一个办公室里多人共用一邮电话,常常让靠近电话的人不能安心工作,手头的事情不断被电话铃声打断。如果在电话机上附带一个信号灯装置,它可以竖立在电话机上,或者用导线引出挂在墙上,就可以避免这一问题。外人给办公室打电话时,多按一个数字键,相应的指示灯就会随铃声一起闪烁,对应于这个灯的人就去按电话。例如,该办公室老张的代号为6,老张家人给他打电话时多按一下“6”字键,则办公室内的铃声响起的同时,6号灯同时闪烁,于是老张就去接电话,用不着麻烦别人传呼。 In an office where people share a postal phone, people who are close to the phone often do not feel comfortable working and are constantly being interrupted by phone ring tones. This can be avoided if a signal light unit is attached to the telephone, which can be erected on the telephone or led out to the wall. When an outsider makes a phone call to the office, he or she presses a number key more frequently, the corresponding indicator light flashes with the ringtone, and the person corresponding to the light goes to the phone. For example, the name of Chang's office in the office is 6, when the old Zhang family called him more and press the “6” key, the 6th lamp blinks at the same time as the ring in the office rings, so Zhang goes Answer the phone, do not bother others paging.
