Frequently Asked Questions I forgot my PIN for the Theft Deterrence Function. What can I do? The Philips Service center has the right to ask for legitimate identification and authorization in order to establish ownership of the monitor. Please note that the theft deterrence function is provided as a convenient free option. Managing PINs is the sole responsibility of the individual user or the organization that sets them. If the PIN is forgotten, the Philips service center can reset it for you at a nominal charge after verification of ownership. Please note that this is not covered by standard warranty terms.
