IMPORTANT INFORMATION
CARE AND MAINTENANCE
Keep the sensor clean. Clean it with a mild soap and water solution, and rinse off with clean water. Dry it carefully with a
soft towel. Never use alcohol or any abrasive material, such as steel wool or cleaning chemicals. Do not immerse the sensor
in water.
Your safety is important to us. Make sure the sensor does not disturb pedaling or using the brakes or gears. While riding
your bike, keep your eyes on the road to prevent possible accidents and injury. Avoid hard hits as these may damage the
sensor.
Replacement magnet sets can be purchased separately.
CADENCE SENSOR BATTERY
The battery cannot be replaced. The sensor is sealed in order to maximize mechanical longevity and reliability. To purchase
a new sensor, contact your authorized Polar Service or retailer. You can also purchase sensors online. Go to
www.polar.com to find your own country's shoppolar online store.
The battery level of your sensor is displayed on the receiving device if it supports Bluetooth® Battery Service.
To increase battery life, the sensor goes into standby mode in thirty minutes if you stop cycling and the magnet is not
passing the sensor.
FREQUENTLY ASKED QUESTIONS
What should I do if...
...the cadence reading is 0 or there is no cadence reading while cycling?
l Make sure the position and distance of the cadence sensor to the crank magnet are appropriate.
l Check that you have activated the cadence function in the receiving device. For further information, see the user
guidance material of the receiving device or mobile application.
l Try keeping the receiving device in a bike mount on the handlebar. This may improve the connection.
l If the 0 reading appears irregularly, this may be due to temporary electromagnetic interference in your current
surroundings.
l If the 0 reading is constant, the battery may be empty.
...there are irregular cadence or heart rate readings?
l Disturbance may occur near microwave ovens and computers. Also WLAN base stations may cause interference
when training with Polar Cadence Sensor. To avoid erratic reading or misbehaviors, move away from possible
sources of disturbance.
... I want to pair the sensor with the receiving device before installation?
l Follow the instructions in the user guidance material of the receiving device or mobile application. Instead of
rotating the crank, activate the sensor by moving it back and forth close to the magnet. The flashing red light
indicates that the sensor is activated.
