Heart Rate Measurement; Water Resistance; Service And Maintenance - Nokia Steel HR Installation And Operating Instructions Manual

Heart Rate Measurement

• Skin perfusion, or how much blood is flowing through the skin, varies among individuals
and according to the environment. In certain circumstances, the Withings Steel HR may
not be able to provide an accurate heart rate measurement.
• The technology used by the Withings Steel HR is based on the light absorbed by your
skin and blood. Any permanent or temporary changes to your skin, such as tattoos,
sweat, or even hair on the wrist may affect the measurements.
• Environmental factors may affect the ability of the Withings Steel HR to take an
accurate measurement. For example, water may obstruct or modify the light
dispersion, and cold weather may impact skin perfusion.
• The Nokia Steel HR™ needs to stay securely in place to provide a heart rate
measurement. Activities that cause force to the wrist, such as boxing or volleyball, may
not allow the Withings Steel HR to provide an accurate heart rate measurement.

Water Resistance

• Your Nokia Steel HR™ can withstand a pressure similar to that of a 50 m (165 ft) depth.
You can, therefore, use it when dishwashing, splashing or swimming. However,
it can't be used for diving or snorkeling.
• Do not press the button of your watch when it is under water
• Avoid long exposure to salt water. Make sure you rinse your watch with fresh water
after spending time swimming in salted water.
• Avoid exposure to any chemical products such as solvents, detergents, perfumes
or cosmetics. They may damage the wristband or the casing of the watch.
• Avoid extreme atmospheres (e.g., saunas or steam rooms).

Service and Maintenance

• Do not attempt to repair or modify your Nokia Steel HR™ yourself. Service and
maintenance not described in this User Guide should be performed by professional
technicians.
• Exposure to high or low temperatures may shorten battery life.
• The aging of the materials may affect the water resistance of the watch.
Water resistance cannot be permanently guaranteed.
