POLAR M91 TI (01) PDF Document

The POLAR M91 TI heart rate monitor consists of three main parts:

1. The POLAR M91 TI Wrist Receiver: Displays your heart rate and other exercise data.

2. The T31 Transmitter: Consists of an electrode strap and a connector. It detects your heart rate and transmits it to the wrist receiver.

3. The Bike Mount: An accessory to attach your wrist receiver to your bicycle.

To ensure accurate heart rate measurement with your POLAR M91 TI, follow these steps to wear the T31 transmitter:

1. Attach one side of the transmitter to the elastic strap.

2. Wet the grooved electrode areas on the back of the transmitter thoroughly with water.

3. Adjust the strap length to be snug but comfortable.

4. Secure the strap around your chest, just below the pectoral muscles, and attach the other end of the transmitter.

5. Center the transmitter in the middle of your chest, with the Polar logo in an upright position.

6. Lift the transmitter from your chest and re-moisten the electrode areas to ensure good skin contact.

It is important to wear the transmitter directly on your skin. The transmitter automatically activates when it detects heart beats and deactivates a few minutes after you take it off.

– After each use, detach the connector from the strap and rinse the strap under running water.

– Wash the strap regularly in a mild soap and water solution. It is not suitable for machine washing or drying.

– Dry the connector carefully with a soft towel.

– Never store the transmitter wet. Sweat and moisture can keep the electrodes wet and the transmitter activated, which shortens battery life.

Please observe the following precautions when using your POLAR M91 TI:

– Individuals with a pacemaker, defibrillator, or other implanted electronic device use the POLAR M91 TI at their own risk. It is recommended to perform an exercise stress test under a doctor’s supervision before use to ensure the safety and reliability of the pacemaker and heart rate monitor being used simultaneously.

– If you have any allergic skin reactions to materials touching your skin, check the material specifications. To avoid reactions from the transmitter belt, wear it over a shirt, but moisten the shirt well under the electrodes.

– The combined effect of moisture and intense abrasion may cause a black color to come off the transmitter’s surface, which could stain light-colored clothes.

– If using insect repellent on your skin, ensure it does not come into contact with the heart rate monitor.

– Minimize electromagnetic interference by avoiding strong sources like high-voltage power lines, televisions, mobile phones, and open-air antennae.

If you experience issues with your heart rate reading on the POLAR M91 TI, try the following troubleshooting steps:

1. Check that the transmitter belt is snug and the electrodes on the back of the transmitter are well-moistened and placed correctly against your skin.

2. Ensure the POLAR M91 TI wrist receiver is within the 3 feet / 1 meter transmission range and is not being shielded by your body.

3. Make sure there are no other heart rate monitor transmitters within the transmission range, as they can cause interference.

4. Check that your heart rate is within the measurable range (20-240 bpm).

5. Strong electromagnetic signals can cause erratic readings. Try moving away from potential sources of disturbance, such as high-voltage power lines, televisions, or mobile phones.

6. Cardiac arrhythmia can cause irregular readings. If this is a concern, consult your physician.

7. If the reading is frozen, try resetting the wrist receiver by pressing all four side buttons (SIGNAL, LIGHT, UP, DOWN) simultaneously for 2 seconds. All settings will be saved.
