Information is Power
By measuring intensity (heart rate) and duration (time) you can avoid over training, help prevent injury, and maximize your chances of achieving your goals.
Heart Rate Transmitter Your Heart Rate Transmitter reads the electrical impulses of your heart and transmits data to your watch. It is one of the most accurate ways to measure heart rate. The Transmitter will function automatically if it is worn correctly within a meter of the watch. The Transmitter is ergonomically designed to fit comfortably during all types of exercise.
ATTENTION: Anyone beginning an exercise regimen for the first time (especially users of pacemakers or other implanted devices) should consult their physician or health professional before using the heart rate monitor.

Heart Rate Intensity Chart
This is another way to gauge your approximate heart rate zones based on sex, age and weight. Starting with your Max Heart Rate, use the chart to help calculate your zones depending on the intensity of your workout. Note this formula may not work for everyone.
Find your Max Heart Rate Light Intensity (60-70% of Max HR) Exercise in this range at the start of a workout or to recover from a tough workout or race. You should be able to easily maintain a conversation while exercising at this intensity. Determine your Target Heart Rate Zones (Intensities) Moderate Intensity (70-80% of Max HR) Exercise in this range to develop endurance and prepare your muscles to make the transition from aerobic to anaerobic. You should be able to maintain this for a while. You should not be completely breathless and this should not hurt. Heavy Intensity (80-90% of Max HR) Exercise in this range to increase muscle strength and improve your anaerobic threshold. This is uncomfortable. You should be breathing very heavily. You should only be able to sustain this for a brief time. Maximum Intensity (90-100% of Max HR) Exercise in this range to increase mental toughness, Max V02 and tolerance to lactic acid. This is very uncomfortable. You can barely sustain it. You should be completely breathless. Do not exercise at this intensity except on the advice of a trained medical professional.

Troubleshooting

No heart rate displayed on watch: The grooved sensors may not be wet enough. Wet and try again. It is recommended that you wear the Heart Rate Transmitter directly against your skin. If you are wearing the HR Transmitter over clothing, try getting the clothing wet also. The HR Transmitter may not be positioned correctly. Make sure the grooved sensors are flat against the skin. Heart rate reading on watch is erratic or stops: You may need to replace the battery in the HR Transmitter. Sources of electromagnetic fields like appliances, computers and power lines can cause interference. Change your location. This product complies with EN60601-1-2 Watch display is frozen: The display of your watch may "freeze" due to static electricity or recent battery replacement. If this occurs, press and hold all four buttons at the same time. This will erase the data in the memory and allow you to reset the watch to the factory settings.
