IMPORTANT NOTE ON WIRELESS MONITORS

Because they are radio-type devices, wireless monitors can be affected by some electrical equipment generating radio or magnetic interference in much the same way as your radio and TV set can be. We have found that some of the wireless units will not work while riding in a car, within one-foot of a TV set or computer monitor, on some Lifecycles and Liferowers, on some treadmills, some Stairmasters, and some other exercise equipment using electric motors or video screens. In addition, if users are very close to one another, they can interfere with each other; even between brands, since all operate on the same frequency. The Polar S Series has a special coded transmission system which reduces interference from equipment etc. and other monitors including all standard Polar and Polar models with coded transmitter. The Acumens have an interference resistant transmitter which reduces interference from other makes of monitors and exercise equipment. However Acumen monitors can interfere with each other. Timex monitors use a digital FM transmission and are not affected by interference from equipment.

ACCURACY

We get many questions on accuracy. We have found that most of the heart rate monitors are reasonably accurate, with the exceptions noted above, if the limitations of each type are accounted for and they are used in the manner intended for each type. The wireless EKG types have the fewest limitations and thus, will work best under the widest range of conditions and exercise. There are some situations, such as while using a rowing machine, that only an EKG type of monitor will work properly. We also find there are a few individuals for whom one type of heart rate monitor will not work well, but another type of monitor would. We are always glad to let these people try out different types, if the type they first selected, does not work on them.

RELIABILITY

We also get questions on reliability. Like all electronic products, there are always the possibilities of a defect. We have found the defect rate on these monitors, range from 1/2 to 1%, except for the few exceptions noted above. This is typical of all small electronic products. Usually if a problem occurs, it will occur within the first 30 days. If this happens, we exchange the defective component for a new one immediately. Usually if a monitor proves good for the first 30 days, then it will give many years of trouble free service. All the above units are guaranteed for 1 year for the watch units and 2 years for the transmitter. Of course, like any electronic product, any of the units can be damaged by abuse, such as dropping it on a hard surface, crushing, overheating, getting chewed by the dog, etc. Any damage caused by these kinds of events is not covered by warranty.

WATER RESISTANCE

Most monitors are now water resistant. The ones that are not, are the infrared monitors, and all of the Biosig Insta-Pulse models (except the 105 WP). These models vary from somewhat water resistant to almost completely water resistant, and will tolerate small amounts. There is one precaution necessary, however, on the water resistant models. The control buttons on the face and sides are water resistant. However, on some models, the seal can be momentarily broken when a button is pushed. So, if the watch is underwater, or if there is water or sweat on your finger tip or on a button when it is pushed, the water or sweat can be pushed through the sides of the button and right into the watch, often damaging it. So, if a button is pushed, it is important to be sure your finger and the button are dry.

MAINTENANCE

With respect to maintenance, all heart rate monitors require batteries from time to time. The wireless units use long-life Lithium batteries, which will last 1 to 3 years in the watches. The integral type transmitters now used on all wireless monitors are guaranteed for 2 years and typically last 3 to 5 years with average use. All the sensors used with the other types of monitors, (ear lobe, finger, and chest straps) will deteriorate with time, and will have to be replaced. The cost for these components is very modest, and we keep them all in stock for immediate shipment. Typical life of these parts, with average use, is nine months to one year. Replacement costs for the most commonly required components are shown in the Creative Health Products Discount Price List.
