Danger of explosion if the battery is replaced with wrong type.
PRECAUTIONS
The Polar V800 training device shows your performance indicators. The training device is designed to indicate
the level of physiological strain and recovery during and after an exercise session. It measures heart rate,
speed and distance. It also measures running cadence when used with Polar stride sensor Bluetooth® Smart
and cycling cadence when used with a Polar cadence sensor Bluetooth® Smart . No other use is intended or
implied.
The training device should not be used for obtaining environmental measurements that require professional or
industrial 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 nor-
mally.
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. For further information, www.polar.com/support.
Parts of V800 are magnetic. It may attract metallic materials and it's magnetic field may interfere with a
compass. To avoid interference, it is recommended to wear your compass on one arm (at the level of your
chest) and your V800 on the other arm's wrist. Do not place credit cards or other magnetic storage media near
V800, because information stored on them may be erased.
MINIMIZING RISKS WHEN 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.
