If you have issues pairing, please check the following:

• Activate Bluetooth on your smartphone.
• Hold your device close to your phone and try again.
• Make sure you enable pairing on the health watch, by tapping the pairing symbol.
• Make sure no other devices are nearby, to avoid interference.
• Make sure the devices’ battery is charged.
• If pairing worked before, remove 'Philips health watch' from your Bluetooth menu, in settings, and try to pair the device again.

If non of the above solve your problem, please contact Philips Consumer Care.
