Before you start cycling, check that no wires affect your
safety when cycling and that your handlebars turn normally, brakes
and gears function properly etc. Also, carefully ensure that all
sensors are installed securely and no surplus wires are hanging
loosely.
Check that you have set the correct cycling settings in your
wristwatch receiver.
The sensors contain strong magnets, which may damage
diskettes, magnetic cards such as credit cards, or other
electromagnetic equipment.
