...Check Sensor message appears on the display?

1.Check that you have the right speed settings turned on from the wrist unit.

2.Make sure that the foot pod is turned on.

3.If there is no light on the foot pod you may have exceeded 20 running hours and the battery of the foot pod needs to be replaced. Check the Easy start section of this manual for detailed instructions on changing the battery.

4.If you keep the wrist unit in front of you for longer than 15 seconds the speed and distance measurements stop. You need to reactivate the measurements by moving your hand.

5.If you are running on a treadmill and have attached the wrist unit to a crossbar in front of you, try moving the wrist unit sideways.

Supress the Check Sensor message for the rest of the exercise by pressing and holding the light button when the message is on the display.

...I have replaced the battery of the foot pod, but the sensor still does not work?

Please contact your local Polar distributor. Check www.polar.fi for the contact information of the local Polar distributors.

...the speed reading is 00 or there is no speed reading on the display while cycling?

1.Check the correct position and distance of the speed sensor with the spoke magnet and the wrist unit.

2.Check that you have set bike 1 or 2 on.

3.If the 00 reading appears irregularly, this may be due to temporary electromagnetic interference in your current surroundings.

4.If the 00 reading is constant, you may have exceeded 2500 riding hours and the battery of the speed sensor needs to be replaced.

5.If you are using the wireless Polar Speed Sensor, check that Power is turned off in the Options mode.
