OPERATION OF YOUR OPENER

devices:
• Opener Control Panel: UP & DOWN buttons, and
O.S.C. control button.
• Transmitter: hold the button down until the door
starts to move.
• Wireless Entry Keypad: This is an accessory that
opens the door using a four digit keycode.
When the opener is activated:
• If open, the door will close. If closed, the door will
open.
• If closing, the door will stop.
• If opening, the door will stop (allowing space for
entry and exit of pets and for ventilation).
• If the door has been stopped in a partially open or
closed position, it will reverse direction.
Obstruction behaviour:
• If an obstruction is encountered while closing, the
door will reverse to the fully open position.
• If an obstruction is encountered while opening, the
door will stop and briefly reverse.

prevents an open door from closing. It is
STRONGLY RECOMMENDED for homeowners
with young children or pets.
