To pair Alexa with Caavo, first you'll need to add the Caavo skill to your Alexa account. Search for Caavo in the skills section of the Alexa app, and then add Caavo as a skill. Once you've done that, follow these steps...
1. Press the Caavo button
2. Go to Settings > Other Services > Alexa
3. Follow the on screen instructions for your Caavo
Next, tell Alexa your PIN, in this case it's 7788: "Alexa, tell Caavo my PIN is 7788". Caavo should now be paired, and you can try things like "Alexa, tell Caavo to open Netflix".
Please note that the PIN will be different each time you need to re-pair Caavo to Alexa.
