Calibrating ReadiWatches

When will a ReadiWatch require calibration?

The ReadiWatch will require calibration under two circumstances:

  1. A ReadiWatch’s battery has depleted to 0%. Then, the ReadiWatch has been charged and powered on.

  2. A ReadiWatch has been factory reset.

How to complete the ReadiWatch calibration process

Once the ReadiWatch is powered on and displays the below screen, complete the following steps:

  1. Lift and hold the ReadiWatch in the air.

  2. Ensure that the back side of the ReadiWatch is not covered by any objects, such as your hand.

  3. Wait for the OK button to turn red.

  4. Tap on the OK button.

That’s it, the ReadiWatch calibration process has been completed. Your ReadiWatch should now display its start screen with the device’s Serial Number.
