heart rate monitorSensor PairingWhat is pairing?Pairing is the process of matching sensors, like your heart ratemonitor, with your compatible GPS device. This process occursautomatically when you turn on your GPS device and only takesa few seconds when the sensors are functioning correctly. Oncepaired, your GPS device will only receive data from your sensor.Pairing tips:• Position your GPS device within 3 meters of the sensor whilepairing.• Stay far away from any other sensors while pairing.• Restart scan if your GPS device appears to be paired withanother sensor.• Make sure to enable the sensors on your GPS device.• Reapply moisture to the sensors on the heart rate monitor. Useelectrode gel, water, or saliva.• Replace the battery.• Clean the sensors. Dirt and sweat build-up on the sensor canweaken signals.SpecificationsPhysical size: 13.7”W x 1.4”H x 0.5”DTransmission range: approximately 3 mBattery: CR2032 (3 volts)Battery life: approximately 3 years (1 hour per day)Weight: 21 gReplacing the BatteryThe heart rate monitor contains a user-replaceable CR2032battery.
