My polar heart rate monitor counts the heart beets for quite a while before it gives me the heart rate as a number it may be up to one hour before it gives me a mumber.

I think the image below will help you.

First you need to understand that the Polar system is a medical grade device and it is calculating calories based on specific information that you have inputed and heart rate data from your heart.

Most treadmills and other exercise machines use a much simpler counter that is height and weight based to calculate calories and are generally over generous with their numbers.

Depending on the blood pressure machine you are using, the pulse (not heart rate) is coming through the brachial artery, again not quite as accurate as measuring r-r variance from your heart. There is a ton of literature you can read if you are into the accurateness of the system, but I will sum up with saying that you actual calorie expenditure will be closer on the Polar than on most other devices outside of a hospital. As too the heart rate this is also true, so more likely you are getting inaccurate numbers from the other devices.

If you want pinpoint accuracy then you will need to use the Polar RS800 or S810 devices that measure and display true R-R.

I just checked the polar web site and found this. I was given the same number by another retailer. MONTRE SERVICE MONTPARNASSE 33 22 RUE DU DEPART - CC MONTPARN 75015 PARIS tel: 01 43 35 32 93 fax: 01 43 35 32 93

Honestly, I would contact Polar at this link:

Good luck.

The only alarms available to use for that watch is your heart rate for exercise and a daily alarm. Unfortunately it does not have the hourly alarm feature. I wish it did I am a personal trainer and hourly chimes would help to keep me on time but my rs200 doesn't have the feature either. Sorry :)

You do not have the right model number. For some reason, Polar puts the CE0537 in big numbers on the back of the case. The real model number on my unit was in very light engraving right above the words "Polar Electro" on the back of the case. Looks like they have an engraving problem where both the model and serial number are very hard to read. If it helps, my model was S120 and I found the manual quickly on the polar site. The polar site also has the location of model numbers in their FAQ area.
