Make no mistake, this is a VINTAGE remote and probably only a collector of electronic antiquities or a gamer who likes to use a tube television for their retro gaming (yes, many do this!) will have the television that this "talks" to ...
I cannot "pin down" the exact model television/vcr that this remote was designed to be used with but it was definitely a CRT (picture tube) type of television, not LCD or Plasma and it also controls an associated VCR (built in to the television possibly)
In fact it could well be that MANY televisions from Philips MAY be controllable by this remote because it uses the RC-5 communications protocol, originally developed by Philips to provide a "standard" for consumer electronics remote communications.
There remains even to this day quite a bit of interest in the RC5 protocol (search on Google RC5 PROTOCOL) with some even producing RC5 decoders based on Arduino systems, see HERE
I would hazard a guess that this remote was developed and released to the market in the early 1980's
PHILIPS Remote Control SPARE PART
Retro model early 1980's
USED InfraRed Remote control
Genuine PHILIPS product NOT a 3rd party copy
Claim to fame: RC-5 Protocol transmissions
Part number: 5311 4822-218-20516
TWIN IR Led emitting diodes
Construction: Brown plastic with a Champagne metallic top surface
Requires 4x AAA batteries (NOT supplied)
COSMETIC CONDITION
USED
CLEAN
All labelling is clean, easy to read and not worn
All buttons functioning great!
Battery compartment is in excellent condition with NO corrosion to the battery terminals
TESTED and functioning fine on ALL buttons
NOTE: My testing method is to insert batteries and "look" for the IR emissions from the remote control (easily viewed on the security camera's) and ensuring every single button sends out an IR code. I must assume though that the codes being sent are correct, I do not have one of these old Philips CRT televisions and have not built the decoder!
Stored/supplied in a sealed plastic to maintain its condition
The batteries will NOT be supplied as Australia Post is a bit touchy about such things being sent through the Post. These batteries are nothing special and usually low cost (Alkaline type will be fine)
