Alerts

This watch enables you to select a target HR zone according to your fitness goals. By setting the target HR zone and personal data, the watch can monitor how well you do. The watch will send out visual and audible alerts if you are pushing yourself too hard or need to put more effort in.

For details of HR zones, refer to “Understanding heart rate” section in this manual.

If alert has been enabled and heart rate zone has been set:

ICON	BEEP(S)	DESCRIPTION
/ ABOVE ZONE!	2	You have gone above your upper HR limit
/ BELOW ZONE!	1	You have gone below your lower HR limit

Remember, these alerts are based on a calculation of your maximum heart rate and the HR zone you selected. As such, it is an estimation and is only for guidance. If you feel you are working too hard, most likely you are. Adjust the HR zone to one that works for you.

Understanding Heart rate

Heart Rate zones and exercise

Heart rate is an indicator of the intensity of the exercise on your body. It is a useful tool for determining how effective a work-out is.

This watch uses an estimation of your maximum heart rate (220 - age = MHR) to arrive at 5 HR zone settings specific to you.

HR Zone	Corresponding	Description / benefit derived	Examples

		and performance. May increase chance
		of injury and soreness.

*The upper and lower heart rate limits are calculated by multiplying your maximum heart rate (MHR) by the percentages.

It is important to pace yourself, especially if you haven’t exercised for a while. Start off slow, aiming for the lowest range (50%-60%). As you become more comfortable, challenge yourself by increasing in speed and duration.

To benefit most from your work-out, determine your fitness goal and exercise at a proper intensity. The most common zone range is from 50% to 80% of your maximum heart rate. This is where you achieve cardiovascular benefits, burn fat and become more fit.

Remember, if you rush in too quickly and push your body too hard before it’s ready, it can be counterproductive. You can hurt your muscles / tendons and may even result in injury and be a real step back from your goal.

IMPORTANT Always warm up before exercise and select the HR zone setting that best suits your physique. Exercise regularly, 20 to 30 minutes per session, three to four times a week for a healthier cardiovascular system.

WARNING Determining a suitable exercise intensity is a critical step in the process towards an efficient and safe training program. Please consult your doctor or health professional to help you determine exercise frequency and duration appropriate for your age, condition and specific goals.
