Using the G1 Sensor in Water
Polar G1 sensor is water resistant. It can be safely worn
in the rain or while crossing rivers or canoeing. The
GPS reception system does not function under water.
Troubleshooting
• If speed or distance readings are irregular or show
zero, something in your surroundings may be
blocking satellite signal reception (e.g. a building or
terrain). If the sensor cannot locate the satellite
signals, it will not be able to calculate its location.
Speed values may therefore show zero. Distance is
measured between the last location before the
shadow area, and the first location after the shadow
area in a straight line, i.e. curves are not counted.
• Strong electromagnetic signals can cause erratic
readings. Electromagnetic disturbances may occur
near high-voltage power lines, traffic lights,
overhead lines of electric railways, electric bus lines
or trams, televisions, car motors, bike computers,
some motor driven training equipment, cellular
