If your fire department is being toned out is there a way that the 396 will search for and find the tone-out frequency like it does CTCSS codes?

Not tell the 396XT comes out.
Not with existing radios directly.
The way I do it is pretty simple, I record the fire channels with ScannerRecorder (free, download) and then run the resultant .wav files thru Adobe Audition. Audition displays the file visually and it is real simple to figure out what are the tones and what is voice by looking at the wave form. Just click into the waveform and the actual frequency of the tone is displayed.
A local fire channel here my have a couple dozen calls during the day, it takes 15 -20 minutes to run thru a days worth of recording this way and jot down the tones in use. Pretty soon you can recognize the tone sets visually. I can even tell what dispatch center is toning out by the visual representation of the tonesets, they each have a distinct pattern pre and post tone.
CommTek also has a decoding application, I bought it but it wasn't as easy to use as my method.
