• In exercise or sports, your heart naturally speeds up in pumping blood to the
body in accordance with your increased energy level. This watch can calculate
that increase expressed as the number of beats per minute (bpm) to determine a
safe target heart rate for each individual.
PRECAUTIONS/TIPS
1. A heart rate sensor is located on the back of the watch. The back sensor must
make firm contact with the user’s skin during Finger-Touch measurement.
2. There are 2 contacts located on the back of the chest strap. The sensors must
make firm contact with user’s skin during Chest-Strap measurement.
3. DO NOT take heart rate measurement when diving or under water.
4. Clean the back cover of the watch and the back of the chest strap occasionally by
applying a few drops of water and wipe it dry with a paper towel. It can help
removing any residual grease.
5. DO NOT use hand cream; it will insulate the signal between the skin and the
sensors.
6. Clean fingers with soap and water for better signal transmission.
7. Clean skin around chest area with soap and water for better signal transmission.
8. DO NOT use the fingertips where the skin is dry and thick.
9. For those with extremely dry skin, moisten the skin with tap water or apply a
conductive gel may help.
10. Hold the watch firmly when taking Finger-Touch measurement in motion.
11. Adjust the Chest Strap with the supplied elastic band until it is hold on your chest
firmly to avoid loosen it when doing exercise.
12. During the measurement, avoid any awkward motion. Awkward motion creates
undesired muscle noise; hence an incorrect heart rate reading may result.
