固定電話機按鍵被鎖怎么辦

電(dian)話被鎖了(le)，通(tong)常有2情況：

一是有(you)的(de)帶鎖電話機(ji)，機(ji)殼后面(mian)有(you)個機(ji)械鎖，可使(shi)鍵盤鎖全(quan)鎖、全(quan)開(kai)。這種(zhong)情況用鑰匙(chi)(chi)打開(kai)即可。如已找不(bu)到鑰匙(chi)(chi)，可將內部接線2根之間聯(lian)通，以(yi)能撥號為原則。

二是撥號電路(lu)(lu)故障。包括(kuo)撥號集成(cheng)電路(lu)(lu)損壞和撥號音(yin)頻輸出電路(lu)(lu)故障。后者多數情況下是三(san)極管(guan)的問題

固話按鍵數字旁英文字母有什么用處

在許多(duo)電話機上(shang)(shang)的按鍵(jian)上(shang)(shang)，除了(le)“O”、“1”、“*”、“#”上(shang)(shang)沒有字(zi)母(mu)外，其它按鍵(jian)上(shang)(shang)都有三(san)個(ge)字(zi)母(mu)，而這些字(zi)母(mu)中沒有“Q”或“Z”這兩個(ge)字(zi)母(mu)。這是為什么(me)呢？

這(zhe)(zhe)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)歷史(shi)留下的(de)(de)(de)痕跡。在(zai)(zai)(zai)(zai)按鍵式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)之前(qian)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)是轉(zhuan)盤式的(de)(de)(de)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)轉(zhuan)盤上有(you)10個圓洞，分(fen)別代表0-9。為(wei)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)號(hao)碼(ma)便于(yu)記憶，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)公司為(wei)每(mei)個數(shu)字(zi)分(fen)配了字(zi)母(mu)(mu)，于(yu)是人(ren)們可以把一個人(ren)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)改用(yong)自己習慣(guan)的(de)(de)(de)字(zi)母(mu)(mu)來(lai)記憶，比如“Char leston”的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)號(hao)碼(ma)的(de)(de)(de)前(qian)兩(liang)個數(shu)字(zi)號(hao)碼(ma)是“2-4”的(de)(de)(de)話(hua)(hua)(hua)(hua)(hua)，就可以記作“C-H”。 在(zai)(zai)(zai)(zai)10個圓洞中，“0”通常專門用(yong)來(lai)撥(bo)向話(hua)(hua)(hua)(hua)(hua)務員，“1”則通常是撥(bo)向國(guo)際(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)公司的(de)(de)(de)信號(hao)，這(zhe)(zhe)樣(yang)只(zhi)剩(sheng)下8個數(shu)字(zi)需(xu)要指定字(zi)母(mu)(mu)了。每(mei)個數(shu)字(zi)分(fen)配3個，這(zhe)(zhe)只(zhi)用(yong)掉(diao)了字(zi)母(mu)(mu)表上的(de)(de)(de)24個字(zi)母(mu)(mu)，于(yu)是就沒有(you)使(shi)用(yong)最不常用(yong)的(de)(de)(de)“Q”或“Z”。現在(zai)(zai)(zai)(zai)雖(sui)然(ran)(ran)轉(zhuan)盤式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)已(yi)退出歷史(shi)舞臺(tai)，許多按鍵式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)卻保留了在(zai)(zai)(zai)(zai)每(mei)個數(shu)字(zi)鍵上各放三個字(zi)母(mu)(mu)的(de)(de)(de)習慣(guan)。當然(ran)(ran)這(zhe)(zhe)并(bing)非永遠不變，現在(zai)(zai)(zai)(zai)有(you)不少電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)(hua)(hua)(hua)(hua)機(ji)，就將“Q”放在(zai)(zai)(zai)(zai)“7”鍵上，“Z”放在(zai)(zai)(zai)(zai)“9”鍵上，使(shi)這(zhe)(zhe)兩(liang)個數(shu)字(zi)鍵上各有(you)了4個字(zi)母(mu)(mu)。

固定電話使用小技巧

1、按錯數字后如何刪除撥錯的這一位數字

相信很多人在使用固定的電話(hua)的時(shi)候會遇到一(yi)(yi)個問題：撥(bo)打一(yi)(yi)個很長的號碼時(shi)，號碼撥(bo)到一(yi)(yi)半(ban)的時(shi)候突然按(an)錯(cuo)一(yi)(yi)位鍵，這時(shi)只能放下(xia)話(hua)筒，從頭開始再拔一(yi)(yi)遍，而且往往心情急躁時(shi)，后面又容(rong)易再撥(bo)錯(cuo)。

經驗：其實正確的拔號方式(shi)應該是：在(zai)預撥號狀態（即不拿起話(hua)筒(tong)，直(zhi)接(jie)按數(shu)字(zi)鍵），當輸入錯誤(wu)是可以按“刪除/R”,就可以(yi)有逐位刪除(chu)號碼了，輸入(ru)完成后按(an)“重撥/回撥”鍵一次即可(ke)自(zi)動(dong)啟動(dong)免(mian)提將號碼撥出。

2、來電的回撥

有時來電未接到，需要重撥(bo)回去(qu)，如果記(ji)在紙上再(zai)撥(bo)回去(qu)會很麻煩并且(qie)浪費(fei)時間。

經(jing)驗：（有來(lai)電(dian)顯(xian)示的電(dian)話），按一下“”查尋到要回撥的號碼，按一下“重撥/回(hui)撥”鍵可將來電號(hao)碼撥出，如按住“重撥/回(hui)撥”鍵2秒，會(hui)在來電(dian)號碼前加“0”后再撥出。
