Philips does offer instructions for its universal remote controls as of 2015. An instruction sheet is included in the product packaging. Philips.com also provides instructions for its products.
From the Philips homepage, click Product Support under the For Consumers menu, then enter your product code. A link appears to allow you to download the manual. The product code is on the back of your remote control and is two or three letters followed by a series of numbers.
The Philips website also provides a tool to find codes for programming your remote control under the Remote Control Code Finder tab on the product page.
