Mode of Operation
NON-CONTINUOUS - The Uscan enforces non-continuous scanning to maintain safe user enclosure contact
temperatures. Non-continuous scanning is enforced as the enclosure temperature approaches 48°C.
Warning
 After storage at extreme temperatures, check the transducer surface temperature before applying to a
patient. A cold or hot surface may burn a patient.
Caution
 Only operate, charge and store Uscan within the approved environmental parameters.

Measurement accuracy

Measurements reflect a physical property such as area or volume for interpretation by a clinician. They do not
account for variations in acoustic speed of the body, which can vary significantly.
