電話機故障維修

電(dian)(dian)話(hua)機常見故障有電(dian)(dian)源指示燈不亮、單分(fen)機話(hua)機提(ti)機無(wu)音、分(fen)機話(hua)機提(ti)機噪音、分(fen)機不振鈴，可以先檢(jian)查故障原(yuan)因，然后檢(jian)查電(dian)(dian)源和線(xian)路故障，如果無(wu)法維(wei)修(xiu)可以請專業人士上門(men)維(wei)修(xiu)。

電話機原理

電(dian)話(hua)(hua)通(tong)(tong)信是通(tong)(tong)過聲能與電(dian)能相互轉換、并利(li)用“電(dian)”這個(ge)媒介來(lai)傳(chuan)輸語(yu)言(yan)的(de)一種通(tong)(tong)信技術。打電(dian)話(hua)(hua)時聲波(bo)作用于送話(hua)(hua)器上產生(sheng)電(dian)流(liu)，電(dian)流(liu)沿著(zhu)線路傳(chuan)達到對方電(dian)話(hua)(hua)機，再將(jiang)電(dian)流(liu)轉化為聲波(bo)就完(wan)成了遠(yuan)程通(tong)(tong)話(hua)(hua)。

電話機怎么安裝

首先要選(xuan)(xuan)好(hao)分(fen)線(xian)(xian)(xian)(xian)盒，通常選(xuan)(xuan)擇(ze)最近的(de)(de)分(fen)線(xian)(xian)(xian)(xian)盒，然(ran)后選(xuan)(xuan)擇(ze)一根(gen)配號線(xian)(xian)(xian)(xian)，在分(fen)線(xian)(xian)(xian)(xian)盒的(de)(de)外(wai)(wai)面(mian)牽一根(gen)線(xian)(xian)(xian)(xian)到(dao)家里(li)面(mian)，將線(xian)(xian)(xian)(xian)接好(hao)電(dian)話，撥111確(que)定(ding)端(duan)口(kou)號，確(que)定(ding)端(duan)口(kou)號是否正確(que)，在外(wai)(wai)線(xian)(xian)(xian)(xian)找到(dao)一個端(duan)口(kou)，用(yong)專門的(de)(de)跳(tiao)線(xian)(xian)(xian)(xian)從(cong)內(nei)線(xian)(xian)(xian)(xian)的(de)(de)一個端(duan)口(kou)接到(dao)外(wai)(wai)線(xian)(xian)(xian)(xian)那邊的(de)(de)端(duan)口(kou)。最后一步就是將保險單元插到(dao)外(wai)(wai)線(xian)(xian)(xian)(xian)的(de)(de)端(duan)口(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。
