经常有人反映有线电视收看效果不好,修理人员去查,往往发现并不是线路故障,而是用户接收方法错误所致。 其实接收有线电视并不难,只要掌握三个环节,注意不要走入误区,就可以很好收看。 第一个环节是用户盒。 现在的用户盒上一般有两个插孔,一个标有TV,一个标有FM。TV孔是接收电视节目的,FM孔是接收调频广播的。FM孔的输出只保证调频广播波段(88MHz—108MHz)的幅频特性,因此这个孔一般不能正常接收电视节目。许多用户以为这两个孔没有区别,常常插错,造成收看效果不理想。
Some people often reflect the cable TV reception is not good, the repair staff to check, often found not fault line, but the user received the wrong method. In fact, cable is not difficult to receive, as long as the three aspects of mastery, careful not to go into errors, you can watch well. The first link is the user box. Now the user box generally has two jacks, one labeled TV, one labeled FM. TV hole is to receive television programs, FM hole is to receive FM radio. The output of the FM hole only guarantees the amplitude-frequency characteristics of the FM broadcast band (88MHz-108MHz), so this hole generally can not normally receive TV programs. Many users think there is no difference between the two holes, often inserted wrong, resulting in poor viewing.
