Chime Indication

When powered on, the Neurio W2 will play the following tones to indicate its status in sequential order.

Tone	Indication	Description

Pairing Behavior

How long can a Neurio meter remain powered on to accept pairing requests?

If the meter has never been paired, or if it was previously paired and then unpaired gracefully during device setup, the meter will remain on and accept pairing requests indefinitely. It will reboot every 30 minutes.

If the meter has been previously paired and was not unpaired gracefully during device setup, the pairing process must begin within 1 minute of bootup (audible chime).
