If you have purchased a new transmitter as an accessory, it will have to be introduced to the training
computer. For further information, see Teach a New Transmitter.
If the transmitter you are using is included in the product set, and the text appears on the display, the
training computer may be detecting the signal of another transmitter. In that case, make sure you are
wearing your own transmitter, that the electrodes are moistened, and that the transmitter belt has not
loosened. If the message still appears, the battery of your transmitter is empty. For further information,
see Care and Maintenance.
...S sensor calibration failed is displayed?*
Calibration did not succeed and you need to re-calibrate. Calibration fails if you move during the
process. Once you reach lap distance, stop running and stand still for calibration. The range of the
calibration factor during manual calibration is 0.500-1.500. If you have defined the calibration factor
below or above these values, calibration fails.
…Teach new sensor? is displayed?
If you have purchased a new sensor as an accessory, it will have to be introduced to the training
computer. For further information, see Feature Settings.
If the sensor you are using is included in the product set, and the text appears on the display, the
training computer may be detecting the signal of another sensor. In that case, make sure you are
wearing your own sensor. If the message still appears, the sensor battery is empty. For further
information, see Care and Maintenance.
...the altitude keeps changing even if I am not moving?
The training 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 training computer to a Polar Service
Center.
....Memory low is displayed?
Memory low is displayed when there is approximately 1 hour memory left. To maximize the remaining
memory capacity, select the longest Recording Rate (60 sec) from Settings > Features > Rec.rate. Once
the memory has been depleted Memory full is displayed. To free memory transfer the exercises to Polar
Pro Trainer 5 software and delete them from the wrist unit memory.
*Optional s3 stride sensor W.I.N.D. required.
