Speed Sensor and Cadence Sensor Instructions

WARNING

See the Important Safety and Product Information guide in the product box for product warnings and other important information.

Installing the Speed Sensor

NOTE: If you do not have this sensor, you can skip this task.
TIP: Garmin® recommends you secure your bike on a stand while installing the sensor.

Place and hold the speed sensor on top of the wheel hub.
Pull the strap (1) around the wheel hub, and attach it to the hook (2) on the sensor.

The sensor may be tilted when installed on an asymmetrical hub. This does not affect operation.

Rotate the wheel to check for clearance.
The sensor should not contact other parts of your bike.
NOTE: The LED flashes green for five seconds to indicate activity after two revolutions.

TIP: Garmin recommends you secure your bike on a stand while installing the sensor.

Select the band size that fits your crank arm securely.
The band you select should be the smallest one that stretches across the crank arm.
On the non-drive side, place and hold the flat side of the cadence sensor on the inside of the crank arm.
Pull the bands around the crank arm, and attach them to the hooks on the sensor.
Rotate the crank arm to check for clearance.
The sensor and bands should not contact any part of your bike or shoe.
NOTE: The LED flashes green for five seconds to indicate activity after two revolutions.
Take a 15 minute test ride and inspect the sensor and bands to ensure there is no evidence of damage.

Pairing the Sensors with Your Device

Pairing is the process of connecting an ANT+® wireless sensor, like your speed sensor or cadence sensor, with a Garmin ANT+ compatible device.

NOTE: The pairing instructions differ for each Garmin compatible device. See your owner’s manual.

Bring the Garmin compatible device within 3 m of the ANT+ sensor.
Stay 10 m away from other ANT+ sensors while pairing.

After you pair the first time, your Garmin compatible device automatically recognizes the ANT+ sensor each time it is activated.
