You probably already know, and it can take some time and patience, but the 996 has a fire tone out search function to decode the tones for you if no one has a list available.
If you can receive them, and they have a daily test page, record a video of your scanner during the test page with your cell phone, email that video to yourself so you can open it on your computer. Go to your phones app store and download a guitar tuning app that shows the guitar pitch in HZ, use the first tuning app, play the video on your computer, write down the tones the guitar tuning app shows you. Tada... you have the tones.
you can download this free program to your computer and hook your scanner to your computer and it will decode the tone show you the tone freq Tone decoder
if anybody download this file you need to change the config file and change the email address on it and add your own tones as i upload the wrong file instead of the twotone finder
