Replacing the battery
Computer
If turns on, replace the battery. Install a new lithium battery
(CR2032) with the (+) side facing upward. After the battery change,
go through the restart operation, by pressing the AC button.
Then restart the computer according to “How to restart”.

Sensor
Replace the battery when the Speed digit flashes while riding.
After replacement, check the positions of the sensor and magnet.
After the battery is replaced, ID setting is required again. For
*
details, refer to “Sensor ID setting” on the menu screen.
Troubleshooting
MODE does not work when the computer is mounted on its bracket.
Check that there is no dirt between the bracket and the computer.
Wash off the bracket with water to get rid of any dirt.
The sensor signal reception icon does not flash (the speed is not displayed). (Move the com-
puter near the sensor, and turn the front wheel. If the sensor signal reception icon flashes, this
trouble may be a matter of transmission distance due to battery drain, but not any malfunction.)
Set the sensor ID.
Set the ID according to “Sensor ID setting” on the menu screen.
Check that the clearance between the sensor and magnet is not too large. (Clearance: within 5 mm)
Check that the magnet passes through the sensor zone correctly.
Adjust the positions of the magnet and sensor.
Check that the distance between the computer and sensor is correct. (Distance: within 20 to 70 cm)
Install the sensor within the specified range.
Is the computer or sensor battery weak? In winter, battery performance diminishes.
Replace with new batteries. After replacement, follow the procedure “Replacing the battery”.
Incorrect data of the sea level altitude.
Is the sea level altitude corrected?
The sea level altitude may vary due to changes in atmospheric pressure. Correct the sea level altitude ac-
cording to “Sea level altitude correction” on the menu screen.
No display.
Is battery in the computer run down?
Replace it. Then restart the computer referring to “How to restart”.
Incorrect data appear.
