Program the Travel Limits

Travel limits regulate the points at which the door will stop when moving up or down.
Adjust the position of the door by using the black and yellow buttons. Black moves the
door UP (open) and yellow moves the door DOWN (close).
NOTE: The yellow command LED and the red learn LED will blink quickly for up to
5 minutes as the control panel recharges. When the control panel is operational, the
yellow command LED will glow steadily.
SETTING THE UP POSITION:
1. Press and hold the black button until the LED starts flashing slowly, then release.
2. Push and hold the black button until the door reaches the desired UP (open)
position.
NOTE: Make sure the door opens high enough for your vehicle.
3. Push the door control or programmed remote control. This sets the UP (open) limit
and begins closing the door.
4. Immediately when the door begins to close, press and release either the black or
yellow button. This will stop the door.
SETTING THE DOWN POSITION:
5. Push and hold the yellow button until the door reaches the desired DOWN (closed)
position.
6. Once the door is closed, if there appears to be too much pressure on the door, you
may toggle the door back and forth using the black and yellow buttons to reach the
desired closed position.
7. Push the door control or programmed remote control. This sets the DOWN (close)
limit.
Proceed to Set the Force.

Without a properly installed safety
reversal system, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
• NEVER learn forces or limits when
door is binding or sticking. Repair
door first.
• Incorrect adjustment of garage
door travel limits will interfere with
proper operation of safety reversal
system.
• After ANY adjustments are made,
the safety reversal system MUST
be tested. Door MUST reverse on
contact with 1-1/2" high (3.8 cm)
object (or 2x4 laid flat) on floor.
To prevent damage to vehicles, be
sure fully open door provides adequate
clearance.
