The heart rate reading is absent or is totally erratic.
Resolution 1: Ensure Good Contact Between the Skin and Electrodes
- Repeat the electrode wetting procedure by wetting the two grooved rectangular areas on the underside of the Belt Transmitter thoroughly with water or saliva. The electrodes must be wet to pick up accurate heart rate readings.
- Make sure the transmitter is centered with electrodes flat against your skin, as high under the pectoral muscles as is comfortable.
- Wash your belt transmitter with mild soap and water, if you have not been doing so regularly.
Resolution 2: Check the Distance Between the Receiver and Transmitter
Make sure your heart rate receiver is within the proper range to receive transmission (1 meter/3 feet from your chest belt).
Resolution 3: Ensure Good Cable Connections
- Check the cable connection on the back of the PM where the receiver cable plugs in and make sure the cable is securely plugged in.
- Check the connection between the cable and the receiver and make sure it is secure.
Resolution 4: Limit Outside Interference
If you are exercising within range of strong electromagnetic signals, the heart rate readings may elevate to abnormal levels. Common sources of electromagnetic signals are televisions, computers, cars, TV antennas, high voltage power lines and motor driven exercise equipment.
Resolution 5: Limit Signals from Other Belts
Signals from more than one belt transmitter within the transmission range (1 meter/3 feet) can cause incorrect readings.
Check your surroundings and move away from the source of interference if possible. Two indoor rowers with heart rate hardware must be at least 4 feet (1.22 meters) apart to avoid interference.
