How do I replace the battery of my Snuza Monitor?

The batteries used in the Snuza® movement monitors are user-replaceable.
Remove the Battery Cover on the underside of the unit.
Remove the depleted battery.
Insert the new battery, ensuring that the polarity is correct.
Replace the Battery Cover and ensure that it is correctly closed.
Test the unit by switching on and ensuring that the Battery Indicator Light flashes green.
If the unit starts emitting a beep after the battery has been replaced, simply press the ON/OFF and MODE/OFF buttons simultaneously to turn it off.
For all Snuza products that use CR2 batteries, we recommend only using Energizer and Duracell primary CR2 batteries (3V).
