I'm just experimenting with my FR970, and it seems there's no way for it to auto-lock the buttons - that is, I have to always lock it manually.
I found no setting to auto-lock the buttons (the FR965 had this setting).
Why would they remove this setting? When I start my watch, I don't want it to react to screen or button activity; this seems like a normal usage pattern. Any idea why they would remove this feature?
