The warranty period starts on the date of purchase as stated on your proof-of-purchase and expires at the end of the period indicated in the section “Warranty period” above. If you require service but you lost your proof-of-purchase or the retailer is unknown to Philips (e.g. a seller on an on-line auction channel), the warranty period shall be deemed to have started three months from the date of manufacture indicated on the product or derived from the serial number. If you require service for products without production date or serial number on the product a valid proof-of-purchase is required.
Where a repair is not possible or not commercially viable, Philips may arrange for a new or refurbished product of similar functionality, or do a refund up to full purchase price of the product plus tax (subject to terms and conditions). After a repair, firmware upgrade or replacement the warranty period will continue from the date of the original purchase.

The warranty does not cover consequential damages (including but not limited to loss of data or loss of income), nor compensation for activities done by yourself, such as regular maintenance, installing firmware updates or saving or restoring data.

The warranty excludes, or does not apply:
If the proof-of-purchase has been altered in any way or is made illegible.
If the model number, serial number or production date code on the product has been altered, removed or made illegible.
Damage caused by service performed by anyone other than Company Approved Service Location.
If the defect is the result of excessive use outside the intended purpose, e.g. non-stop use in a commercial environment.
If the defect is caused by abuse of the product or by environmental conditions that are not in conformance with the user manual of the product.
If the defect is caused by connecting peripherals, additional equipment or accessories other than those recommended in the user manual.
If the unit has been damaged, including but not limited to damage by animals, lightning, abnormal voltage, fire, natural disaster, transportation or water (unless the user manual expressly states that the product may be rinsed).
To third party applications used on- or with your products.
