防爆對講機天線使用
1.只能使用原配(pei)或認可(ke)的天(tian)線(xian)。未經(jing)認可(ke)的天(tian)線(xian),經(jing)改裝或增添了附(fu)件的天(tian)線(xian)可(ke)能會損壞對講機(ji)或違反信息產業部無線(xian)電管理局的規定。
2.在使(shi)用時,不要用手去拿天線。
3.防爆對講機天線不能擰下,否則(ze)在發(fa)射時(shi)容易把功率管燒壞。
4.不要使(shi)用(yong)損壞的(de)天(tian)線(xian)。在發射時,如果損壞的(de)天(tian)線(xian)接觸(chu)皮膚(fu),可能(neng)引起請輕微的(de)灼傷(shang)。
防爆對講機的常見故障與維修
天(tian)(tian)(tian)線(xian):天(tian)(tian)(tian)線(xian)是(shi)(shi)整(zheng)機(ji)收(shou)發關鍵部件,天(tian)(tian)(tian)線(xian)一旦失效或不良,必影響(xiang)收(shou)發通信效果。用戶在(zai)(zai)使用中經(jing)常會用手拿天(tian)(tian)(tian)線(xian)來帶動(dong)整(zheng)臺對(dui)講(jiang)機(ji),更(geng)嚴重(zhong)的是(shi)(shi)在(zai)(zai)天(tian)(tian)(tian)線(xian)尾巴甩動(dong)對(dui)講(jiang)機(ji)。由于天(tian)(tian)(tian)線(xian)口(kou)是(shi)(shi)整(zheng)機(ji)高(gao)頻(pin)接(jie)收(shou)發射的出入口(kou),經(jing)常使用的是(shi)(shi)專(zhuan)業TNC、BNC、SMA 等接(jie)口(kou),此(ci)時由于天(tian)(tian)(tian)線(xian)本身機(ji)械強度(du)的原因,久(jiu)而久(jiu)之產生天(tian)(tian)(tian)線(xian)外皮脫(tuo)落,天(tian)(tian)(tian)線(xian)針斷裂,或天(tian)(tian)(tian)線(xian)針接(jie)觸面變(bian)小,嚴重(zhong)時會使天(tian)(tian)(tian)線(xian)針與電路(lu)板之間的聯接(jie)處產生脫(tuo)焊。
電(dian)(dian)池:電(dian)(dian)池是供給整機(ji)能量的(de)來源。由于對(dui)講機(ji)發射時(shi)電(dian)(dian)流較(jiao)大(da),一(yi)(yi)次(ci)性堿性電(dian)(dian)池用(yong)(yong)的(de)比較(jiao)少(shao)。大(da)部分(fen)對(dui)講機(ji)采(cai)用(yong)(yong)的(de)是可反復(fu)充(chong)電(dian)(dian)的(de)鎳鎘(ge),鎳氫(qing),或鋰離子(zi)電(dian)(dian)池。經(jing)常會有用(yong)(yong)戶提出電(dian)(dian)池使用(yong)(yong)時(shi)間不夠長,剛充(chong)完電(dian)(dian)沒(mei)按幾下就沒(mei)電(dian)(dian)了(le),除(chu)了(le)個別(bie)經(jing)營商(shang)采(cai)用(yong)(yong)劣(lie)質電(dian)(dian)芯,影響正常使用(yong)(yong)外,正確的(de)使用(yong)(yong)方法(fa)是能夠延(yan)長電(dian)(dian)池的(de)使用(yong)(yong)時(shi)間及(ji)使用(yong)(yong)壽(shou)命的(de)。調查和詢問用(yong)(yong)戶發現,一(yi)(yi)部分(fen)用(yong)(yong)戶會在要使用(yong)(yong)時(shi)放在充(chong)電(dian)(dian)器里(li)隨便充(chong)一(yi)(yi)段時(shi)間,拿起來就用(yong)(yong),沒(mei)有規律的(de)充(chong)放電(dian)(dian)。
