Getting back into riding again and my MTB has an AC3 computer on it. Used it for years, but now cant for the life of me remember how to reset daily totals. I replaced the battery in it and have since figured out how to reset Km/Mph, but now after a few rides my miles keep adding on top of each other. This of course throws off my averages and everything else for ever ride.

Does anybody know how to reset this? I have been trying all types of button combos with no luck. Should I just give up and get something newer?

I have an app to run on my phone that gives me all the GPS data, but it's usually just in my pack, not mounted to my bars. I like to see my stats as I ride.
