THE RECEIVER

• Keep your unit clean.

• Wipe off any moisture before putting the unit away.

• Do not store the unit in non-breathable material (i.e. plastic bag or damp gym bag). Keep your Polar Heart Rate Monitor out of extreme cold (below –10 ºC/14 ºF) and heat (above 50 ºC/120 ºF).

THE TRANSMITTER

• Wash and dry your transmitter after use. To maximize the battery life, do not store your transmitter in a damp environment or with conductive material such as a wet towel.

• Readjust the elastic strap periodically so that the transmitter fits firmly around the chest.

• Clean the transmitter belt regularly with a mild soap and water solution. Never use alcohol or any abrasive material such as steel wool or cleaning chemicals on any part of the HRM.

• Wearlink transmitters should be completely removed (both sides) from the electrode belt prior to storing.

Basic Troubleshooting – I can’t get a HRM signal

If you are having difficulty with the transmitter it may be due to one of the following reasons:

Electrical Interference: Erratic readings on the receiver are usually caused by interference. If the heart rate readings appear to be abnormal, check that your Polar HRM is not within range of other strong electromagnetic signals. Common sources are televisions, computers, cars, cellphones, TV antennas, high voltage power lines (both above and below ground) and some exercise equipment. Re-locating the position of the wrist receiver can usually solve this problem.

To find a location that has no interference, remove the chest transmitter and exercise as usual. If the heart symbol continues to flash, you are picking up interference. In this case, move the wrist receiver to a location where it does not flash, then put on your chest transmitter. In most cases when the interference is cause by a piece of exercise equipment, placing the wrist receiver on the side rail, away from the front electronics display of the equipment will correct the problem.

Please note: Static electricity in clothing or a flapping shirt can cause false readings, some items of clothing, i.e. man-made fibers, could be the cause. Please try wetting the T-shirt in the area where the transmitter is.

Coded transmitters greatly reduces crosstalk between heart rate monitors so you do not pick up another person’s heart rate reading on your wrist receiver(see section on coding below). The coded transmission does not eliminate or reduce interference from electrical sources as described above.

Poor Conductivity: It is important that the electrodes are wet during the heart rate measurement mode. To moisten the electrodes on the Wearlink transmitter belt place the electrodes under running water. If water does not ensure the flawless transmission, you can use water-soluble conductive cream instead. If you choose to use a conductive cream, apply it to the ribbed-area of the transmitter only or on the silver-mesh area for the Wearlink.

Once wet, check that the electrode areas are firmly against your skin, just below the pectoral muscles. The Polar logo should be in a central, upright position.

Dirty Electrodes: The transmitter electrodes should be cleaned with a mild soap and water solution and thoroughly dried after each use. Try cleaning the electrodes and test the transmitter again.

Positioning: If the electrodes are clean and moist, and there is still no heart rate registering on the receiver, try to shift the transmitter around to the side of your body (try the left side first) or position it lower or higher on the chest. In some cases, you can try the transmitter on your back, however, the belt must then be worn with the Polar logo upside down and facing out. This ensures that the left electrode stays on the left side of the body and the right electrode stays on the right side of the body. Make sure to wet the electrodes every time it is moved to a new position.

Medical Condition: There are a very small number of cases where a Polar HRM will not work due to a medical condition, for example: low voltage R-wave signals; atrial fibrillation or bundle branch blocks.

To determine if the transmitter is functioning properly, you can have another person try the monitor.

Coded Heart Rate Transmission: Polar coded transmitter automatically locks in a code to transmit your heart rate to the wrist receiver. In a coded transmission the receiver accepts heart rate data only from the Polar coded transmitter. Coding significantly reduces crosstalk from other heart rate monitors. However, it does not necessarily reduce all environmental interference.

Once you press the OK/Start button to start measuring your heart rate, a heart symbol will begin flashing and your heart rate will appear in beats per minute. If you have successfully locked in the code, you will see an outline around the flashing heart
