OPERATION OF YOUR OPENER

Your opener can be activated by any of the following devices:

• The Lighted Door Control Button.

Hold the button down until door starts to move.

• The Outside Keylock or Keyless Entry System 

(if you have installed either of these accessories). 

• The Remote Control Transmitter. 

Hold the push button down until the door starts to move.

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 per-
sonal injury could result.

The door can be opened manually by pulling the release handle down and back (toward the opener). To reconnect the door, pull the release handle
straight down.

Do not use the manual release handle to pull the door opener or closed.

When the Opener is Activated by Remote Control or Lighted Door Control Button:

1. If open, the door will close. If closed, the door will open.

2. If closing, the door will reverse. 

3. If opening, the door will stop (allowing space for entry and exit of pets and for fresh air).

4. If the door has been stopped in a partially open position, it will close. 

5. If an obstruction is encountered while closing, the door will reverse.

6. If an obstruction is encountered while opening, the door will stop. 

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 4-1/2 minutes. Bulb size is 40 Watts maximum.
