Again today for me also. This time I was in Park 1, slightly modified, and after coming out of pin point, it stayed in tones only and no numbers until I switched it completely through all of the modes, swept a tone in every mode, until it got in Gold 1, and then the numbers came back. Everything was normal except no numbers at all on the screen. Its happened a few times as I recall but most of the time it went back to normal operation very quickly, so I really didnt stop and try to figure out what was wrong. Not a big issue to me (unless I have to hunt 'tone only') but it seems like the pin point button circuitry may or may not causing the issue! The CTX may not have a tone but it does give the target icon and shape on the screen.
