changed as shown in Fig.3.
•Setting the wheel circumference
1. How to measure the wheel circumference(Fig.4)
Put a mark on the tire tread and ride the bike one full wheel revolution. Mark the start and
the end of the revolution on the ground and then measure the distance between the two
marks. This is your actual circumference. Or, the "Selecting Values Cross Reference
Table" tells you an approximate circumference according to tire size.
2. Setting the wheel circumference
The figures 2155, standard wheel circumference for 27", will flicker as shown in fig.
3. When using 2155mm without revision, press the Set button. Current Speed and
Elapsed Time will be displayed and 2155mm is set. To revise 2155mm, press the
Start/Stop button to increase the number by one or press the Mode button to de-
crease the number by one. When either button is held down, it will rapidly in-
crease/decrease. Choose a correct circumference between 10mm to 2999mm.
When the desire figure appears, press the Set button. Current Speed and Elapsed
Time will be displayed, then the figure you selected will be set.
3. Resetting or changing the wheel circumference
Set the main unit in the (O) mode with the Mode button, and stop it with the Start/
Stop button. Press the Set button then circumference reset mode will be ready for
operation. Follow instructions given in (2) and revise the circumference as desired.
•Setting the 24-hour clock time
Set the main unit in the
stop it with the Start/Stop button. Press the Set button. The time stored appears, and
the figures for minute flicker. Press the Start/Stop button to advance the figures by
one. When the button is held down, it will rapidly increase. Set a time one or two
minutes ahead of the current time. Press the Mode button. The figures for hour will
flicker. Adjust it by using the Start/Stop button. Press the Set button and the
undisplayed second will return to zero. Setting is completed. *For accurate 24-hour
clock setting, use your radio time signal.(Fig.5)
How to replace the battery (Fig.6)
If the display becomes invisible from the front, it is time for replacing battery. Prepare
a new battery (CR2032) in advance, before taking out the old battery. Insert a new
battery so that it is tightly fitted to the contact, as shown in the figure. When replac-
ing, be careful not to press the buttons. Replacement must be done promptly (within
20 seconds).
After replacement, don´t press AC button, because the data including total distance
(odometer) is continuously measured.
However, the following malfunction might occur after replacement:
•No display appears.
•Unusual display appears.
•Display is O.K. but button don´t work.
In the above cases, press AC button so that display / buttons returns to normal. (If
AC button is pressed, all the data including odomater is erased. Please refer to
