Installation

The speed sensor should be mounted on the fork, no more than 24" from the display unit.  The spoke magnet should be aligned with the line on the bottom edge of the sensor.

Batteries

The display unit uses a CR2032 coin cell battery.

When the display unit battery is replaced, all information stored on the display (odometer, timer) is erased.  If desired, take note of the information before replacing the battery.

The wheel speed sensor uses a 23A battery.
