How can I tell if the battery is depleted on my Snuza Monitor?

If the Snuza® Battery Indicator Light shows that the battery is depleted or nearing depletion (flashing orange or red), do not use the monitor again until you have replaced the battery.
For all Snuza products that use CR2 batteries, we recommend only using Energizer and Duracell primary CR2 batteries (3V).
