IMPORTANT:
• Read this instruction manual thoroughly before operating the unit.
• This unit is not a medical device. It is meant to provide a general guide assisting you during workout. Please consult your doctor before beginning any exercise program.

While this watch works like a standard sports watch, it includes an advanced heart rate sensing technology - S-Pulse™ - that provides easy and accurate contact heart rate readings.

S-Pulse™ is a patented heart rate sensing technology that measures the electrical signals on your skin – in the same manner that an EKG or electrocardiogram does.

While the Sportline Solo 900 Heart Rate Watch attaches to your wrist like other watch products, it does not measure or sense your pulse at your wrist. It instead uses S-Pulse™ technology to sense your heart rate by measuring your EKG signal.



How to Measure Your Heart Rate
To get your heart rate reading, just follow these simple steps:
1. Place the Sportline Solo 900 Heart Rate
Watch on your wrist, adjusting for a snug, comfortable fit.

2. Place your finger on the Sportline Solo 900 Heart Rate Watch’s sensor, as shown, and press gently for 3-8 seconds.
Be sure to activate the Heart Rate mode by pressing the bottom metal sensor so that the display flashes. It is best to use the flat ‘pads’ of your finger, and not the fingertips.

3. A ‘beep’ will sound and your heart rate will be displayed. It’s that easy!

Because the Sportline Solo 900 Heart Rate Watch is a sensitive monitoring device that reads your EKG signals, reading times will vary. If you don’t get a reading in 3-8 seconds, wait a couple of minutes and try again. This gives the Sportline Solo 900 Heart Rate Watch a chance to settle in and pick up your electrical signals.

Your heart rate will remain displayed once measured, and will remain displayed for 7 seconds after you release the sensor button.

• The Sportline Solo 900 Heart Rate Watch must be attached to your wrist in order for the Heart Rate Measure function to work.

• Proper finger pad contact is very important and affects the heart rate reading time.

• For those users with dry skin, thick or calloused finger, low heart rate signal strength (EKG strength), minimal padding on your finger, or users located in dry environments, please see our Helpful Hints section.

• The Heart Rate Measure function is not intended for use or operation in or under water.



How to Calculate Your Maximum Heart Rate
• Deduct your age from 220 (220 - your age = your maximum heart rate)

• Example of Relative Heart Rate
- Tom is 30 years old
- His heart rate measured at 132
- Maximum heart rate is 220 - 30 = 190 bpm
- 132/190 = 70% Relative Heart Rate



If you are having difficulty measuring your heart rate, you may want to try the following steps. Try each of these in order until you successfully measure your heart rate:

1. Make sure the Sportline Solo 900 Heart Rate Watch is snugly strapped to your wrist. A loose fit makes it more difficult to properly measure your heart rate.

2. When pressing on the sensor, make sure that you are using the soft, flat pads of your finger, not the tip of your finger.

3. Press gently with enough pressure to activate the heart rate measure mode. Muscle ‘noise’ from pressing too hard can make it difficult to measure your heart rate.

4. Make sure that the metal back of the Heart Rate Watch is laying flat on your skin.

5. Make sure your wrist and finger are clean and free from dirt, oils, or lotions.

6. Stay still, and relax your arms on a stable surface while taking your heart rate.

7. Clean the front sensor and back metal plate with a mild soap and water or similar cleaning solution.

8. Moisten with water the pads of the finger that you are using to contact the sensor on the face of the watch.

9. Moisten with water the surface between the back metal plate of the watch and the skin on your wrist.

How the Sportline Solo 900 Heart Rate Watch Works
It is useful to understand the basics of how the watch’s S-Pulse™ sensing technology works – as it will perform differently on people of different age, skin type, body type, EKG or electro-cardiogram signal strength, among others.

The S-Pulse™ technology measures the electronic signals that pass through your body – that result from the beating of your heart. Many are familiar with the EKG waveform – from either personal experiences while at the hospital, or from popular television medical shows. It is this same signal that passes through your body that S-Pulse™ measures.

This measurement is obtained by the Watch’s 2 metal sensors. The back metal plate of the Watch wrist is actually a primary sensor that measures these electronic signals off your arm. The ‘EKG’ measurement is done when you place your finger from one hand on the top sensor on the Watch that is attached to your opposite arm. This creates a loop across your body that the Watch can now read.

The Sportline Solo 900 Heart Rate Watch must be attached to your wrist in order for the Heart Rate Measure function to work.
