The optional Heat Rate Chest Strap is required when using a Lifecycle bike which is
equipped with Polar compatible telemetry heart rate monitoring technology.
The heart rate reading is erratic or absent entirely.
l
Repeat the electrode wetting procedure (see How to Use the Optional Heart Rate Chest
Strap). The electrodes must be wet to pick up and transmit accurate heart rate readings.
l
Make sure the electrodes are flat against the skin.
l
Wash the belt transmitter regularly with mild soap and water.
l
Make sure the chest strap transmitter is within three feet (one meter) of the
heart rate receiver.
l
The estimated battery life of the chest strap transmitter is 2500 hours of use. If the
chest strap transmitter battery is depleted, contact Life Fitness Customer Support
Services for instructions on how to have your chest strap replaced. (See “How to
Obtain Product Service” for locations.)
The heart rate reading is erratic or extremely high (above 200).
l
When exercising with the heart rate chest strap, it may come within range of
electromagnetic signals strong enough to cause abnormally elevated heart rate
readings. Possible sources of such signals include television sets and/or antennas,
computers, cars, high voltage power lines and motor driven exercise equipment.
Another heart rate transmitter within three feet (one meter) may also cause abnormal
heart rate readings.
5.3 Troubleshooting the Optional Heart Rate Chest Strap
NOTE: There is a very small – less than one percent – portion of the general
population whose heart rates can not be detected by heart rate
monitors, including Electrocardiograph. This phenomenon is called
biopotential and is extremely rare.
