The BKM4 Bike Speed+Cadence Monitor mounts easily onto a bike frame. The speed monitoring unit is

positioned on the back of the rear triangle; the cadence monitoring unit is positioned on the bottom of the

rear triangle. One bike magnet pickup is attached to a spoke for use with the speed monitoring unit; the

other is attached to the inside of the crank arm for use with the cadence monitoring unit.

• Attach all pieces securely. Any sliding motion will affect accuracy.

• The bike magnet pickups must pass across the monitoring units. Misalignment will affect accuracy.

The BKM4 Bike Speed+Cadence Monitor must “pair” with an ANT-enabled sports monitoring watch in

order to display performance data to the user. To pair your monitor:

• Bring the BKM4 Bike Speed+Cadence Monitor within 10-30 inches (25-75 cm) of the sports

monitoring watch.

• Ensure that you are standing at least 72 inches (183 cm) away from any other ANT-enabled bike

speed or cadence monitor. You can be in proximity to other ANT-enabled devices.

• After the BKM4 Bike Speed+Cadence Monitor pairs with the sports monitoring watch, the bike icon

appears on the watch’s LCD display.
