the cycling computer may be detecting the signal of another heart rate sensor. In that case, make sure you
are wearing your own heart rate sensor, that the electrodes are moistened, and that the heart rate sensor
strap has not loosened. If the message still appears, the battery of your heart rate sensor is empty. For

The cycling computer converts measured air pressure into an altitude reading. This is why changes in the
weather may cause changes in altitude readings.
…the altitude readings are inaccurate?
Your altimeter may show faulty altitude if it is exposed to external interference like strong wind or air
conditioning. In this case, try to calibrate the altimeter. If the readings are constantly inaccurate, dirt may
be blocking the air pressure channels. In this case, send the cycling computer to a Polar Service Center.
...Memory low is displayed?
Memory low is displayed when there is approximately one hour of memory space left. Once the memory
has been depleted Memory full is displayed. To free memory space, transfer exercise data to Polar
