TROUBLESHOOTING
Performing a Self-Test can quickly diagnose problems with the Power Meter.
Perform a Self-Test by back-pedaling one or more times, and then observe the LED.
• Zero blinks: Dead battery, or magnet not installed.
• 1 long blink: Self check pass. Head unit paired.
• 2 short blinks: Self check pass. No head unit paired.
• 3 short blinks: Self check Fail. Reed switch Failure.
• 4 short blinks: Self check Fail. Bad Strain Gauge.
Power Meter does not pair with the computer
• Check the battery. The battery must be installed correctly (“+” out) and have sufcient charge.
Make
sure the battery contact is free of corrosion.
• Check the magnet position.
Conrm the magnet is within 2-8 mm (1/16”-3/8”) of the sensor. The magnet
should be installed according to the instructions on pages 8-10. Once the cadence sensors have been
activated, the power meter will begin transmitting messages and is ready to be paired.
• Make sure the proper pairing technique has been followed for your bike computer. The pairing process
will vary by manufacturer. Refer to your bike computer’s instruction manual.
• If you are using a Garmin
®
bike computer with ANT+™ heart rate enabled, calibration will often be faster
when you are wearing the heart rate monitor/strap. Turn off the ANT+ HRM function if you are not using
a heart rate strap.
• Check with Quarq for the recommended rmware version for your Garmin computer. Follow the
instructions specic to your ANT+™ computer to check the installed rmware version.

Cadence, but no power
• Check the magnet position. The magnet should be installed according to the instructions on pages
8-10. Zero the power meter using Auto Zero or Manual Zero as described on pages 12-13.
• Remove any separate cadence or speed sensors.
Unusually high or low power values
1. Perform the Manual Zero as described on page
13.
2. If the Manual Zero is well outside +/- 500, check pre- and post- ride Zero Offset values.
3. If the pre- and post-ride Zero Offset values are greater than 50 points, it may be necessary
to contact Customer Support. Keeping a record of the Zero Offset values will be helpful when
contacting Customer Support.
• Remove third party cadence sensors. The Quarq delivers both power and cadence data to the bike
computer.
• Inspect and clean the chainrings and Quarq interface. Re-assemble according to the instructions on
page
14.
Manual Zero (Calibration) Fails
• When performing the Manual Zero procedure, make sure that the drive side crank arm is at the
6 o’clock position, there is no weight on the pedals, and the cranks are stationary.
• If you are using a Garmin
®
bike computer with ANT+™ heart rate enabled, calibration will often be faster
when you are wearing the heart rate monitor/strap. Turn off the ANT+ HRM function if you are not using
a heart rate strap.
Wireless Signal Disconnections
• Check the magnet position. The magnet should be installed within 2-8 mm (1/16”-3/8”) of the sensors,
according to the instructions on pages
8-10.
• Make sure the magnet is clean and free of debris.
• Check and replace the battery in the Quarq and/or bike computer.
• Make sure there is no moisture in the battery compartment.
