電話機故障維修
電(dian)話(hua)機常(chang)見(jian)故(gu)障(zhang)(zhang)有電(dian)源指示燈不亮、單分(fen)機話(hua)機提機無音(yin)、分(fen)機話(hua)機提機噪音(yin)、分(fen)機不振(zhen)鈴，可以(yi)(yi)先檢(jian)查(cha)故(gu)障(zhang)(zhang)原因，然后檢(jian)查(cha)電(dian)源和線路故(gu)障(zhang)(zhang)，如果無法維修(xiu)可以(yi)(yi)請專(zhuan)業(ye)人士上門維修(xiu)。
電話機原理
電(dian)(dian)話(hua)通(tong)信(xin)是(shi)通(tong)過聲(sheng)能與電(dian)(dian)能相互轉換、并利用(yong)“電(dian)(dian)”這個媒(mei)介來傳輸語言的一(yi)種通(tong)信(xin)技術(shu)。打電(dian)(dian)話(hua)時聲(sheng)波(bo)作用(yong)于送(song)話(hua)器上產生電(dian)(dian)流，電(dian)(dian)流沿著線(xian)路傳達到(dao)對方電(dian)(dian)話(hua)機，再將(jiang)電(dian)(dian)流轉化(hua)為聲(sheng)波(bo)就完(wan)成了遠程通(tong)話(hua)。
電話機怎么安裝
首(shou)先(xian)要(yao)選(xuan)(xuan)好(hao)分(fen)線(xian)(xian)(xian)(xian)(xian)(xian)盒，通常選(xuan)(xuan)擇(ze)最近(jin)的(de)分(fen)線(xian)(xian)(xian)(xian)(xian)(xian)盒，然(ran)后(hou)選(xuan)(xuan)擇(ze)一根配號線(xian)(xian)(xian)(xian)(xian)(xian)，在分(fen)線(xian)(xian)(xian)(xian)(xian)(xian)盒的(de)外(wai)面(mian)牽一根線(xian)(xian)(xian)(xian)(xian)(xian)到(dao)(dao)家(jia)里面(mian)，將線(xian)(xian)(xian)(xian)(xian)(xian)接好(hao)電話，撥111確定(ding)端(duan)(duan)口(kou)(kou)號，確定(ding)端(duan)(duan)口(kou)(kou)號是(shi)否正(zheng)確，在外(wai)線(xian)(xian)(xian)(xian)(xian)(xian)找(zhao)到(dao)(dao)一個端(duan)(duan)口(kou)(kou)，用專(zhuan)門的(de)跳(tiao)線(xian)(xian)(xian)(xian)(xian)(xian)從內線(xian)(xian)(xian)(xian)(xian)(xian)的(de)一個端(duan)(duan)口(kou)(kou)接到(dao)(dao)外(wai)線(xian)(xian)(xian)(xian)(xian)(xian)那(nei)邊的(de)端(duan)(duan)口(kou)(kou)。最后(hou)一步就是(shi)將保險單元(yuan)插(cha)到(dao)(dao)外(wai)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)端(duan)(duan)口(kou)(kou)。
如何選購電話機
首先要選用與當地交換機制式相適應的電話機，然后要考慮電話機的功能，比如免提揚聲、液晶顯示、錄音應答等功能；購買前還要檢查電話機的外觀質量是否合格，聲音是否清晰無噪聲，聲調是否正常等。建議選擇正規品牌電話機，質量有保障。
