Query: Cannot be zero'd

This arrived today and I quickly discovered its obvious design flaw. All well and good that it will calculate your distance etc over a 7 day period but its laughable that the read-out cannot be completely zero'd unless you do a complete system reset resulting in having to input the time and all your personal information again. The lack of this flexibility is a very short-sighted decision by the manufacturer.
