When setting up your system for the first time, you will need to set up the Baby monitor and Parent wristband.
You will need to keep both the devices on their charging stations on the Smart hub and make sure that they are charging with Blue lights on.
Then you will need to use your app set-up process to scan the QR codes for the devices, which can be found on the quick start-up guide or on the bottom of the Smart hub. This will then add the devices to your account.
