A method for producing a ceramic heater. The heating device of the present invention having the foregoing structure permits the object to be heated in a short period time and shows excellent properties in terms of the saving of energy and the suppression of noise sound. The transmitter controller also generates at least one forward error correction codeword from the identification data and the command data. There is also a user-actuatable releasing actuator for releasing the locking mechanism. Based on this zone and sector assignment the UWB device may select communication parameters for communication with other UWB devices.
