5.1 Maintenance Inspection
(1) Visual Inspection
Check the monitor and accessories to see if there is any visible damage that may affect
patient’s safety.
Check all the outer cables, power socket and power cables.
Check if the monitor functions properly.
If any damage is detected, replace the damage part(s) or contact EDAN immediately.
(2) Routine Inspection
The overall check of the monitor, including the safety check and functional check, should be
performed by qualified personnel every 6 to 12 months, and each time after service.
The equipment should undergo periodic safety test to insure proper patient isolation from live
parts. This should include leakage current measurement and insulation testing. The recommended
testing interval is once a year or as specified in the institution’s test and inspection protocol.
