1.5 General Warnings
•
This equipment is to be used only as described in this manual.
Failure to do so may result in damage to the device.
•
The CTU must not be used on equipment while connected to
a patient.
•
Do not use the Calibration Test Unit in the presence of flammable
agents because an explosion or fire may result.
•
Anyone performing the procedures must be appropriately qualified.
•
Carefully observe the Calibration Test unit for fluid leaks before and
