Chamberlain 1425E User Manual

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.
• If one control (force or travel limits) is adjusted, the other
control may also need adjustment.
• After ANY adjustments are made, the safety reversal system
MUST be tested. Door MUST reverse on contact with 38 mm
high object on the floor.
To prevent damage to vehicles, be sure fully open door
provides adequate clearance.

ADJUSTMENT STEP 1
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
orange buttons. Black moves the door UP (open) and
orange moves the door DOWN (close).
Setting the UP position:
1. Press and hold the black button until the LED starts
flashing slowly, then release (Figure 2).
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 (Figure 3).
4. Immediately when the door begins to close, press and
release either the black or orange button. This will stop
the door.
Setting the DOWN position:
5. Push and hold the orange 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 orange buttons to reach the
desired closed position.
7. Push the door control or programmed remote control.
This sets the DOWN (close) limit and the door should
open.
Proceed to Set the Force.
