Feature Overview

LIGHT BUTTON

Press the LIGHT button to turn the garage door opener lights on or off. When the lights are turned on they will stay on until the LIGHT button is pressed again, or until the garage door opener is activated. Once the garage door opener is activated the lights will turn off after the specified period of time (the factory setting is 4-1/2 minutes). The LIGHT button will not control the lights when the door is in motion.

MOTION SENSOR

The motion sensor will automatically turn on the garage door opener lights when motion is detected. The lights will come on for the set period of time, then shut off. The factory setting is on and set at 4-1/2 minutes.

LOCK

The LOCK feature is designed to prevent activation of the garage door opener from remote controls while still allowing activation from the door control and keyless entry. This feature is useful for added peace of mind when the home is empty (i.e. vacation).

• ALWAYS keep garage door in sight until completely closed. NEVER permit anyone to cross path of closing garage door.

MAINTENANCE ALERT SYSTEM (MAS)

This feature assists the homeowner in ensuring the garage door opener system stays in good working condition. The MAS feature MUST be activated at time of installation. The factory setting is off. The service LED will come on after 4500 garage door opener cycles. This indicates the garage door opener may need maintenance; contact your installation dealer. If the MAS feature is activated, the command LED (yellow) and the service LED (red) will alternate flashing back and forth.

TIMER-TO-CLOSE (TTC) FOR MODEL 881LM ONLY

DO NOT enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors. The TTC can be set to automatically close your garage door after a specified period of time (1, 5, or 10 minute intervals). The garage door opener will beep and the lights will ﬂ ash before closing the door. If the door encounters an obstruction while closing, the garage door opener will make a second attempt to close the door. If the obstruction has not been cleared after the second attempt, the garage door opener will reverse open, stop and WILL NOT close until the obstruction has been cleared. TTC WILL NOT work if the garage door opener is operating by battery power or if the safety reversing sensors are misaligned. This feature is NOT intended to be the primary method of closing the door. A keyless entry should be installed in the event of an accidental lock out when

using this feature.
