Determining your heart rate

In addition to many other useful features, your Watch uses technology that helps you track detailed information about your heart rate. But, before you can track this information, you first need to determine your maximum heart rate. You can use many methods to estimate your maximum heart rate.

The booklet Heart Zones¨ Tools For Success included in your Watch packaging provides excellent procedures and Timex recommends you use one of these methodologies. However, if you cannot use any of the procedures described in Heart Zones¨ Tools for Success, you might consider using the widely used, though highly debated, 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 (the personÕs age) which gives an estimated maximum heart rate of 185.

Setting your Watch for first use

Once you determine your heart rate, set the following parameters prior to using your Watch:

1.Set the time of day. For detailed information on Time of Day Mode, including instructions for setting time of day, refer to page 15 of this manual.

2.Enter your maximum heart rate. In Configure Mode, select HRM SETTINGS and then MAX HR. Your maximum heart rate setting determines your five preset heart rate target zones. For more information on Configure Mode, refer to page 36.

3.Select your desired heart rate display units. In Configure Mode, select HRM SETTINGS and then HRM DISPLAY. Your Watch gives you the option to view your heart rate in beats per minute (BPM) or as a percentage of your maximum heart rate (PERCENT). For more information on Configure Mode, refer to page 36.
