Never having used rc before I have successfully run a test rig for the motion pack for my KT and am now moving on to the sound system.

I am using the Futaba 7c supplied by Mark and Gill and in the instructions booklet Mark says to refer to the Futaba handbook as to how to set the 3 way switch to channel 6. In my igorance I have not found anything in the handbook that refers to this.

I am assuming that the three way switch is the one on the top left of the transmitter lettered E but would welcome some very simple step by step advice as to how to set this to control channel 6. Can someone help please?
