Measure wheel circumference (L) of your bike
To get the most accurate
calibration do a wheel roll out.
With the valve stem perpen-
dicular to the ground, mark
the pavement at the valve
stem. With the riders weight
on the bike, roll the wheel one tire revolution
in a straight line and mark the ground when
the valve stem is perpendicular to the ground
again. Measure the distance in millimeters. This
is the most accurate wheel calibration number.
Before using the computer, please thoroughly read this manual and keep it for future
reference.
Our website shows how to install and set up the unit on your bicycle, in an understandable way
using a movie (http://www.cateye.com).

The clearance between the speed sensor •
and magnet is 5 mm or less.
After installing the speed sensor, check that the speed is displayed on the computer by turn-
ing the front wheel with the computer installed to the bracket. If not displayed, review the
installation conditions, and check the positions of the speed sensor and magnet.
CAUTION:
The computer in the bike mode measures speed only when installed on the bracket.
NO!
This unit can be used for measuring speed and distance while installed on your bicycle, and also used
as a pedometer for measuring calorie consumption and number of steps in everyday life while carried
with you all the time. First of all, go through “Preparing the computer” and “How to install the unit on
your bicycle”.

How to measure the stride
The stride means the distance between
adjacent tiptoes of your footprint. Mark at
your tiptoe in the start point and the point
after you make 10 steps, and then measure
the distance between them.
The stride becomes larger as you walk faster. *
For measurement, walk at a normal speed.
An average stride is determined by dividing the
walking distance by 10 (number of steps).
Walking distance
