Sky toro esc/program box issues

[ChrisCorbett]

Anyone else running these? I can't get the program box to connect to the esc. I've calibrated the radio and now want to program the esc via box but it keeps saying connection failure.
I've connected it as per manual; servo lead connecting box to the 3 pins on side of speedo, Esc plugged into receiver and radio on.
When I power up it show the scrolling menu but when I select esc settings it says connection failure. Also I can't see anywhere in manual about programming without box, is this correct?
