Using Your Garage Door Opener
Your opener will operate with up to twelve remote
control transmitters, one entry keypad, and one dip-
switch code transmitter. If you purchase a new
remote, or if you wish to deactivate any remote,
follow the instructions in the Programming section.
Activate your opener with any of the following:
The hand-held Remote Control: Hold the large
push button down until the door starts to move.
The wall-mounted Door Control: Hold the push
button down until the door starts to move.
The Keyless Entry (Optional): Must be
programmed before use.
When the opener is activated:
1. If open, the door will close. If closed, it will open.
2. If closing, the door will stop and reverse.
3. If opening, the door will stop.
4. If the door has been stopped in a partially open
position, it will close.
5. If obstructed while closing, the door will reverse. If
the obstruction interrupts the sensor beam, the
opener lights will blink for five seconds.
6. If obstructed while opening, the door will stop.
7.
If fully open and the Infrared Safety Reversing
Sensor is installed, the door will not close when
the beam is broken. The sensor has no effect in
the opening cycle.
The opener light 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.
It will turn off automatically after 2-1/2 minutes. Globe
power is 40 watts maximum.

1. READ AND FOLLOW ALL WARNINGS AND
INSTRUCTIONS.
2. ALWAYS keep remote controls out of reach of children.

closed. NO ONE SHOULD CROSS THE PATH OF THE
MOVING DOOR.

broken springs or unbalanced door could result in an
open door falling rapidly and/or unexpectedly.
6. NEVER use emergency release handle unless garage
doorway is clear of persons and obstructions.
7. NEVER use handle to pull garage door open or closed. If

other control may also need adjustment.

system MUST be tested.

reverse when required and could result in severe injury
or death.

hardware, all of which are under EXTREME tension,
MUST be made by a trained door systems technician.
13. ALWAYS disconnect electric power to garage door
opener before making any repairs or removing covers.
