Wahoo Fitness Key for iPhone

1. Download the Wahoo Fitness Utility App from iTunes 
2. Insert the Wahoo Key securely into the 30 pin connector at bottom of iPhone, iPad, or iPod touch. 
3. Open the Wahoo Fitness Utility App and select the Sensor Tab 
4. Select the sensor you would like to pair with the iPhone, iPad, or iPod touch. Make sure the sensor is within 5' of the Wahoo Key. 
5. Done! Your sensor is connected and will show data from the sensor, the signal strength and the serial number of your sensor. Since most ANT+ sensors 'sleep' when not in use, you may have to 'awaken' it- for example, a stride sensor can be activated by taking a few steps. 

Not working? 

1. When the iPhone doesn't register the Wahoo Key it is almost always caused by dust, lint, or other debris in the 30-pin connector. Try using canned air or a flat style toothpick to clean the 30 pin connector. 
2. Try using the Wahoo Key with a different iPhone to make sure the phone isn't the problem.
