POLAR FT4 - Manual (Page 13)

reaction due to using the product, check the listed materials in Technical Specifications. To avoid any
skin reaction to the transmitter, wear it over a shirt. Moisten the shirt well under the electrodes to ensure
flawless operation. If you use insect repellent on your skin, make sure that it does not come into contact
with the training computer or the transmitter.
Exercise equipment with electronic components may cause interfering stray signals.
To tackle these problems, try the following:
1. Remove the transmitter from your chest and use the exercise equipment as you would normally.
2. Move the training computer around until you find an area in which it displays no stray reading or does not flash the heart
symbol. Interference is often worst right 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 transmitter back on your chest and keep the training computer in this interference-free area as much as possible.
If the Polar FT4 still does not work, the piece of equipment may be electrically too noisy for wireless heart
rate measurement.
Water Resistance of the Polar FT4 Training Computer
Polar FT4 may be worn when swimming. To maintain water resistance, do not press buttons under water.
For more information, visit http://www.polar.fi/support. Water resistance of Polar products is tested
according to International Standard ISO 2281. Products are divided into three categories according to
their water resistance. Check the back of your Polar product for the water resistance category, and
compare it to the chart below. Please note that these definitions do not necessarily apply to products of
other manufacturers.

Troubleshooting
If you don't know where you are in the menu, press and hold BACK until the time of day is displayed.
If there are no reactions to any buttons or the FT4 displays unusual readings, reset the training computer
by pressing four buttons (UP, DOWN, BACK and LIGHT) simultaneously for four seconds. The display will
go blank for a moment. Press OK and
Please enter basic settings will shortly be displayed. Enter time
and date. With long press BACK the display returns to time of day view. All other settings except time and
date will be saved.
If the heart rate reading becomes erratic, extremely high or shows nil (00), make sure that there are no
other heart rate transmitters within 1 m/3 ft and that the transmitter strap/the textile electrodes fit snugly
and are moistened, clean and undamaged.
If the heart rate measurement does not work with the sports apparel, try using the strap. If it works, the
problem is most probably in the apparel. Check that the electrode areas of the apparel are clean. Before
washing the apparel, check the washing instructions. If the heart rate measurement still does not work,
please contact the apparel retailer/manufacturer.
Strong electromagnetic signals can cause erratic readings. Electromagnetic disturbances may occur near
high-voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams,
televisions, car motors, bike computers, some motor driven training equipment, cellular phones, or at
electric security gates. To avoid erratic readings, move away from possible sources of disturbance.
