(SAFETY REVERSING SENSORS)
When properly connected and aligned,the safetyreversing sensors will detect an obstruction in the path
of the infrared beam.Ifan obstruction breaksthe infrared beam while the door is closing, the door will
stop and reverse to full open position,and the opener lights will flash 10 times. Ifthe door is fully open,
and the safety reversing sensors are notinstalled, or are misaligned, the door will notclose from a
remote control. However,you can close the door if you hold the button on the door control or keyless
entry until the door isfullyclosed. The safety reversing sensors do not effect the opening cycle.
ENERGY CONSERVATION
For energyefficiencythe garage door opener will enter sleep mode when the door is fully closed. The
sleep mode shuts the garage door opener down until activated.The sleep mode is sequenced with the
garage door opener light bulb; as the light bulb turnsoff the sensor LEDswill turn off and whenever the
garage door opener lightsturn on the sensor LEDs will light. The garage door opener will not go into the
sleep mode until the garage door opener hascompleted 5 cycles upon power up.
LIGHTS
The garage door opener lightbulbs will turn on when the opener isinitially plugged in; power is restored
after interruption, or when the garage door opener is activated. The lights will turn off automaticallyafter
4-1/2 minutes.An incandescent A19 light bulb (100 watt maximum) or for maximum energyefficiencya
26W (100W equivalent) compactfluorescentlight (CFL) bulb may be used. NOTE: Do not use halogen,
short neck, or specialty light bulbs as these may overheat the end panel or light socket. Do not use LED
bulbs as they may reduce the range or performance of your remote controls.

The garage door opener is equipped with an added feature;the lights will turn on when someone enters
through the open garage door and the safetyreversing sensor infrared beam is broken. For added
