The battery is completely discharged to 0%, and the watch is turned on after being charged.
A factory reset has been performed on the ReadiWatch.
Complete the Calibration
When calibration is required, the ReadiWatch will display the following screen. This will also be the first screen displayed after completing a factory reset:
To complete the process:
Lift the ReadiWatch and keep it suspended in the air.
Make sure the back of the watch is completely uncovered.
Avoid touching or covering the sensors with your fingers, a wall, or any nearby object.
Keep the watch still and wait for the OK button to become active.
When the OK button turns red, press it to complete the calibration.
Important: Do not place the ReadiWatch on a surface or cover the sensors during calibration, as this could prevent the process from completing correctly
If the OK button does not become active, confirm that the sensors are completely uncovered and repeat the process while keeping the watch suspended and still.
Once calibration is complete, the ReadiWatch will display the home screen with the device serial number.
