little Circle Icon in the upper LEFT hand corner at the TOP, turns it on , at the very Bottom of the Device is the OFF switch.
I installed mine so I could use the shift number keys, to pull it up, just like other pop up panels, works fine.
I tried the Icon on the panel instructions , but I couldn't get it to show, tho what I really was wantin was the Icon on the VC Panel, but I'm happy the way I have it set up in my highly customized Grumman Goose G21A / FSX, with custom Night Lighting and customized Dash and Custom interior and sounds , thanks to the guys over at OZ X for their works and a few of my own tweaks as well, its awsum , now I've got 22 really nice G21A Gooses !!
Tested out "FLYPAD", and I kinda like it, actually, gives ya wind speed, Terrain, TWAS, all kinds of Gizmo's and Gadgets to use while flying !
it works like its supposed to, tested and tried , I like it and best part is its - FREE !!!!
