Wireless Sensor

In order to prevent any interference with the sensor signal, the transmission range is designed to be 20 to 100 cm, in addition to use of the ID code� (This receiving range is only a reference�) Please note the following points�

•To use this unit, the sensor ID has to be set�

•Two different IDs, ID1 and ID2, can be registered to this unit, which are identified automatically�

•The computer cannot receive the signal when the distance between the sensor and computer is too long� Temperature drop and battery drain may worsen the receiving sensitivity even if they are within the trans- mission range�

A

Install the sensor and magnet

The distance between the computer and sensor is within the transmis- sion range, and the mark on the sensor points to the computer�

BThe magnet faces the sensor zone of the sensor�

CThe clearance between the sensor face and mag- net is less than 5 mm for Speed and 3 mm for Cadence, respectively�

Measure wheel circumference (L) of your bike	L mm
To get the most accurate calibration do a wheel roll out. With the valve stem perpendicular 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.
