The Remote Control Battery To prevent possible SERIOUS INJURY or DEATH: • NEVER allow small children near batteries. • If battery is swallowed, immediately notify doctor. To reduce risk of fire, explosion or chemical burn: • Replace ONLY with 3V2016 or 3V2450 coin batteries. • DO NOT recharge, disassemble, heat above 100° C (212° F) or incinerate. The 3V2016 lithium batteries for the opener and LED lights (marked "LED and Opener Battery") should last 5 years. The 3V2450 lithium battery for the proximity lighting (marked "Proximity Battery") should last 1-2 years. To replace the batteries, remove the two screws and open the remote control housing. Push the battery out of the holder for removal. Insert replacement batteries positive side up. Dispose of old batteries properly. Replace the batteries with only 3V2016 or 3V2450 coin cell batteries. LED and Opener Batteries Proximity Battery Spring Contact CAUTION: Do not bend spring contact. If bent the proximity sensor will not work. Troubleshooting PROBLEM SOLUTION Reduced proximity sensing (does not activate by touching top of remote control) Check if proximity lighting is disabled by pressing a button. The Proximity Sensor may be oversensitized. Sit remote control undisturbed for 60 seconds on a non-metallic surface. This allows the sensor to recalibrate itself.
