Go Wireless® Heart Rate (GW-HR)Specifications and User Guide

– Primary Test: Ensure that the Polar Transmitter Module is attached to the Heart Rate Hand Grips securely. Locate and record the ID on the side of the Polar Transmitter Module. This is a unique sequence of numbers and/or letters (e.g., ID:XXXXXXXX). Have the subject grasp the handles of the Go Wireless Heart Rate to activate the Bluetooth radio in the Polar Transmitter Module. The sensor is now ready for data collection.

Collecting Data with Graphical Analysis: Launch Graphical Analysis, select Sensor Data Collection. Select the Polar HR with the proper ID from the list of available sensors. Verify that heart rate is displayed and is stable. Tap collect to begin data collection.

Note: The sensor will disconnect from the device 30 seconds after letting go of the hand-grips. 

As units approach their third and fourth year of service, the battery in the module will need to be changed. The battery is a CR 2025, available at most drug stores. Please be sure to dispose of the old battery properly. To find a battery disposal facility near you, visit http://www.rbrc.org/
