RS400 Crosstalk. A heart rate symbol without a frame indicates non-coded heart rate transmission. When in non-coded mode, the running computer picks up transmitter signals within 1 m / 3 ft. Simultaneous non-coded signals from more than one transmitter can cause an incorrect reading.

If another person with a running computer or a heart rate monitor is causing interference, move away from that person and continue your exercise normally.

Alternatively, to avoid other people’s heart rate signals:

1.Take the transmitter off your chest for 30 seconds. Move away from the other device.

2.Put the transmitter back on and bring the running computer up to your chest near the transmitter’s Polar logo. The running computer will start searching for a heart rate signal again. Continue your exercise normally.

Using RS400 Running Computer in Water. The

running computer may be worn when swimming. It is not, however, a diving instrument. To maintain water resistance, do not press the buttons of the running computer under water. When measuring heart rate in water, you may experience interference for the following reasons:

•Pool water with a high chlorine content, and seawater, are very conductive. The electrodes of a transmitter may short-circuit, preventing ECG signals from being detected by the transmitter.

•Jumping into water or a strenuous muscle movement during competitive swimming may shift the transmitter to a location on the body where ECG signals cannot be picked up.

•The ECG signal strength is individual and may vary depending on the individual’s tissue composition. Problems occur more frequently when measuring heart rate in water.

The S1 foot pod can be used in any wet running environment, including rain, but it is not intended for underwater use.
