USING YOUR GARAGE DOOR OPENER
Your opener can be activated by any of the following devices:
• Open control panel: Up and Down Buttons.
• The Outside Keyswitch 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 personal
injury could result.
The door can be opened manually by pulling the release
handle down. To reconnect the door, pull the release handle
down and toward the opener.
Do not use the manual release handle to pull the door
open or closed. When the Opener is Activated by Remote
Control:
1. If open, the door will close. If closed, the door will open.
2. If closing, the door will stop.
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 or closed
position, it will reverse direction.
5. If an obstruction is encountered while closing, the door will
reverse.
6. If an obstruction is encountered while opening, the door will
reverse and 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.
The opener lights will turn on under the following conditions:
when the opener is initially plugged in; when power is restored
after interruption; when the opener is activated or when the IR
Beams are triggered with the door in the Open position.
They will turn off automatically after 2-1/2 minutes or provide
constant light when the Light feature on the LCD Motion
Detecting Control is activated. Bulb size is E27. Bulb power is
40 watts maximum.
To prevent possible SERIOUS INJURY or DEATH:
• NEVER allow small children near batteries.
• If battery is swallowed, immediately notify doctor.
