There's no need to panic if you've lost the codes for your Phillips PH301S universal remote controller. Plenty of online sites offer the codes, or copies of the manual for this type of remote. Try download.p4c.philips.com first, as this site provides PDFs for the manual of your PH301S remote.

Philips Customer Care
Of course, you could try contacting Philips themselves. Their general helpline is 0844 338 0489, but for TV accessories like remotes, try 1-866-309-7730. Their website also offers access to manuals and general support.
