How to Change the Batteries in a Vent

To change the batteries in the vent, follow these steps below:

  • Remove the middle magnetic faceplate from the vent
  • Remove the battery pack by lightly pressing on the middle tab towards the battery pack
    • The battery pack may begin to lift out after doing so
    • Be careful not to press the reset button next to the serial number sticker
  • Fully remove the battery pack and remove the old batteries
  • Insert the new batteries, taking care to match up the polarity properly as labeled on one side
  • Reinsert the battery pack following the arrows on the side of pack
  • Press the battery pack in until the middle tab clicks into place
    • Again, be careful not to press the reset button next to the serial number sticker
    • If the vent was previously installed, you should see the LED flash once only and no calibration will occur
    • If the vent was previously reset (intentionally or accidentally), the vent will calibrate (open and close quickly) and result in a flashing LED
  • Return the magnetic faceplate to the device
