GREEN LED: All systems are normal.
• A solid LED light indicates the battery is fully charged.
• A flashing LED indicates the battery is being charged.
NOTE: Battery does not have to be fully charged to

ORANGE LED:
The opener has lost mains power and is operating on
battery power.
• A solid LED with beep, sounding approximately every
2 seconds, indicates the opener is activating the door
and is operating off the battery.
• A flashing LED with beep, sounding every 30 seconds,
indicates battery is low.
• Once the power is restored the battery will recharge.
This is indicated by a flashing green LED.
RED LED:
• If a red LED remains on when the power is restored,
and is accompanied by a beep sounding every 30
seconds, replace the battery and allow 48hrs for it to
fully charge. If the RED LED remains on after this time
contact a qualified door technician.
Charging the battery.
• Battery will take 24 to 48 hours to fully charge.
A fully charged battery supplies 12V DC to the opener
for one to two days of normal operation during an
electrical power outage. If the battery voltage drops too
low, the battery will disconnect and the opener will no
longer operate under battery power.
After the electrical power has been restored, the battery
will recharge within 48 hours. Under normal usage
batteries will last 3 to 5 years.
To obtain maximum battery life and prevent damage,
disconnect the battery when opener is unplugged for
an extended period of time.
NOTE: Door operation may be limited until battery is
fully charged. The opener's lights will not turn on
during battery mode.
