Water Resistance Of Polar Products - Polar Electro Vantage M User Manual

iOS devices with iOS 11 or later
•
Android mobile devices with Bluetooth 4.0 capability and Android 5 or later (check full phone spe-
cification from your phone manufacturer)
There is plenty of variation between how different Android devices handle the technologies used in our
products and services, such as Bluetooth Low Energy (BLE) and different standards and protocols.
Because of this, compatibility varies between phone manufacturers, and unfortunately Polar cannot
guarantee that all features can be used with all devices.

WATER RESISTANCE OF POLAR PRODUCTS

Most Polar products can be worn when swimming. They are not, however, diving instruments. To main-
tain water resistance, do not press the buttons of the device under water. When measuring heart rate in
water with a GymLink compatible Polar device and heart rate sensor, you may experience interference
for the following reasons:
Pool water with high chlorine content, and seawater are very conductive. The electrodes of the
l
heart rate sensor may short-circuit, preventing ECG signals from being detected by the heart rate
sensor.
Jumping into water or strenuous muscle movement during competitive swimming may shift the
l
heart rate sensor to a location on the body where ECG signals cannot be picked up.
The ECG signal strength is individual and may vary depending on the individual's tissue com-
l
position. Problems occur more frequently when measuring heart rate in water.
In the watch industry, water resistance is generally indicated as meters, which means the static water
pressure of that depth. Polar uses this same indication system. Water resistance of Polar products is
tested according to International Standard ISO 22810 or IEC60529. Every Polar device that has water
resistance indication is tested before the delivery to stand water pressure.
Polar products are divided into four different categories according to their water resistance. Check the
back of your Polar product for the water resistance category, and compare it to the chart below. Please
note that these definitions do not necessarily apply to products of other manufacturers.
When performing any underwater activity, the dynamic pressure generated by moving in water is greater
than the static pressure. This means that moving the product under water subjects it to a greater pres-
sure than if the product were stationary.
