The product has a 4-digit PIN code which is activated from factory. When you receive your product, you will also get the factory PIN code from your Bang & Olufsen retailer.
The PIN code must be entered if the product has been disconnected from the mains for 15 to 30 minutes. This means that if a product is removed from your house and thus disconnected, it cannot be used until the correct PIN code has been entered.
You can change the PIN code at any time to a 4-digit code of your own choice. Please refer to the product's user guide.
The Master code is required if you forget the PIN code and is only available via an authorised Bang & Olufsen retailer.
