material (e.g. steel wool or cleaning chemicals).
Strap: Rinse the strap under running water after every use and hang to dry. Clean the strap gently with a mild
soap and water solution when needed. Do not use moisturizing soaps, because they can leave residue on the
strap. Do not soak, iron, dry clean or bleach the strap. Do not stretch the strap or bend the electrode areas
sharply.
Check the washing instructions on the label of the strap.
STRIDE SENSOR BLUETOOTH® SMART, SPEED SENSOR BLUETOOTH®
SMART AND CADENCE SENSOR BLUETOOTH® SMART
Clean the sensors with a mild soap and water solution and rinse them with clean water. To maintain the water
resistance, do not wash the sensors with a pressure washer. Do not immerse the speed sensor, cadence
sensor or stride sensor in water. Never use alcohol or any abrasive material such as steel wool or cleaning
chemicals. Avoid hard hits to the sensors, as these may damage the sensor units.
STORING
Keep your training device and sensors in a cool and dry place. Do not keep them in a damp environment, in
non-breathable material (a plastic bag or a sports bag) nor with conductive material (a wet towel). Do not
expose the training device to direct sunlight for extended periods, such as by leaving it in a car or mounted on
the bike mount.
It is recommended to store the training device partially or fully charged. The battery slowly loses its charge
when it is stored. If you are going to store the training device for several months, it is recommended to
recharge it after a few months. This will prolong the battery lifetime.
Dry and store the strap and the connector separately to maximize the heart rate sensor battery lifetime. Keep
the heart rate sensor in a cool and dry place. To prevent snap oxidation, do not store the heart rate sensor wet
in non-breathing material, such as a sports bag. Do not expose the heart rate sensor to direct sunlight for
extended periods
