      If the info code REVERSE is flashing, it means the meter is installed with water flowing in the wrong direction. Remount the meter following the flow arrow located on the side of the meter case.

      The info code DRY flashes because the meter is not water-filled. To resolve this, air the installation. The info code will disappear once the meter is filled with water.

      The info code RADIO OFF flashes because the meter is still in transport mode with the built-in radio transmitter turned off. This info code disappears, and the radio switches on, after the first ½ liter of water has run through the meter.
