Red Light Inside Is Off and No Caller ID
Hi, usually this red light is a "new message" indicator when it's on, the normal condition should be off. If the caller ID function is not working could be cables misconnected, the connector labeled as line should be connected to wall line outlet, the connector labeled as phone should be connected to your telephone. In the worst of cases if the connections are OK, there's a problem with the line or the caller ID unit.
