A successful network join would be indicated by 4 green LED blinks. Remove the serial number sticker
located on the water meter, pictured above. Place the serial number sticker on the sticker sheet
supplied by ION in the correct place such as the apartment for which it is located in and in the correct
device column.
The rubber band around the water
meter is there to ensure the baby board
does not come out during delivery or
before the install!! The baby board is a
critical part !!!
