笔者几年前购买了一部丰达牌HW829P/TSD(LCD)C型无绳电话机,子机和母机均带有液晶显示屏,母机除具备普通电话机所有功能外,还附带100年的电脑万年历,可显示年、月、日、星期、时钟;该机还能自动监测显示室内温度;设定两次闹铃;子机配有独立的充电座,并具有夜光功能;子母机之间通话时,能从设置的10个信道中自动选择空闲信道,当然也可手动选择,以防与其它无绳电话窜机;设有6.5万组随机安全密码防止被别人盗打,通话距离达500m,一旦子机超出使用范围母机将自动挂机。特别是该机采用四节5号镍镉充电电池做后备电源,即使市电停电,子机也可照常使用,待机时间约30小时,不过此时子母机内部呼叫对讲功能暂时失效。总之该机使用方便,效果不错。但实际使用过程中发现,后备的镍镉充电电池如果充电不及时,停电后使用至电量耗尽,主机屏显就会消失,市电恢复后也不能立即使用,需将电池取出重新充电,并且需对
