The ATA PTX4 was upgraded to version 2 using more modern surface mount technology & the pink version was introduced for a short term (now very hard to find).

A good coding video is at:- https://www.youtube.com/watch?v=r-O1Kz0l_7k
We have a compatible remote called PRESTIGE MAJESTIC which is electronically the same in a more cost effective & robust metal case with a sliding button protector.
Due to local interference on the legal 433.92Mhz band the limited run ATA PTX4 Green Button 304MHz version was release - but was never supported in the marketplace with spares.
