So you’ve bought yourself a Turnigy 9X transmitter, turn this shiny device on and you are presented by an annoying beeping noise and “Switch Error” and first thing you do his hit google.

It’s not broken, it’s just telling you that it needs the switches all moved to the off position. Move all the switches upwards and away from you (this doesn’t include the sticks), and hey presto, no more annoying noise.  Something I found out rather quickly!
