If the screen of your Withings Pulse™ Ox doesn't turn on:
- Charge it for at least two hours.
Try using a USB cable you know is working to make sure the issue doesn't come from the cable that comes with the device.
- After charging it, press the button for 15 seconds.
At this point, it can take up to a minute for your Withings Pulse™ Ox to start.
When it does, "hello" is displayed on the screen.
