The opener is supplied with a three-button remote control (the second and third buttons can be used to
control additional openers or gates). Additional single and multi-button remote controls can be purchased.
The short wire on the back of the opener serves as an antenna for the remote controls. Do not cut off the wire
or the remote controls will not operate well.
To Add or Remove a Remote Control
1 Press the opener’s LEARN button. The opener’s
light and red light will flash once and turn on for
about 15 seconds. A remote control must be
added or removed while the red light is still on.
2 Send a signal from a remote control. The opener’s
light and the red light will flash once if a remote
control was added, or the opener’s light and the
red light will flash four times if a remote control
was removed.
3 Repeat Steps 1 & 2 for any additional remote
control controls.
To Remove All Remote Controls
1 Press and hold the opener’s LEARN button for
ten seconds or more.
2 Release the LEARN button. The red light and
opener’s light will blink three times signaling that
all of the remote controls in the opener’s memory
were erased. The red light will turn off, then turn
on for 15 seconds. A remote control can be
entered during this time using the steps above.
Testing
1 Before testing the remote control, straighten out the opener’s antenna wire so it points up.
2 Stand clear of the door, press the remote control’s button and verify that the opener starts. PRESS THE
REMOTE CONTROL’S BUTTON AGAIN TO STOP THE DOOR MID-TRAVEL.
Replacing a Remote Control’s Battery
When the blue light on the remote control glows
dimly, or fails to light at all when the remote
control is activated, the battery needs replacing.
Follow the steps in the diagram and use caution
to keep batteries away from children.
Replace old battery with a fresh CR2032 Lithium
battery.
Properly dispose of old batteries. Many
electronic stores and supermarkets have battery
recycling bins.
Never dispose of batteries in fire because they
could explode.
