Care and maintenance
In case the ring gets stuck on your finger:
1. Use cold water and soap and slowly twist the ring to remove it.
2. Hold your hand up above your heart until the blood pressure lowers and then
try to remove your ring.
In order to clean your ring, use a soft cloth or hand wash with mild soap and water.
Keep the ring away from children. Do not leave the ring exposed to heat, such as in a
vehicle under the sun.
The changeable Outer-shells may get scratches against harder metal jewelry or
other objects in close contact made of harder materials.
Like with all rings made of metals, be careful when handling batteries when you are
wearing the ring. If the electrodes of a battery are in contact with the ring, the
battery may short circuit.
Determining your current battery level
You can check the level of your battery by logging into your Circular app and looking
at the top-right corner of the home page. If your ring is on the charger and is fully
charged, the charger LED will be off.
IMPORTANT NOTE: If your ring has reached 0% battery, please connect to your ring
with the app. If you don't do it, your ring won't acquire data.
