CARE AND MAINTENANCE INSTRUCTIONS
1. Avoid leaving the main unit exposed to direct sunlight
when not riding.
2. Once or twice a month, check the relative position and
gap of the sensor magnet and the transmitter housing to
ensure they have not moved.

not attempt to use thinners, alcohol or benzene as these
will damage the unit.
