1. How to Put in a Battery
1.Remove the battery cover on the back with a coin or a similar opener (Fig. 1).
2.Insert a new lithium battery (CR2032) with the (+) pole upward as illustrated. Close the cover securely.
3.Press the AC button, and reset the speed scale and the clock time again according to "Main Unit
Preparation".
Replacing Battery
When the battery has worn out, replace it with a new one according to the following instruction.
Warning: Safely dispose of the old battery; and don't place it within children's reach. If swallowed
by mistake, consult a doctor immediately.
Battery Life: approx. one year (one hour's altitude measuring per day)
Note: If the display disappears with the press of the light button, or often shows irregular altitude, it means
the battery has worn out. Replace it with a new one.
Caution: Before replacing the battery, be sure to leave the unit for more than 5 minutes so that the power
saving function is on; in this way, it will update the data and memorize the newest measurements.
(Refer to page 13: "Power Saving Function".)
2. Main Unit Preparation
The following process must be completed before starting to use.
-1. How to Measure Wheel Circumference
In order to get the accurate value, measure the wheel circumference (L) actually from the tire of your
bicycle (Fig. 2). Put a mark on the tire tread, and ride one full wheel revolution; then mark the ground at the
end of one revolution and measure the distance between the two marks. Or, "Setting Values Cross Refer-
ence Table" (page 19) can tell the approximate wheel circumference according to the tire size.
-2. Setting Speed Scale
First, press the AC button; all displays illuminate and then "km/h" symbol appears (Fig.3). With each press
of the S/S button, "km/h" and "mile/h" appears alternately. Select the desired scale and press the Set
button to fix the scale. This speed scale corresponds to the altitude scale; if "km/h" is selected, the altitude
scale will be "meter", and if "mile/h" is selected, the altitude scale will be "feet".
