  1. These systems do not have a changeable Bluetooth name so we recommend only having one system per house otherwise you will see multiple devices with the same name. In some cases you can re-name the Bluetooth on your phone however this is phone specific so please check on your device first.

  2. These systems do NOT require a PIN code so therefore can be connected to your Alexa or Google Home via Bluetooth. Please ignore any reference to PIN codes in the manual, product has been updated & improved.
