Erratic or absent heart rate readings on your Life Fitness Elliptical Trainer can occur for several reasons: * The belt transmitter electrodes may not be wet enough. Wet the belt transmitter electrodes. * The belt transmitter electrodes are not laying flat against the skin. Ensure the belt transmitter electrodes are laying flat against the skin. * The belt transmitter may need cleaning. Wash the belt transmitter with mild soap and water. * The belt transmitter is not within three feet (one meter) of the heart rate receiver. Make sure the chest strap transmitter is within the appropriate range. * The chest strap battery might be depleted. Contact Life Fitness Customer Support Services for instructions on how to have the chest strap replaced.
