I've had my HX400V for a few days now and so far I am very impressed. However, I can't get to grips when changing the settings for the memory locations MR1 and MR2. The help guide under 'To change registered settings', says "Change the setting to the desired one and re-register the setting to the same mode number.", but doesn't explain exectly how to re-register the setting. I've had some success, but not sure how I manged it. I would be grateful for any help.
