随着通信业的迅速发展,使得通信工具得到广泛的普及。BP机因具有使用方便、价格低廉等优点而成为目前普及率最高的通信工具之一。由于种种原因,用户在使用中常会遇到各种故障,现介绍几种常见故障及其原因。一、灵敏度下降,接收信息不全或收不到信息。在排除BP机正在盲区中的可能后,一般是由于接收板上的晶振质量下降,导致频率偏移所致,也可能是逻辑板故障或电池电压不足所致。 With the rapid development of communication industry, communication tools have been widely popularized. BP has become one of the most widely used communication tools due to its advantages of easy to use and low price. Due to various reasons, users often encounter a variety of faults in use, are introduced to several common faults and their causes. First, the sensitivity decreased, receiving incomplete information or receive no information. After excluding the possibility that the BP machine is in a blind spot, it is generally caused by the decrease of the quality of the crystal on the receiving board, which may result from the frequency offset or the failure of the logic board or the battery voltage is insufficient.
