2 - CHARGE

• The green LED is solid while charging
• A full charge takes up to 2 hours
• The FYER is fully charged when the green LED stops and goes into advertising mode (blue LED blinking)
• You can measure up to 24 hours on a full charge.
• When the blue LED is blinking, the FYER advertises, this stops when you insert the charging cable.
• The FYER resets when you plug in the charging cable.

3 - GET STARTED

• Make sure you're charged (you, and your battery).
• When the blue led is blinking the sensor is on and ready to connect

4 - PLACE THE SENSOR

The FYER can be worn everywhere on your body and the app currently saves 8 locations. Select and connect your sensor in the 'connect sensor' section of the smartphone app. You can connect up to 4 Fyer's and 1 HR sensor at once.

How to strap the sensor:
- Choose the right strap length
- Position the sensor directly on your skin, and place it on the belly of your muscle for maximal results.
- Pull the strap nice and tight, but do not compress your skin.
- OPTIONAL: Standardise placement and protect from ambient light with the Train.Red patch (*do not use if you're allergic to physiotape)
- Check your sensor placement with our position check in the app

Note: never place your sensor over a tattooed area

  And some extra information e.g. battery status, temperature data, time stamps and BLE quality.
