If you have the scanner set for the ID Search Mode, it will find all the Talkgroups but will just show the TG number, with no name tag identifier. You can set this name tag to display the name for each talkgroup instead of the number. These name identifiers can be found on the IIMARS frequency page at the bottom for Bingham County.
Are you manually programming the scanner or using software? I find programing the 996 to be much easier if software is used, in fact I have been using software for so long, I'm not sure I remember how to do it without it.
I use Proscan which has a free 30 day trial period.

There is also Freescan which is a free program.

There is a lot of good information here.

There can be a fairly big learning curve for using this scanner. I have an IIMARS software file in Proscan which I could send to you if you have the Proscan sofware on a computer. I don't know which firmware version is on your 996, but the firmware might have to be upgraded at some point also.
Send me a private message if you want the software file sent.
