BATTERY AND CHARGING

At the end of the product's working life Polar encourages you to minimize possible effects of waste on the
environment and human health by following local waste disposal regulations and, where possible, utilizing sep-
arate collection of electronic devices. Do not dispose of this product as unsorted municipal waste.
Polar Loop Crystal has an internal, rechargable battery. When fully charged, Polar Loop Crystal can hold its
charge up to 8 days, depending on the usage. For example, if you browse the display a lot or use your Polar
Loop Crystal for heart rate training, you need to charge the battery more often.
Use the USB cable included in the product set to charge your Polar Loop Crystal via the USB connector on
your computer. If you want to plug the USB connector to a wall outlet, use a USB power adapter (not included
in the sales package). If the battery has drained and the display doesn't light up after plugging in, it may take
up to 20 seconds for the charging animation to appear. The display will rotate between the charging symbol
and the battery level percentage as it charges to 100%. It takes approximately 90 minutes to fully charge the
battery.
If you use an AC adapter, make sure that the adapter is marked with "output 5Vdc 0.5A - 2A max". Only use
an AC adapter which is adequately safety approved (marked with "LPS", "Limited Power Supply" or "UL lis-
ted").
You Polar Loop Crystal notifies you when the battery charging level goes low. For more information about low
battery notifications, see Display messages.
