POLAR A370 Fitness Tracker with 24/7 Wrist-Based HR User Guide
How to get started
You can choose to set up your new Polar A370 either with (A) a mobile device or with (B) a computer, whichever is the most convenient for you. The A370 is in storage mode, and it wakes up in the setup. To get the most accurate and personal training and activity data, you must be precise with the settings in the setup. Plug your A370 into a powered USB port or a USB charger with a standard micro USB cable. It may take a few minutes for your A370 to wake up. Let your A370 charge during the setup.
If there is a firmware update available for your A370, we recommend you install it during the setup. It may take up to 10 minutes to complete.
A) SET UP WITH A MOBILE DEVICE AND POLAR FLOW APP

How to wear
A370 continuously measures heart rate from the wrist, in everyday wear, and during exercises. To get accurate heart rate readings, find a comfortable fit for your wrist by following these tips. In everyday wear, secure the wristband on top of your wrist, behind the wrist bone. Do NOT place the fitness tracker on top of the wrist bone.
The band can be slightly loose as long as the sensor on the back is touching your skin and stays in place when you move. Tighten the band a little bit when you start a training session, so the sensor will not move when you exercise. The wristband should not be uncomfortably tight either. Remember to loosen the wristband after training for a more comfortable fit.
Caring for your A370
Wash the A370 and your wrist daily to avoid any skin irritations. Dry your wrist and the wristband before you put it back on. Once in a while, take the tracker off and let your skin breathe. After swimming in seawater or heavy sweating, rinse the USB port under running water and let the USB port dry by leaving the cover open until it’s properly dry. Do not plug in the A370 (for a charge or sync) when the USB port is wet or sweaty. Charging a wet device damages the USB port, so don’t connect it even to your computer for a sync when it’s not dried up yet.
