installation

Step 1: install the Battery –
Remove the battery cover from the bottom of the computer using a small coin
(Figure 1). Install the computer battery (3.0V/CR2032) with the positive (+) pole facing up. Replace the battery
cover and tighten. note: Replacing the battery will erase all stored information. When installing a new battery
after having used the computer, make sure to write down the odometer value before changing the battery so
you can later re-enter it in the computer.
Step 2: install the Magnet to the Wheel–
Clamp the magnet to a spoke on the right side of the front
wheel (Figure 2). Make sure that the magnet is facing the outside of the wheel so that the flat side of the
magnet passes in front of the sensor.
Step 3: attach the Sensor to the Fork–
Attach the computer sensor to the right fork leg using two of the
cable ties provided. Make sure the metal side of the sensor is facing the wheel. Do not fully secure the cable
ties yet, as the sensor location may require further adjustment (Figure 3). Adjust the sensor and magnet loca-
tion so that clearance between the two is no greater than 2mm. (Figure 4). The magnet should now pass by
the tip of the sensor when the wheel rotates.
Step 4: install the Mounting Bracket & Computer–
Attach the mounting bracket to the handlebar by
using the remaining 2 cable ties as shown in (Figure 4). Make sure the mounting bracket is clamped tightly
and will not slip on the handlebar. Insert the computer into the mounting bracket (Figure 5). When adjustments
have been made and the computer operates correctly, tighten completely all nuts and bolts.
