對講機進水后，一定不能上電開機！先拆開機器外殼，小心取出機板，用專用洗板水將線路板仔細清洗干凈、晾干，用細小毛刷清理干凈電路板上的污漬；有條件可用超聲波清洗機進行清洗；其次撈出后用電吹風吹干（注意溫度不可過高），清理干凈水份后，通過儀器檢測各項指標是否正常，如有其它故障再按常規方法進行檢修。沈陽對講機哪家好你知道嗎？

沈陽對講機(ji)從(cong)軟件方(fang)面去排除，是否為參數設置問題。解決(jue)方(fang)法：把(ba)相(xiang)同型號、頻段的機(ji)器(qi)讀出參數，然后直(zhi)接寫入(ru)到(dao)故障機(ji)，看能否解決(jue)。

機器(qi)硬件(jian)問題(ti)：拆機后用萬用表測(ce)TP點(dian)（即(ji)VCO電(dian)(dian)壓(ya)測(ce)試(shi)點(dian)）無(wu)鎖定電(dian)(dian)壓(ya)，試(shi)調C180，該點(dian)電(dian)(dian)壓(ya)無(wu)變(bian)化，再測(ce)震蕩管Ｑ14各極都無(wu)電(dian)(dian)壓(ya)， 據此(ci)可知Ｑ14沒有(you)振蕩。懷疑是電(dian)(dian)源電(dian)(dian)路有(you)問題(ti)，檢測(ce)為(wei)鎖相環路提供電(dian)(dian)源的Q32無(wu)5V電(dian)(dian)壓(ya)輸出，更(geng)換Q32故(gu)障(zhang)排除。

對電路(lu)腐蝕嚴重的(de)進(jin)(jin)水機(ji)一(yi)般(ban)都(dou)無法修復，因此機(ji)器進(jin)(jin)水后(hou)應進(jin)(jin)行及時處置，不然，就會腐蝕機(ji)板造成無法修復。

沈陽對(dui)講機(ji)可充(chong)電(dian)(dian)(dian)鋰離子(zi)電(dian)(dian)(dian)池已(yi)在(zai)(zai)對(dui)講機(ji)中廣泛，在(zai)(zai)使用中不可過充(chong)、過放(會損(sun)壞(huai)電(dian)(dian)(dian)池或使之報(bao)廢)。因此，在(zai)(zai)電(dian)(dian)(dian)池上有保護(hu)元器件或保護(hu)電(dian)(dian)(dian)路(lu)以(yi)(yi)防止昂(ang)貴(gui)的電(dian)(dian)(dian)池損(sun)壞(huai)。（冒(mao)牌劣質(zhi)產品多數(shu)沒(mei)有該(gai)保護(hu)電(dian)(dian)(dian)路(lu)） 鋰離子(zi)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)要求很高，要保證終止電(dian)(dian)(dian)壓精度在(zai)(zai)1%之內，目前各(ge)大半導體器件廠開(kai)發出(chu)多種鋰離子(zi)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)的ic，以(yi)(yi)保證可靠、快速(su)地(di)充(chong)電(dian)(dian)(dian)。

鋰(li)離(li)子電(dian)(dian)池(chi)不適(shi)合(he)用作大電(dian)(dian)流(liu)放(fang)電(dian)(dian)，過大電(dian)(dian)流(liu)放(fang)電(dian)(dian)時會降低放(fang)電(dian)(dian)時間(jian)(內部會產生較高(gao)的溫(wen)度(du)(du)(du)而損耗(hao)能量)。因此電(dian)(dian)池(chi)生產工廠給出大放(fang)電(dian)(dian)電(dian)(dian)流(liu)，在使用中應小于大放(fang)電(dian)(dian)電(dian)(dian)流(liu)。 鋰(li)離(li)子電(dian)(dian)池(chi)對溫(wen)度(du)(du)(du)有一定要(yao)求，工廠給出了充電(dian)(dian)溫(wen)度(du)(du)(du)范圍(wei)、放(fang)電(dian)(dian)溫(wen)度(du)(du)(du)范圍(wei)及保存溫(wen)度(du)(du)(du)范圍(wei)。
