電(dian)話(hua)機(ji)常見故障(zhang)有電(dian)源指(zhi)示燈不亮、單(dan)分(fen)機(ji)話(hua)機(ji)提機(ji)無音、分(fen)機(ji)話(hua)機(ji)提機(ji)噪音、分(fen)機(ji)不振(zhen)鈴,可(ke)以先(xian)檢查故障(zhang)原因,然后檢查電(dian)源和線路故障(zhang),如果無法(fa)維修可(ke)以請專業人士上門維修。
電話機原理
電話通信(xin)是通過聲能與電能相互轉換、并利用(yong)“電”這個媒介來傳(chuan)(chuan)輸語言(yan)的一種(zhong)通信(xin)技術。打電話時聲波作(zuo)用(yong)于(yu)送話器上(shang)產生(sheng)電流(liu),電流(liu)沿著(zhu)線路傳(chuan)(chuan)達到對(dui)方電話機,再將(jiang)電流(liu)轉化為聲波就完成了遠程通話。
電話機怎么安裝
首(shou)先要選好分(fen)線(xian)(xian)(xian)(xian)(xian)盒,通常選擇最近的分(fen)線(xian)(xian)(xian)(xian)(xian)盒,然(ran)后(hou)選擇一根配號線(xian)(xian)(xian)(xian)(xian),在分(fen)線(xian)(xian)(xian)(xian)(xian)盒的外(wai)面牽一根線(xian)(xian)(xian)(xian)(xian)到家里面,將線(xian)(xian)(xian)(xian)(xian)接(jie)好電話(hua),撥(bo)111確(que)(que)定端(duan)口(kou)號,確(que)(que)定端(duan)口(kou)號是(shi)否(fou)正確(que)(que),在外(wai)線(xian)(xian)(xian)(xian)(xian)找到一個(ge)(ge)端(duan)口(kou),用專門的跳線(xian)(xian)(xian)(xian)(xian)從內線(xian)(xian)(xian)(xian)(xian)的一個(ge)(ge)端(duan)口(kou)接(jie)到外(wai)線(xian)(xian)(xian)(xian)(xian)那(nei)邊(bian)的端(duan)口(kou)。最后(hou)一步(bu)就(jiu)是(shi)將保險單元插(cha)到外(wai)線(xian)(xian)(xian)(xian)(xian)的端(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。
