I’m having a problem getting my HP-1 working properly on one of the systems I monitor. When I have the system locked I can see the signal strength meter move but no sound. I’m thinking I might have changed a setting in Sentinel when I did my last DB update. When I check the site info there are 3 sites 2 that I listen to. The one I do not listen to is in red the other 2 are not. The site is the Ohio Marcs-IP site. Any ideas?
