Features

Your garagedoor opener is equippedwith features to provide you with greater control over your garagedoor operation.

TIMER-TO-CLOSE

The Timer-to-Close feature automatically closes the door after a specified time period that can be adjusted using the door control. Prior to the door closing there will be an audible and visual alert.

ASSURELINKTM

AssureLinkTM technology uses a 900MHz signal to provide two-way communication betweenthe garage door opener and AssureLinkTM accessories. Your garagedoor opener is compatible with up to 8 AssureLinkTM accessories.

REMOTECONTROLSAND DOORCONTROLS

Your garagedoor opener is compatible with up to 2 door controls. Your garagedoor opener has already been programmed at the factory to operatewith your remote control, which changes with each use, randomly accessing over 100 billion new codes. The garage door opener is compatible with up to 8 remote controls and 1 keyless entry.

THE PROTECTORSYSTEM® (SAFETYREVERSINGSENSORS)

When properly connected and aligned, the safety reversing sensors will detect an obstruction in the path of the infrared beam. If an obstruction breaks the infrared beamwhile the door is

closing, the door will stop and reverseto full open position, and the opener lights will flash 10 times. If the door is fully open, and the safety reversingsensors are not installed, or are misaligned,

the door will not close 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 is fully closed. The safety reversing sensors do no effect the opening cycle.

ENERGYCONSERVATION

For energy efficiency the garagedoor 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

sequencedwith the garage door opener light bulb; as the light bulb turns off the sensor LEDswill turn off andwhenever the

garage door opener lights turn on the sensor LEDswill light. The garage door openerwill not go into the sleep mode until the garage door opener has completed 5 cycles upon power up.

LIGHTS

The garage door opener light bulbs will turn on when the opener is initially plugged in; power is restored after interruption, or when the garagedoor opener is activated. The lights will turn off automatically after 4-1/2 minutes. An incandescentA19 light bulb (100 watt maximum) or for maximum energy efficiency a 26W (100W equivalent) compact fluorescent light (CFL)bulb may

be used.

The garage door opener is equipped with an addedfeature; the lights will turn on when someone enters through the open garage door and the safety reversing sensor infrared beam is broken. For addedcontrol over the light bulbs on your garage door opener, see the Door Control section.
