Hi,

I have 2 T4YF-2.4G TX's and 2 R2004GF RX's (came with the TX's) but am unable to link either, tried cross matching. When I press & hold the link switch I get a flashing red light. I have held it as close as I can, at a distance < 1m and have turned of home router. All makes no difference. Any ideas before I find the bin. Many thanks.
