Troubleshooting
- Heart rate does not show up: Make sure that you have good contacts between the electrodes and your skin. Remoisten the electrodes. Make sure your chest belt fits securely and properly positioned at the center of the chest. Or, the transmitter battery may be worn-out. Replace the battery. Make sure the battery is installed correctly with the (+) side facing up.
- Display is blank or very dim: The watch battery power may be low, try a new battery. Make sure the battery is installed correctly.
- Display becomes dark or black: The watch is too hot. Place the unit in a shaded area, and it should turn normal after a while.
- The unit operates slowly or sluggishly: The unit is too cold. Warm the unit, and it should turn normal.
- Heart rate varies widely: Make sure your chest belt fits securely and is properly positioned at the center of the chest (refer to the Transmitter & Elastic Strap section in the manual). Check your surroundings for electromagnetic or high energy interference and move away from the source of interference.
