How to restart
After changing the battery, or when the computer displays an error, restart the computer
according to the following procedure.
With the restarting operation, the speed unit, date, tire size, and record data in the data view are retained.*
When the restarting operation is performed before 0:00 in the morning, the trip distance and the Car-*
bon offset for the day are not saved due to the data view’s update timing. To retain the measurement
data for the day, perform the restarting operation before starting measurement on the next day.
Refer to “Data view’s update timing” for the procedure to save the data view.
Press the 1. AC button on the back of the computer.
Set the date. To set the date, refer to “Preparing the computer-3”.2.
At the time of setting the date, the latest record date in the data view is initially displayed, and any *
date before that cannot be set.
Set the clock. Refer to “Preparing the computer 4”.3.
Maintenance
To clean the computer or accessories, use diluted neutral detergent on a soft cloth, and
wipe it off with a dry cloth.
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

When the speed is not displayed even after adjusting cor-
rectly, replace the battery. Install a new lithium battery
(CR2032) with the (+) side facing upward. After replacement,
check the positions of the sensor and magnet.
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.)
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.
Is the computer installed at the correct angle?
Back of computer must face toward the 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”.
No display.
Is battery in the computer run down?
Replace it. Then restart the computer referring to “How to restart”.
Incorrect data appear.
Restart the computer referring to “How to restart”.
