Setting(s) of wheel size(s) (wheel
circumference)
Under "Wheel Size 1" or "Wheel
Size 2", you should now enter the
wheel circumference of your bike.
This can be seen from the wheel
size data shown on the side of your
tyre. Please consult the table shown
on P. 45 for the appropriate 4-digit
number.
Next press the MODE button until
such time as the appropriate digit
appears, then use the SET button
to move to the next digit. Once you
have confirmed the final digit, you
automatically re-access the "Set
Wheel" window. Should you wish
to make settings for a second bike,
press the SET button, otherwise
move to the "Clock" window by
pressing the MODE button.
