CHAPTER SwitchiR . . . . . . . . . . . . . . . . . . . . . . . . The SwitchiR is an infra-red remote control unit the size of a key fob, which can be used to access all the user-settable functions of the TX2040 and HX2040. Functions include transmitter frequency, audio level, battery status, serial number, and user identification. Control-X . . . . . . . . . . . . . . . . . . . . . . . . The Control-X uses electromagnetic induction to allow the miniTX or TX2040 transmitter to be controlled remotely, even through clothing. At a distance of up to 20cm (8") the Control-X can switch on and off the transmitter, or check and display the selected frequency, and it also provides battery check features.
