Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLYINJUREDor
KILLEDby a closing garage door.
* Incorrect adjustment of garage door travel limits will interfere
with proper operation of safety reversal system.
* NEVERuse 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.
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. Settingthe 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.
NOTE:Excessivemovement of the motor unit will cause
premature wear. See Troubleshooting section.
4. Immediately when the door begins to move down, press and
releaseeither the black or purple button. This will stop the
door.

until the door reaches the desired DOWN (closed) position

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 (Figure 3). This sets the DOWN
(close) limit and should bring the door to the open position.

(close) positions, proceed to Adjustment Step 2,
