Battery Installation

Remove the battery cover from the bottom of the computer, using a flat blade screwdriver. Install a AG13 battery with the positive (+) pole facing the battery cover and replace the cover. Should the LCD show irregular figures, take out the battery and install again.

Speedometer Sensor

The speedometer sensor bracket attaches to the left fork blade, using rubber shims to adjust to the diameter of the fork.

Position the sensor and magnet, making sure that the arc of the magnet intersects the alignment mark on the sensor with 1 mm clearance.

The magnet attaches to the front wheel spoke with the screws provided.

Mounting Computer Body

Attach the mounting shoe to the handlebar using the back splint provided. To check for proper speed function and sensor alignment, spin the front wheel with computer in speed mode. Adjust the position of sensor and magnet when there is no or weak reactivity.
