Sensor Pairing

What is pairing?

Pairing is the process of matching sensors, like your GSC10, with 

your compatible GPS device. This process occurs automatically 

when you turn on your GPS device and only takes a few seconds 

when the sensors are on and functioning correctly. Once paired, 

your GPS device will only receive data from your sensor.

Pairing tips:

•  Position your GPS device within 3 meters of the sensor while 

pairing.

•  Stay far away from any other sensors while pairing. 
•  Restart scan if your GPS device appears to be paired with 

another sensor. 

•  Make sure to enable the sensors on your GPS device. 
•  Make sure the sensors are functioning correctly.
•  Replace the battery.
•  Clean the sensors. Dirt and sweat build-up on the sensors can 

weaken signals.

Replacing the Battery

1.  Locate the circular battery cover on the back of the heart 

rate monitor or the side of the GSC10. 

2.  Use a coin to twist the cover 

counter-clockwise until it 

is loose enough to remove 

(arrow points to unlocked). 

3.  Remove the cover, and 

replace the battery positive 

side up. Be careful not to 

damage or lose the o-ring 

gasket on the cover. 

4.  Use a coin to twist the cover 

back into place (arrow points 

to locked).

Note:

 Dispose of used battery 

properly.
