WARNING!
Activate opener only when door/gate is in full view, free of obstruction and properly adjusted. No one should enter or leave
while door/gate is in motion. Do not allow children to operate or play with push buttons or remote controls. Do not allow
children to play near the door/gate.
NOTE: Only the original remote controls from the manufacturer should be used. Remote controls that may look very
similar, but do not originate from the manufacturer are not compatible. Such third-party remotes create malfunctions such
as automatic opening, and the guarantee on the function and safety expires.

Installation

1. Choose a mounting location suitable for your application such as a wall, flat surface, or a pedestal with 76mm x 76mm
mounting pattern, located equal or less than 2 m of installation height. Locate the keypad at least 1.8m away from any
moving part of the gate and where the user cannot reach over, under, around or through the gate to operate the controls.
The mounting location needs to be in line of sight of the moving gate.
2. Unlock and remove the faceplate from the mounting plate.
3. Mount the mounting plate to the desired surface and secure with screws or bolts.
4. Remove the battery cover using a screw driver. Connect the white battery connector to the PCBA (see illustration) and
reinstall the cover.
5. Reattach the faceplate to the mounting plate and lock with the key.
6. The garage door / gate opener must be programmed to accept the new keypad code. See basic programming.
