With your purchase of the Timex®Digital Heart Rate Monitor you have hired a new personal trainer.Your Digital Heart Rate Monitor offers you the ability to track, store, and analyze key indicators of your personal fitness level.

You will find your Digital Heart Rate Monitor to be a user-friendly fitness tool. But, like any new device, you should take the time to familiarize yourself with its components to optimize its usefulness.

So, check out the features and functions of your Digital Heart Rate Monitor to develop a basic understanding of this fitness tool. But most of all, enjoy your new partner on the road to increased fitness!

AA FFiitt HHeeaarrt

Recent fitness findings indicate that anyone can get fit and stay fit without being overzealous. It can be as simple as:

v Exercising 3 to 4 times per week. v Exercising for 30 to 45 minutes during each exercise session. v Exercising at the appropriate heart rate.

Note: Always consult your physician before beginning any exercise program.

Heart rate represents the effects of exercise on all parts of the body.

Selecting the appropriate heart rate zone conditions the heart, lungs, and muscles to perform at optimal levels to get and keep your body in shape.

Once set, your Digital Heart Rate Monitor can automatically show you when you are in the exercise zone you choose and signal you when you are not. It can help keep your body exercising at an intensity level that can help you achieve your desired fitness objectives without over- or underexercising.

WARNING:

This is not a medical device and is not recommended for use by persons with serious heart conditions.

Interference with the radio signal, poor contact between your skin and the Digital Heart Rate Sensor, or other factors may prevent accurate transmission of heart rate data.

You will see the hollow heart icon as the Watch searches for a signal

from the Digital Heart Rate Sensor. You will see the heart icon fill once the Watch has located a signal

from the Digital Heart Rate Sensor. This icon will continue to flash as long as the Watch continually receives a signal from the Digital Heart Rate Sensor.

You will see the stopwatch icon to indicate that the Watch is timing

your activity in Chrono Mode.

You will see the hourglass icon to indicate that the Watch is timing

your activity in Timer Mode. You will see the alarm clock icon to indicate you have set the

alarm to alert you at a designated time. You will see the melody icon to indicate that you have set the

There are five basic heart rate target zones. Simply select a percent of maximum (%MAX) heart rate that matches your zone and the fitness goal you want to achieve during a particular exercise.

% MAX Goal Benefit

ZONE

50% to 60% Light exercise Maintain a healthy heart and get fit

60% to 70% Weight management Lose weight and burn fat

70% to 80% Aerobic base building

80% to 90% Optimal conditioning Sustain excellent fitness condition

90% to

100%

Before you can set your target zone, you first need to determine your maximum heart rate. You can use many methods to estimate your maximum heart rate. The booklet Heart Zones in your Personal Heart Rate Monitor packaging (U.S. customers only) provides excellent procedures and Timex recommends you use one of these methodologies.

Elite athletic training Achieve superb athletic condition

Increase stamina and aerobic endurance

Tools For Success included

However, if you cannot use any of the procedures described in Heart Zones® Tools for Success (U.S. customers only), you might consider using

an age-based method.

Begin with the number 220 and then subtract your age. For instance, a 35 year old would begin with 220 and subtract 35 (her age), which gives an estimated maximum heart rate of 185. Once you know your maximum heart rate, you can set the zones described in the table on the previous page.

Once you have determined your fitness goal and maximum heart rate, Timex recommends you input this information into the HRM SETUP Mode. This will allow you to tailor your Digital Heart Rate Monitor to your personal parameters. For information on HRM Setup Mode, refer to pages 25 to 30.

Heart rate recovery provides an indicator of fitness and training level. As you become more fit, your heart rate should return more quickly to a lower heart rate value at the end of your activity, indicating a higher level of cardiovascular fitness.

A slower recovery rate might also indicate a need to take a break from training due to fatigue, illness, or other factors.

Your recovery rate represents the change in your heart rate over a period of time. Your Digital Heart Rate Monitor records the change in your heart rate for either a 1- or 2-minute period.

While running the chronograph, the recovery heart rate timer will begin automatically after pressing STOP/SET/RESET if the Watch is receiving data from the Digital Heart Rate Sensor. You can also manually initiate a recovery heart rate after stopping the chronograph by following these steps.

1. Press MODE until RECOVER appears.

NOTE: From this display, you set the duration of the automatic recovery heart rate recorded at the end of a chronograph session.

2. Press STOP/SET/RESET to toggle between a 1- or a 2-minute recovery time.

3. Press START/SPLIT. The top line of the Watch display will show the heart rate at the beginning of the recovery period followed by your current heart rate. The bottom line will show the time remaining in your recovery countdown.

NOTE: The Watch cannot record a recovery unless it is receiving by valid heart rate data from the Digital Heart Rate Sensor. Without a current heart rate, the display will read NO HRM DATA at the end of the recovery period. If the starting heart rate is lower than the ending heart rate, the display will read NO REC.

4. After a 1- or 2-minute countdown, the Watch will beep indicating the end of the recovery period. The Watch will capture your heart rate a second time, subtract the second value from the first value and display the difference as the recovery.

5. You can continue to initiate a 1- or 2-minute recovery period by repeating step 3.

Digital Heart Rate Sensor Battery

If your heart rate readings become erratic or stop, you may need to replace the battery on your Digital Heart Rate Sensor.You can change the battery yourself without any special tools.

This product uses a CR2032 lithium battery for the Digital Heart Rate Monitor. To change the battery:

1. Open the Sensor battery lid with a coin, turning the coin counterclockwise.

2. Replace the battery with a new CR2032, 3V lithium battery with (+) facing you, taking care not to touch the two contacts and discharge the battery.

3. When you have finished inserting the battery, press the reset button (located in the lower left corner) with a toothpick or straightened paper clip and close the lid with a coin -- screwing in a clockwise direction.

To test the new battery after you have inserted it:

1. Move away from any possible sources of electrical or radio interference.

2. Wet the Digital Heart Rate Sensor pads and securely fasten the chest strap below your sternum.

3. While wearing the Watch, press the HEART RATE button. A set of three dashes (- - -) and the flashing heart rate icon will appear on the display.

4. If you do not see a flashing heart icon on your Watch, reinstall the sensor battery.

NOTE: It is not necessary for a heart rate value to appear on the display during this test.

Watch Battery Replacement

When the battery of the Watch is running low, the display or INDIGLO night-light will dim. This Watch uses a CR2032 lithium battery.

To avoid the possibility of permanently damaging the Watch, TIMEX STRONGLY RECOMMENDS TAKING YOUR MONITOR TO A LOCAL RETAILER OR JEWELER TO HAVE THE BATTERY REPLACED.
