Monitor Goes Blank
Symptom: The entire Performance Monitor screen (not just heart rate display) goes blank when the heart rate cable is plugged in.
Resolution: This is generally caused by a short-circuit that occurs if the heart rate cable is plugged into the PM while the monitor is turned on. If the heart rate cable is still plugged into the PM:
- Push ON/OFF once to turn the PM off.
- Push ON/OFF again to turn the PM back on again.
If you removed the heart rate cable when the screen went blank:
- Push ON/OFF once to turn the PM off.
- Plug the heart rate cable into the monitor.
- Push ON/OFF again to turn the PM back on again.
We recommend plugging the heart rate cable in only when the PM is off.
