ADJUSTMENT STEP 1
Program the Travel Limits
Travel limits regulate the points at which the door will
stop when moving up or down. Follow the steps below
to set the limits.
To program the travel limits:
Adjust the position of the door by using the black and
purple buttons. Black moves the door UP (open) and
purple moves the door DOWN (close).
1.
Setting the UP position:
Press and hold the black
button until the yellow indicator light starts flashing
slowly then release.
2. Push and hold the black button until the door reaches
the desired UP (open) position (Figure 2).
NOTE:
Check to be sure the door opens high enough for
your vehicle.
3. Push the remote control or door control (Figure 3). This
sets the UP (open) limit and begins closing the door.
4. Immediately when the door begins to move down, press
and release either the black or purple button. This will
stop the door.
5.
Setting the DOWN position:
Push and hold the purple
button until the door reaches the desired DOWN
(closed) position (Figure 4).
6. Once the door is closed, if there appears to have too
much pressure on the door, you may toggle the door
back and forth using the black and purple buttons to
reach the desired closed position.
7. Push the remote control or the door control (Figure 3).
This sets the DOWN (close) limit and should bring the
door to the open position.
•
If the opener is not stopping exactly where you would
like it, repeat steps 1 through 7 and program the limits
again
.
• When the unit stops in both the desired up (open) and
down (close) positions, proceed to
Adjustment Steps

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