IMPORTANT INFORMATION
BATTERIES
The Polar V650 training device has an internal, rechargable battery. Rechargeable batteries have a limited
number of charge cycles. You can charge and discharge the battery over 300 times before a notable decrease
in its capacity. The number of charge cycles also varies according to use and operating conditions.
At the end of the working life of the product 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.
The Polar Bluetooth Smart® heart rate sensor has a user changeable battery. To change the battery yourself,
please follow the instructions carefully as instructed in chapter Change the Heart Rate Sensor Battery.
The batteries for the speed sensor Bluetooth Smart® , and cadence sensor Bluetooth Smart® cannot be
replaced. Polar has designed the sensors to be sealed in order to maximize mechanical longevity and reli-
ability. The sensors have long-life batteries inside. To purchase a new sensor contact your authorized Polar
Service Center or retailer.
Keep the batteries away from children. If swallowed, contact a doctor immediately. Batteries should be dis-
posed of properly according to local regulations.
CHANGE THE HEART RATE SENSOR BATTERY
To change the battery of the heart rate sensor yourself, carefully follow the instructions below:
When changing the battery, make sure the sealing ring is not damaged, in which case you should replace it
with a new one. You can purchase the sealing ring/battery kits at well-equipped Polar retailers and authorized
Polar Services. In the USA and Canada, the additional sealing rings are available at authorized Polar Service
Centers. In the USA the sealing ring/battery kits are also available at www.shoppolar.com.
When handling a new, fully charged battery, avoid clasp-like contact, i.e. simultaneously from both sides, with
metal or electrically conducting tools, like tweezers. This may short circuit the battery, causing it to discharge
more rapidly. Typically, short circuiting does not damage the battery, but it may decrease the capacity and the
lifetime of the battery.
