Automatic pairing to Polar dual transmitters
(H7/H10)
Selected Polar Smart coaching features
included
Polar API available
DESCRIPTION
Polar 2R –platform incorporates several key features into one simple package that can be
interfaced either by UART or by USB. The API is also available for several different operating
systems.
The platform includes Bluetooth Smart, 5 kHz receiver system and the contact heart rate –
function. It comes with selected coaching features that are available when compatible transmitter
belt is used. To be noted, coaching features require heart rate variability and not all transmitters
support that.
It is possible to perform auto-pairing to Polar H7 and H10 transmitters. This means when user
wears H7 or H10 and he/she walks to fitness equipment, the 5 kHz system detects the transmitter
and the transmission code. Then platform scans for Bluetooth sensors and when a match of this
data is found, the system connects to this particular Bluetooth transmitter. For the user this action
is invisible.
The platform has software update possibility.
The available options are listed on the last page of this datasheet. Please contact your local sales
representative to discuss your requirements. Contact information is found on the footer of each
page.

USA
Polar Electro Oy has not approved any changes or modifications to this device by the user. Any changes or modifi cations could void
the user’s authority to operate the equipment.
FCC regulatory information
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired
operation.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
4. Consult the dealer or an experienced radio/ TV technician for help.
This product emits radio frequency energy, but the radiated output power of this device is far below the FCC radio frequency exposure
limits. This equipment complies with FCC RF radiation exposure limits forth for an uncontrolled environment. Nevertheless, the
device should be used in such a manner that the potential for human contact with the antenna during normal operation is minimized.
