Battery Life & Charging

The Polar A370 can last up to 4 days on average without needing to be charged. Battery life depends on how much you use the device, and how many alerts and notifications you get. Heavier use means lower runtimes. Under most normal conditions, the battery will last 4 days.

The Polar A370 has some pretty specific charging requirements:

  • Only use a power adapter that's labeled "5Vdc" and that provides a minimum of 500mA
  • Don't use a 9 volt charger when charging your device, as this can damage the Polar A370.
  • When charging from a computer, only use the USB cable that came with the Polar A370, as it has been specifically designed for this purpose.

Care Instructions

If you regularly sweat due to yard work, exercising, or other physical exertion; you should clean the device with mild soap and water. You should also clean your wrist. The watchband detaches from the watch, allowing you to clean both separately. For cleaning, use mild soap and water to clean.

Do not use toxic chemicals or household cleaner to clean the watch. Do not scrub with steel wool or other abrasive material.

Wipe dry with a soft towel.

Wearing Instructions

For a reliable heart rate measurement and calorie accuracy you need to make sure that the heart rate sensor is in contact with your skin. This means it can't be too loose on the wrist. For best results, make sure there's a finger's width gap between the wrist bone and the watch. This will ensure the watch is fitting correctly on the wrist and it's able to get the best measurement.

Bluetooth Connectivity: Snycing This Device With the App and Online

To make the device to connect with your Polar Flow App for your Android or iPhone, please follow these instructions:

  1. Make sure you have the Polar Flow app running.
  2. Press and hold the side button until you see the word "Searching" display on the A370 display.
  3. The device will display the words "Searching", "Connecting", "Syncing", and "Completed" during and after a successful sync.
  4. After successfully synching the device to the app, you'll see the daily activity view and the training diary.

Bluetooth Connectivity: Troubleshooting Tips

If you're having trouble syncing, turn the Bluetooth off and turn it back on. If that doesn't work, you should try turning off the mobile device and then turning it back on again. As a last resort, uninstall the app and reinstall it.

Does the Polar A370 Track Steps?

The Polar A370 counts steps and calories burned. It will also compute a distance total as you go through your day, and let you know how many miles you've walked.

How to Change the Time on the Polar A370?

The current time is synced to your computers system clock, when you connect your Polar A370 to the Polar Flow Web Service. To sync with the Polar Flow Web Service, you'll need to have a Polar account, and you'll need to have the Flow App installed on your phone. Once those things are taken care of, you'll need to follow these instructions:

  1. Sign into the Flow App, and press and hold the button on your A370.
  2. You should see your screen change to "searching.. connecting... syncing..." This is normal and it's how the watch connects to your phone.
  3. "Completed" is what's displayed when you're done.
  4. By connecting to the Flow App, you'll automatically be set to the correct time.
How Long Do I Need to Sleep Before I Start to See Sleep Metrics?
In order to see sleep data, you'll need to sleep for 4 hours.
Does the Sleep Tracking Technology Measure Sleep Quality of Naps?
Since most naps are not 4 hours long, you won't be able to see sleep data from naps.
What if I Sleep During the Day?
If you work the night shift and sleep during the day, the A370 will still be able to track your sleep progress, as the tracker does not factor daylight into its determination that you are asleep. When you wake up in the evening, you should be able to see your data, from the previous sleep period.
Can You Use the Polar A370 While Swimming?
Yes, the A370 will work in water, up to 30 meters deep. Water can sometimes prevent the heart rate tracking from working as well as it does on dry skin.
