IMPORTANTINFORMATION ABOUTTHE SAFETYREVERSING
SENSORS
The safety reversingsensors must be connected and aligned
correctly before the garage door opener will move in the
down direction,
The sending sensor (with an amber LED)transmits an invisible
light beam to the receiving sensor (with a green LED). If an
obstruction breaks the light beamwhile the door is closing, the
door will stop and reverse to the full open position, and the
garage door opener lights will flash 10 times.
NOTE: For energy efficiency the garage door opener will enter
sleep mode when the door is fully closed. The sleep mode shuts
the garage door opener do wn until activated. Thesleep mode is
sequenced with the garage door opener light bulb; as the light
bulb turns off the sensor LEDs will turn off and whenever the
garage door openerlights turn on the sensor LEDs will light. The
garage door opener will not go into the sleep mode until the
garage door openerhas completed 5 cycles upon power up.

• Sensors are installed inside the garage, one on either side of
the door.
• Sensors are facing each other with the lenses aligned and the
receiving sensor lens does not receive direct sunlight.
• Sensors are no morethan 6 inches (15 cm) above the floor
and the light beam is unobstructed.
Be sure power is NOTconnected to the garage door opener
