precision.
INTERFERENCE DURING TRAINING
Electromagnetic Interference and Training Equipment
Disturbance may occur near electrical devices. Also WLAN base stations may cause interference when training with the
training device. To avoid erratic reading or misbehavior, move away from possible sources of disturbance.
Training equipment with electronic or electrical components such as LED displays, motors and electrical brakes may
cause interfering stray signals. To solve these problems, try the following:
1. Remove the heart rate sensor strap from your chest and use the training equipment as you would normally.
2. Move the training device around until you find an area in which it displays no stray reading or does not flash the
heart symbol. Interference is often worst directly in front of the display panel of the equipment, while the left or
right side of the display is relatively free of disturbance.
3. Put the heart rate sensor strap back on your chest and keep the training device in this interference-free area as
much as possible.
If the training device still does not work with the training equipment, it may be electrically too noisy for wireless heart
rate measurement.
HEALTH AND TRAINING
Training may include some risk. Before beginning a regular training program, it is recommended that you answer the
following questions concerning your health status. If you answer yes to any of these questions, we recommend that
you consult a doctor before starting any training program.
Have you been physically inactive for the past 5 years?
l
Do you have high blood pressure or high blood cholesterol?
l
Are you taking any blood pressure or heart medication?
l
Do you have a history of breathing problems?
l
Do you have symptoms of any disease?
l
Are you recovering from a serious illness or medical treatment?
l
Do you use a pacemaker or other implanted electronic device?
l
Do you smoke?
l
Are you pregnant?

Note that in addition to training intensity, medications for heart conditions, blood pressure, psychological conditions,
asthma, breathing, etc., as well as some energy drinks, alcohol, and nicotine may also affect heart rate.
It is important to be sensitive to your body's responses during training. If you feel unexpected pain or excessive
fatigue when training, it is recommended that you stop the training or continue at a lighter intensity.
Note! If you are using a pacemaker or other implanted electronic device, you can use Polar products. In theory
interference to pacemaker caused by Polar products should not be possible. In practice no reports exist to suggest
anyone ever having experienced interference. We cannot however issue an official guarantee on our products'
suitability with all pacemakers or other implanted devices due to the variety of devices available. If you have any doubts,
or if you experience any unusual sensations while using Polar products, please consult your physician or contact the
implanted electronic device manufacturer to determine safety in your case.
If you are allergic to any substance that comes into contact with your skin or if you suspect an allergic reaction due to
using the product, check the listed materials in
the product and consult your physician. Also inform Polar Customer Care about your skin reaction. To avoid any skin
reaction to the heart rate sensor, wear it over a shirt, but moisten the shirt well under the electrodes to ensure flawless
operation.
