A deflection yoke includes a horizontal deflection coil, a vertical deflection coil, an insulating frame made of an insulating material, a deflection adjusting plate attached to an outer circumferential surface of the insulating frame, and a ferrite core covering at least a part of an outer circumference of the insulating frame. A local device having a local channel table operates on a common channel in a multi-channel wireless network having a plurality of network devices to perform management, control, and discovery functions using a single radio. A display mode of an active application is determined by the framework. The device still further comprises a temperature control system communicatively coupled to the control unit and configured to receive the temperature-setting signal and maintain the MEMS oscillator at the selected operation temperature.
