towermaintenance 0 Posted August 29, 2012 Good afternoon, One of our residence has a Siedle installed in her place. I see DAC 610-0 with La & Lb hooked up a live phone line and 1 & 7.1 hooked up to other Siedle modules. Her 2nd line stopped working; thus her Siedle system. I replaced the 2nd phone line with the 1st phone line. Using my butt set, I hear a dial tone at the La & Lb. My question is when we press the front button of the Siedle, there is no notification tone like before. Her phone system is Panasonic kx-taw848. On the transformer module, I noticed there is NO red light. I am decent with meters, troubleshooting... How would I find out whether it is the Siedle dialing or not dialing or the phone system not ringing... Thanks so much Share this post Link to post Share on other sites
