PRECAUTIONS

The Polar M430 is designed to tell your activity and measure heart rate, speed, distance and running
cadence. 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 equip-
ment, 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.
