To attach the equipment:
1. Attach the bike mount to the right or left handlebar using
rubber grip, nut and bolt provided. Tighten until the bike
mount is fixed into place, using the rubber grip for a firmer
contact.
2. Attach the cadence sensor to a stationary point just behind
the pedal, using the rubber grip for a firmer contact. There
should be maximum 100cm (39 inches) between the sensor
and the bike mount, and less than 30 degrees vertical angle.
3. Attach the cadence magnet to a pedal so that it is directly
aligned with the sensor with less than 5mm (0.2 inches)
between.
4. Attach the speed sensor to either leg of the front forks, using
the rubber grip for a firmer contact. There should be
maximum 100cm (39 inches) between the sensor and the
bike mount, and less than 30 degrees vertical angle.
5. Attach the speed magnet on a spoke of the front wheel so that
it less than 5mm (0.2 inches) from the sensor.
6. Check and adjust as necessary, then snip the ends off the
clips so that no excess remains.
7. Fit the watch into the bike mount.
8. Press MODE on the watch to switch to BIKE Mode.
9. Press ST/SP/- to activate signal reception. The display
shows “- -“, then changes to 0 once a successful signal is
received.
10. Ride the bike a short distance to make sure signals are
being sent to the watch successfully.
11. You are now ready to begin your trip.
The watch can work with one or both sensors.
When the display shows a low battery icon
(see
‘Battery’ section) replace the battery for the corresponding unit.
STEP 2: ENTER WHEEL CIRCUMFERENCE
You must set the bike’s wheel circumfer-
ence on the watch so it can accurately
calculate your speed and distance. If you
do not know the bike’s wheel circumfer-
ence, you can check the manufacturer’s
specifications or measure it by marking
the wheel where it touches the ground,
and then rotating the wheel once fully along the ground.
Measure the difference between the two marks.
Most wheels have their specifications written on them.
To specify this information on the watch:
1. Press MODE to switch to the BIKE Mode.
2. Press and hold FUNC/SET for 2 seconds.
3. Press SELECT/+ or ST/SP/- to change the circumference
(cm or inches, depending on the measurement unit you
selected in CLOCK Mode).
4. Press FUNC/SET to save your changes.
You can also use the PC software for this operation (see
PC section).
