Welcome to Radio Reference.
Just an FYI..... when you are asking for technical help, it's essential to provide very specific symptoms, information, and any error messages that appear should be quoted exactly. Also, what version of Windows are you using? The more specific info that you provide, the more accurate and helpful the answers will be.
In this quote, what exactly is being asked for? What is the exact error message you are seeing?
Went back to the manual, installed the Sentinal software but it kept telling us to load a version that was long surpassed.
Just making a guess here, but if you are being asked for a version of .NET framework.....
You didn't say which version of Windows you are using, but if it's Windows 10, go to:
Control Panel --> Programs and features --> Turn Windows features on or off (in the upper left corner)
once that window populates, click in the box that says ".NET Framework 3.5 (Includes .NET 2.0 and 3.0)”. You don't need to select the 2 sub-headings under that main one.
Click OK, and it will be installed. After this, you should be able to install Sentinel. Be
certain you are installing the latest version of Sentinel for the BCD536HP (V 2.02.01)
If that message is asking you for a different version of the Sentinel software, the latest version is availably here:
info.uniden.com
can see the surrounding agency ID's on the screen, but there is no sound coming from the unit
You haven't listed your location info in your user profile, so it would be a good idea to tell us what specific agencies you are trying to monitor. State, County, City or Town, and exactly which agency (fire, police, etc.)
Preferably, locate those agencies you are trying to monitor in the RR database at this link, and post a direct link to them from that database. That way we can see exactly what you are referring to:
