    1 PRECAUTIONS  The pedar-x system should not be used in extremely high temperatures or high humidity. The recommended operating conditions are 0-40C (32-100F) and 20-80% humidity.  The flexible insole sensors should be handled with care. Pressure ranges outside the designated loading should be avoided as well as use of sharp objects on the sensing device.
