TEST THE BATTERY

1. Unplug the garage door opener. The battery status LED will either glow
solid orange indicating opener is operating on battery power or will flash
indicating low battery power. NOTE: Make sure the garage door opener is
unplugged.
2. Open and close the door using the remote control or door control. The
garage door opener may run slower if the battery is not fully charged. The
battery will take 24 hours to fully charge.
3. Plug in the garage door opener. Verify the battery status LED is flashing
green, indicating the battery is charging.

CHARGE THE BATTERY

The battery charges when the garage door opener is plugged into a 110Vac
electrical outlet that has power and requires 24 hours to fully charge. A fully
charged battery supplies 12Vdc to the garage door opener for one to two days of
normal operation during an electrical power outage. After the electrical power has
been restored, the battery will recharge within 24 hours. The battery will last
approximately 1 to 2 years with normal usage. Instructions for replacement are
provided with the battery. To obtain maximum battery life and prevent damage,
disconnect the battery when the garage door opener is unplugged for an extended
period of time, such as a summer or winter home.
NOTE: When the garage door opener is in battery backup mode the garage door
opener lights, Timer-to-Close, and Remote Close features are unavailable.
To reduce the risk of FIRE or INJURY to persons:
