Procedure depends on your filter type.
- Install the new filter. Ensure proper insertion: line up the filter groove with the reservoir ridge. Press firmly.
- Reset the indicator.
- For a standard white filter (OB03): Press and hold the STATUS button for 2 seconds. Release. All lights blink twice, then the green STANDARD FILTER light blinks three times.
- For a blue LONGLAST+ filter (OB06): Press and hold the STATUS button for 6 seconds. Release when the green LONGLAST FILTER light has blinked three times.
IF THAT DIDN'T WORK: You selected the wrong mode. Repeat step 2, holding for the correct duration for your filter color. Ensure the fill lid is closed during reset.
HEADS UP: For accurate filter life tracking, always fill the reservoir to the Max Fill line and open the lid only when adding water.
