Your watch was originally shipped in Power Down Mode which conserves battery life by deactivating the unit when the monitor is not being used for long periods of time. To activate your watch, simply PRESS & HOLD any side button for 3 seconds.

PRESS & HOLD any side button for 3 seconds. This should activate your watch. In the event that does not work, you should replace the battery.

No, you cannot swim with the chest strap on. These items are water resistant but are not designed to be submerged in water. Please remove the strap prior to entering water.

The most widely recognized way to obtain your Maximum Heart Rate is by calculating 220 minus your age for men and 226 minus your age for women. For example, 185 BPM would be considered the maximum for a 35 year old male (220 - 35 = 185).

The "KC" refers to calories and this reflects the total number of calories burned within a given exercise session.

Within the Set Up function (accessed by holding down the Mode/Set button), scroll through until you see "Contrast" on the top. Press the right hand buttons to adjust up or down. The contrast range is from 1(faintest) to 16 (darkest).

Within the Date and Time screen, if the heart icon is showing, the heart rate function is on. To turn off the heart rate function, simply hold the Reset button until the heart icon goes away.

After the Date & Time set up screen you will see a screen that has an "A30" near the center of the screen. This is a default setting and refers to Age 30. To change this age, hold in the Mode button until the "30" starts blinking. Adjust this number up and down using the right hand buttons. Press Mode to confirm. The next input to make is Gender, which is shown on the bottom left hand side of that screen. The default is "M" for Male. To confirm, press Mode. To adjust to Female, press one of the right hand buttons to scroll to "F". Once confirmed, click and hold the Mode button to set and exit.

The "M" you see on the screen along with the word "Gender" refers to "Male". For male users, press Mode/Set button to confirm. For Females, click the right hand side buttons up or down to until you see the letter "F". Press Mode/Set pusher to select.

The "Birth" screen refers to the year you were born. Using the right hand buttons, scroll up and down to adjust the year until you come to you specific birth year. Press Mode/Set pusher to select.

Turns out, your heart beat is a pretty big deal. It's actually one of the most important indicators of overall wellness. And it's one of the most effective elements of any fitness program. Your heart rate not only controls your body but also the efficiency of your exercise. By monitoring your heart rate and aiming to stay within your target ranges, you will get the most out of any physical activity.

Your heart rate is the rate at which your heart contracts and is measured in beats per minute. According to the National Institute of Health, the normal adult resting heart rate falls between 60 to 100 beats per minute. To see how your fitness level is progressing over time, measure and track your resting heart rate (before any physical activity) on a weekly basis. As you become more fit, your resting heart rate will get lower.

By using a HR watch, you can measure and track the intensity of any workout. Here's why this is important. If your goal for example is to burn fat, you should exercise in the Fat Burning Zone which is a range between 55% and 75% of your maximum heart rate where nearly all the calories you burn come from fat. If you're not working too hard or too lightly, a Sportline heart rate watch will know and keep you in the right zone to achieve your fitness goals faster. And it will even calculate how many calories you've burned at the same time.

Sportline Heart Rate Monitors are the easiest to use
While there's no debate that anyone committed to a healthy, fit lifestyle should use a heart rate monitor, it is true that most on the market are extremely expensive, very complicated and requires the use of a constricting, irritating chest strap. Sportline Heart Rate Watches are totally different. They are extremely easy-to-use and One-Touch technology means there's no need for a chest strap. With the touch of a button, the watch will display ECG accurate heart rate readings in seconds.

Sportline Heart Rate Monitors are ECG accurate
Sportline Heart Rate Watches are engineered with highly advanced, patented sensors that ensure readings are accurate as an Electrocardiogram (ECG). These watches are not pulse readers. The internal sensors detect electrical signals emitted from the heart with every beat. Uncomfortable chest straps are no longer needed to deliver ECG level accuracy.

To get the most out of your physical activity- whether it's walking, dancing or aerobics- you need to make sure you are in your target heart rate zone. The target heart rate zone is typically 50-75% of your maximum heart rate. Get to know your target zones (below) and then spend the majority of your exercise time in that zone to make the most of your effort.

Active Zone: 50% - 60% of maximum heart rate
This zone is ideal for fitness beginners on a low to moderate intensity program. Exercising in this zone reduces blood pressure and cholesterol.

Fat Burning Zone: 60% - 75% of maximum heart rate
Exercising in this zone strengthens the cardiovascular system and nearly all the calories burned are from fats.

Endurance Zone: 75% - 85% of maximum heart rate
Reaching this zone requires more intense aerobic activity and is perfect for fitness enthusiasts working to burn maximum calories from fat and carbohydrates. Cardiovascular strengthening, increased metabolism and elevated caloric burn are the primary benefits.

Benefits of Heart Rate Monitors

• Help develop a more effective exercise program
• Alerts you if you are exercising outside (too high or too low) of your target rate
• Instructs you to speed up or slow down the exercise machine to keep you on target
• Since the two main causes of an improper workout are either working too hard or not hard enough, the monitor can help keep you focused

As you get more fit, your heart is able to pump more blood with every beat. As a result, your heart doesn't have to beat as often to get the needed oxygen to your muscles, decreasing resting heart rate and exercise heart rate on all exertion levels.

• A heart rate monitor gives a precise measurement of exercise intensity.
• Training at your own ideal pace is made possible with a heart rate monitor.
• Direct measurement of heart rate during exercise is the most accurate way to gauge performance.
• Progress can be monitored and measured, increasing motivation.
• It maximizes the benefits of exercise in a limited amount of time.
• It introduces objective observation. Are you on the right track? Are you improving?
• It is a tool for regulating frequency and intensity of workouts.
• Because of the immediate feedback it provides, heart rate monitoring is an ideal training partner.

The heart moves blood from the lungs (where the blood picks up oxygen) to the muscles (which burn the oxygen as fuel) and back to the lungs again. The harder the training, the more fuel the muscles need and the harder the heart has to work to pump oxygen-rich blood to the muscles. As you get fitter, your heart is able to pump more blood with every beat. As a result, your heart doesn't have to beat as often to get the needed oxygen to your muscles, decreasing resting heart rate and exercise heart rate on all exertion levels.

Battery replacement will be required from time to time, and should occur when:

1. The display fades in part or completely
2. The functions not activate
3. Backlight System does not operate

To replace the battery of your Sportline heart rate monitor product, we recommend you take it to a watch repair service center or certified jeweler. This will ensure that the water resistance will be retained after battery replacement. For stopwatches and pedometers you can replace on your own by removing the battery cover with a screwdriver, properly discarding the old battery, inserting a new battery, and securely fastening the cover back on.

Under normal conditions you can expect to get approximately 300-400 hours of heart rate transmitter use with a fresh battery. To replace the battery:

• 1. Using a coin, turn the battery door counter clockwise until the door comes free of the strap.
• 2. Take care not to damage the O-ring seal for the battery compartment and carefully remove the old battery.
• 3. Place a new battery in the battery compartment with the positive (+) side toward the battery door. Note: Ensure the new battery is tucked under the gold tab.
• 4. Place the battery door over the opening and tighten it down by using a coin and turning in a clockwise direction.
• 5. If the O-ring has been damaged, replace it before reinstalling the battery door. Most jewelers and watch shops should have replacement O-ring seals.

• Avoid rough usage or severe impacts to the Watch
• Keep the front sensor and back metal plate free from dirt, oils, or other contaminants
• Periodically clean the Watch, using a soft cloth, with a mild soap and water or similar cleaning solution
• Keep the Watch out of extreme heat or cold
• Do not expose the Watch to intense direct sunlight for long periods of time
• Do not expose the Watch to chemicals such as gasoline, alcohol, or solvents
