System Is Only Partially Working
It is important to check and make sure that the whole of your system is working properly. Sometimes, only part of the system is damaged in a flood or storm, so while some of your sub-stations may be communicating with the master station, not all of the sub-stations might be working.Go through every sub-station and make sure that it can communicate clearly with the master station. Any interference, static, or choppiness is a sign that it needs to be repaired.
If you have a video intercom system, the audio might still work, while the video part might not be working anymore. If this is your situation, you again need to check all of the stations, to make sure the audio is still working and note one which ones the video is not working. While you can limp along without video, if you still have audio, it’s a much better idea to get your video intercom system repaired before further damage occurs.
