Performance considerations

Crosstalk
The SenseWear Armband uses a non-coded mode of operation and can pick up RF (radio frequency)
transmitter signals within 3ft. (1m). Therefore make sure no other transmitter is within that range.
Non-coded signals from more than one transmitter picked up simultaneously can cause incorrect
data collection.
Interference: Other products affecting the SenseWear Armband
As with many electronic devices, because of the proliferation of radio-frequency transmitting
equipment and other sources of electrical noise (e.g., cellular phones, mobile two-way radios,
electrical appliances, electronic exercise equipment), it is possible that high levels of such
interference due to close proximity or strength of a source may result in disruption of performance
of this device.
