Screen
Motion
Sensor
The following features are accessible through the screen using the navigation buttons:
LEARN A DEVICE
Any compatible remote controls, wireless keyless entry, or MyQ™ accessories can be programmed to
the garage door opener by accessing the menu and using the navigation buttons.
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).
TIMER-TO-CLOSE (TTC)
DO NOT enable TTC if operating a one-piece door. TTC is to be used ONLY with sectional doors.
Factory default is set to off. TTC can be set to automatically close your garage door from the fully open
position after a specified period of time (1, 5, 10 minute intervals or a custom setting up to 99 minutes).
The garage door opener will beep and the lights will fl ash before closing the door. The screen on the
door control can display the status of the TTC. 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.
NOTE: Before enabling the TTC for the first time, or if you experience a power outage, cycle the garage
door opener open and closed to allow the TTC to set.
AUTOMATIC LIGHT
Motion Sensor
Factory default is set to on. This feature will automatically turn on the garage door opener lights when
motion is sensed. The lights will come on for the set period of time, then shut off.
The lights will turn on when someone enters through the open garage door and the safety reversing
sensor infrared beam is broken. If using the garage door opener light as a work light disable the
Automatic Light Feature, otherwise the light will turn off automatically if you are beyond the range of the
sensor.
MAINTENANCE ALERT (MAS)
This feature assists the homeowner in ensuring the garage door opener system stays in good working
condition. A maintenance alert message will display on the screen indicating the garage door opener
may be in need of maintenance. The MAS feature MUST be activated at time of installation. The factory
setting is off.
