    • A paging receiver receiving message information having one of a plurality of (BCH) code word structures has a programmable error correcting apparatus for correcting bit errors within the message information. The programmable error correcting apparatus may be configured in response to identifying a signalling system and the code word structure corresponding to ther signalling system, or in response to changes in the code word structure within the message. A simplified error correcting apparatus may correct a single bit error within a code word structure. The programamble error correcting apparatus is capable of correcting any two bit error combination within the code word structure and contains sequential and combinational logic circuits. The programmable error correcting apparatus is integrated together with a microprocessor on a monolithic integrated circuit.
    • 接收具有多个(BCH)码字结构之一的消息信息的寻呼接收机具有用于校正消息信息内的位错误的可编程错误校正装置。 可编程错误校正装置可以被配置为响应于识别信令系统和对应于其信令系统的代码字结构,或响应于消息内的代码字结构的变化。 简化的纠错装置可以纠正码字结构内的单个位错误。 编程码错误校正装置能够校正码字结构内的任何两位误差组合,并包含顺序和组合逻辑电路。 可编程错误校正装置与单片集成电路上的微处理器集成在一起。

    • A paging receiver has an indicator capable of illluminating in one of a plurality of colors. The color of illumination is selected in response to the address received by the pager. The indicator identifies the address by the color illuminated. The indicator also indicates weather a message is protected, read, about to be protected or about to be deleted by the color and color sequence of the indicator. The color indicator also indicates if the paging receiver is about to be turned off. The indicator may also serve as a back-light for a display when the paging receiver includes a display. Signals within the information to be displayed may change the color or change the intensity of the back-light, these signals may also turn the back-light off or on.
    • 寻呼机具有能够以多种颜色之一发光的指示器。 响应于寻呼机接收的地址来选择照明的颜色。 指示灯通过照明的颜色识别地址。 指示符还指示消息被保护,读取,即将被保护或将被指示符的颜色和颜色序列删除的天气。 彩色指示灯还指示寻呼机是否即将关闭。 当寻呼机包括显示器时,指示器还可以用作显示器的背光。 要显示的信息中的信号可能会改变颜色或改变背光的强度,这些信号也可能会关闭或打开背光。
