对讲机出现实际通信距离缩短的现象时常发生。出现这种现象,除一部分是由于机内元器件损坏外,有很大一部分是由于操作使用不当引起的。下面笔者就造成这种现象的机外常见故障进行浅析。一、功率设置不当一般对讲机为了节省能源、减少干扰都设置有高(H)、低(L)或高(H)、中(M)、低(L)功率输出档,所以在远距离通信时,最好检查一下功率档是否选择得当。因为 Walkie-talkies occur shortening the actual communication distance of the phenomenon often occurs. This phenomenon occurs, in addition to a part of the internal components due to damage, a large part due to improper operation caused. The following author of this phenomenon caused by the machine outside the common fault analysis. First, improper power setting General walkie-talkie in order to save energy, reduce interference are set with high (H), low (L) or high (H), in (M), low (L) power output file, so in long-distance communication , It is best to check whether the power file is properly selected. because
