Unfortunately, I'm not aware of a specific product called "Tandberg 14." Please provide further context or details to help me identify the product you're referring to. Is "Tandberg 14" the model number of a Tandberg-brand product? If so, what type of product is it (e.g. Video conferencing system, digital signage player, etc.)? Once I have this information, I'll be better equipped to provide you with helpful assistance.
