CONSTITUTION:A signal key 7 is installed as one input of a station selection controlling block 2 consisting of a microprocessor. The key 7 is set so that it turns ON when the key 7 is inserted, and it turns OFF when the key 7 is pulled out. If the key 7 is ON, the device 2 can operate all its added functions, and, if the key 7 is OFF, the device 2 regulates its inside to be in the state so that only a stored channel can be selected by using a channel memory function. Therefore, a parent stores only a channel, which seems allowable to be seen for a child, in the device 2 while the key 7 is in ON state as a parental function, and turns OFF the key 7 so that only the stored channel can be selected unless the key 7 is turned ON.，下面是Catv converter专利的具体信息内容。
