Changing Batteries

Training Computer Battery

Do not open the training computer yourself. We recommend that you have the battery replaced by an authorized Polar Service Center. They test your Polar FT1/FT2 for water resistance after battery replacement and make a full periodic check. Please note the following:

  • The low battery indicator is displayed when 10-15% of the battery capacity is left.

  • Excessive use of the back light drains the battery more rapidly.

  • In cold conditions, the low battery indicator may appear, but will disappear when the temperature rises.

  • The back light and sound are automatically turned off when the low battery indicator is displayed.

Transmitter Battery

If you suspect that the transmitter battery has discharged, contact your authorized Polar Service Center for a replacement transmitter.

The Polar training computer shows your performance indicators. Polar training computer is designed to indicate the level of physiological strain and recovery during and after exercise session. No other use is intended or implied.

The Polar training computer should not be used for obtaining environmental measurements that require professional or industrial precision.

Minimizing risks when exercising

Exercise may include some risk. Before beginning a regular exercise program, it is recommended that you answer the following questions concerning your health status. If you answer yes to any of these questions, we recommend that you consult a doctor before starting any training program.

  • Have you been physically inactive for the past five years?

  • Do you have high blood pressure or high blood cholesterol?

  • Do you have symptoms of any disease?

  • Are you taking any blood pressure or heart medication?

  • Do you have a history of breathing problems?

  • Are you recovering from a serious illness or medical treatment?

  • Do you use a pacemaker or other implanted electronic device?

  • Do you smoke?

  • Are you pregnant?

In addition to exercise intensity, medications for heart conditions, blood pressure, psychological conditions, asthma, breathing, etc., as well as some energy drinks, drugs, alcohol, and nicotine may also affect heart rate.

It is important to be sensitive to your body’s responses during exercise. If you feel unexpected pain or excessive fatigue when exercising, it is recommended that you stop the exercise or continue at a lighter intensity.

Note! If you are using a pacemaker, you can use Polar training computers. In theory interference to pacemaker caused by Polar products should not be possible. In practice no reports exist to suggest anyone ever having experienced interference. We cannot however issue an official guarantee on our products’ suitability with all pacemakers or other implanted devices due to the variety of devices available. If you have any doubts, or if you experience any unusual sensations while using Polar products, please consult your physician or contact the implanted electronic device manufacturer to determine safety in your case.

If you are allergic to any substance that comes into contact with your skin or if you suspect an allergic reaction due to using the product, check the listed materials in Technical Specifications. In case of any skin reaction, stop using the product and consult your physician.

The combined impact of moisture and intense abrasion may cause a black color to come off the heart rate sensor’s surface, possibly staining light-colored clothes. If you use perfume or insect repellent on your skin, you must ensure that it does not come into contact with the training computer or the heart rate sensor.

If you train in cold conditions (-20 °C to -10 °C / -4 °F to 14 °F ) we recommend that you wear the training computer under the sleeve of your jacket, directly on your skin.

Exercise equipment with electronic components may cause interfering stray signals.

To tackle these problems, try the following:

  1. Remove the heart rate sensor from your chest and use the exercise equipment as you would normally.

  2. Move the training computer around until you find an area in which it displays no stray reading or does not flash the heart symbol. Interference is often worst right in front of the display panel of the equipment, while the left or right side of the display is relatively free of disturbance.

  3. Put the heart rate sensor back on your chest and keep the training computer in this interference-free area as much as possible.

If your training computer still does not work, the piece of equipment may be electrically too noisy for wireless heart rate measurement.

Water Resistance of the FT1/FT2 Training Computer

FT1 and FT2 training computers may be worn when swimming. To maintain water resistance, do not press the button under water. For more information, visit http://www.polar.com/support. Water resistance of Polar products is tested according to International Standard ISO 2281. Products are divided into three categories according to their water resistance. Check the back of your Polar product for the water resistance category, and compare it to the chart below. Please note that these definitions do not necessarily apply to products of other manufacturers.

If you've lost your way in the menu, press and hold the button until time of day is displayed.

If the heart rate reading becomes erratic, extremely high or shows nil (00), make sure that there are no other heart rate transmitters within 1 m/3 ft and that the transmitter fits snugly and is moistened, clean and undamaged.

Strong electromagnetic signals can cause erratic readings. Electromagnetic disturbances may occur near exercise equipment with electronic components, high-voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams, televisions, car motors, bike computers, some motor-driven exercise equipment, cellular phones, or at electric security gates.

If the abnormal reading continues despite moving away from the source of disturbance, slow down and check your pulse manually.

If you feel it corresponds to the high reading on the display, you may be experiencing cardiac arrhythmia. Most cases of arrhythmia are not serious, but consult your doctor nevertheless.

A cardiac event may have altered your ECG waveform. In this case, consult your physician.

If heart rate measurement does not work despite the actions mentioned previously, the battery of your heart rate sensor may be empty.

Troubleshooting Checklist

If you experience difficulties with heart rate measuremant, consider the following:

  1. Is the heart rate sensor worn correctly? The belt should be worn flat and tight but comfortably against the skin with the text visible and in upright position.

  2. Make sure the electrodes of the heart rate sensor are clean and well-moistened.

  3. The training computer must be within one-meter / three feet from the heart rate sensor. The training computer picks up sensor signals within one meter / three feet.

  4. Are the heart rate signals very high and abnormal? Relocating the training computer may help. Disturbance can also be caused by other heart rate monitors or training equipment nearby (see Precautions for further information).

  5. The chemicals in seawater and some swimming pools may affect the ECG signal pick-up. Pool water with high chlorine content, and seawater are very conductive. The electrodes of the heart rate sensor may short-circuit, preventing ECG signals from being detected by the heart rate sensor. Jumping into water or strenuous muscle movement during competitive swimming may shift the heart rate sensor to a location on the body where ECG signals cannot be picked up. The ECG signal strength is individual and may vary depending on the individual’s tissue composition. Problems occur more frequently when measuring heart rate in water.

  6. The battery of your training computer may be low even if the low battery symbol is not yet visible.

  7. The battery of your heart rate sensor may be empty.
