Checks: Perform the daily checks to assure the safety of the FX Perform the periodical checks every three to four months to assure the safety of the FX Perform the periodical checks to be performed by a specialist every 12 months to assure the safety of the FX x 13 Equipment Symbols The following symbols are printed on the Cardimax FX Attention: Read the Operation Manual.

Operation is bypassed if the electrodes on the patient cable come into contact with any other metal object or other electrically conductive objects, including the operator s hands. When such contacts occur, there is a risk of electric shock, regardless of whether or not the objects are grounded. All ECG wires (patient connections), connectors, and amplifiers are electronically isolated from the rest of the device and from ground. This isolation restricts the current that can pass through a patient to less than 10 microamperes. If the power supply cords of several different units are connected together in a multiple outlet tap, an increase in chassis leakage current can create a potential hazard. When a cardiac pacemaker or other electrical stimulator is connected to the patient, it increases the risk of a potential hazard. Pay particular attention to safety measures to record ECG in such conditions. Appropriate measures must be taken to assure that the chassis leakage current is at a safe level. The FX-7202 is Type CF equipment. It must not, however, be placed in direct contact with the area of the heart. Be sure to connect the power supply cord to a hospital-grade wall AC outlet.
