•
The UES-40 should only be used under the conditions described in , “Operating environment” in the Appendix. Use under other conditions may impede normal performance and/or result in equipment damage.
•
If the UES-40 is used in conjunction with a non-Olympus electrosurgical unit, keep the electrosurgical accessory away from the target area while the UES-40 is in operation. Do not activate output of both units simultaneously. Patient or operator injury may occur due to the concentration of electric current.
•
When using an electrocardiograph or other physiological monitoring equipment simultaneously with the UES-40 on a patient, any monitoring electrodes should be placed as far away as possible from the electrodes (accessories/hand piece and patient plate) used with the UES-40. If placed too close, high-frequency signals or spark discharge noise from the UES-40 may interfere with the operation of an electrocardiograph or other physiological monitoring equipment. Needle monitoring electrodes should not be used, as they may cause patient burns. Physiological monitoring equipment incorporating high-frequency current limiting devices is recommended.
