Operation Of Your Opener

Your opener can be activated by any of the following devices:
• The Remote Control Transmitter. Hold the push button down until the door starts to move.
• The Backlit Door Control Button (if you have installed this accessory). Hold the button down until door starts to move.
• The Outside Keylock or Keyless Entry System (if you have installed either of these accessories).
Opening the Door Manually:
Door should be fully closed if possible. Weak or broken springs could allow an open door to fall rapidly. Property
damage or serious personal injury could result.
The door can be opened manually by pulling the release handle down. To reconnect the door, activate the unit.
Do not use the manual release handle to pull the door open
or closed.
When the Opener is Activated by Remote Control or Door Control Button:
1. If fully open, the door will close.
2. If closed, the door will open.
3. If opening or closing, the door will stop.
4. If partially open, the door will move in the opposite direction of last travel.
5. If an obstruction is encountered while closing, the door will reverse to the open position.
6. If an obstruction is encountered while opening, the door will reverse for 1 second.
7. The optional Protector System™ uses an invisible beam which, when broken by an obstruction, causes a closing
door to open and prevents an open door from closing. It is STRONGLY RECOMMENDED for homeowners with
young children.
Allow a 15 minute cooling period after 5 continuous operations of the opener.
The opener light will turn on: 1. when opener is initially plugged in;
2. when the power is interrupted; 3. when the opener is activated.
The light turns off automatically after 2-1/2 minutes. Bulb size is
21 Watts maximum.
