Welcome!Your journey to better health starts here.
This startup guide will take you through all the steps to setup your Circular ring and App.
01. getting started
Setup your Circular ring with your charger.
Charge your ring
You just received your new Circular Ring, congrats! You first need to wake it up by placing it on the charger and charge your ring to 100%. To do so, you need to take out the charger and place both magnetic pins on those located on your ring.
You can plug the charger into a power source (laptop, power bank, phone...). The connector needs to be USB-C.
Look out for the charger's LED
The LED of the charger will fade in and out when the ring is charging and the LED will turn off when the battery of the ring is full.
02. APP and use
Start using your Circular Ring.
Install the app
Search for "Circular ring" on the App Store or Google Play. Once dowloaded, follow the instructions to create an account and to pair your ring!
Wear the ring 24/7
Once you have a ring paired with your account, you are all set! The ring will automatically start tracking your metrics as soon as it detects that you are wearing it. Don't forget that the ring is waterproof up to 5 meters. The Circular ring can be worn in a shower, sauna, or when swimming.
03. wear instructions
How to wear your ring
You can wear Circular on any finger except the thumb. It is best to wear Circular on the fingers of your non-dominant hand. Eg: If you are right-handed, wear it on your left hand. The three middle fingers give the most accurate readings.
The flat part of the ring should be towards the palmar side of your hand.
The button of the ring should be accessible with your thumb.
USE In case the ring gets stuck on your finger:
1. Push the bottom of your ring towards your finger, it should create a space above your finger, between your finger and your ring. Then pull the ring to tak it out while continuing to press towards your finger.
2. Use cold water with soap or gel and slowly twist the ring to remove it. 3. Hold your hand up above your heart until the blood pressure lowers and then try to remove your ring.
Watch out, finger size can vary through the day, your fingers may swell in the morning or evening!
Care and maintenance
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.
It is not recommended to use the ring when carrying weight. Damage may occur to the ring and button.
The button must be pressed with human finger only.
Determining your current battery level
You can check the level of your battery in two ways. 1. By logging into your Circular app and looking at the top-right corner of the home page. 2. 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 the app to your ring before wearing it. If you don't, your ring won't acquire data.
Charging your Circular ring
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. The Circular ring is held magnetically to the charger. To charge your Circular ring:
1. Place the magnetic contact pins from your Circular ring on the charger’s pins. 2. Plug the charger dongle into a USB-C port on your computer or an adaptor on any plug. 3. If charging works then the led of the charger should blink. Your ring is fully charged when the led stops blinking. Some pro tips for charging success: 1. Try placing the ring on the charger first, then plugging in the USB port. If you do not see the LED come on, try lightly moving the ring on the charger.
2. Try taking the ring off the charger and then putting back.
3. If you still do not see the LED, try flipping the ring 180 degrees (like spinning a penny, not rotating like a wheel) so the opposite charging contact connects. If you still do not see the LED, try cleaning the contact pins of your charger and your ring using warm water and soap, then drying with a soft cloth.
4. If you still do not see the LED, try a different power source or other adapter/charger.
5. When charging a Circular device using a wall outlet, it is recommended that a premium brand AC adapter should be used. Some off-market adapters will prevent the ring from reaching the charging state.
6. Charge your ring at room temperature. Avoid charging in your cold car, garage, or a room that is too hot.
7. After a firmware update, the battery display in your Circular app can be off. To make sure the displayed battery charge is accurate, please fully charge your ring again.
