiver where the door is
visible, but away from the door and its hardware. When a
receiver is used to activate a commercial door opener, a
reversing edge MUST be installed on the bottom of the door.
Failure to install a reversing edge under these circumstances
may result in SERIOUS INJURY or DEATH to persons trapped
beneath the door.
To use the remote control with a
3-channel receiver and 3-button door
control to operate a commercial door
