6.1 Maintenance Inspection
(1) Visual Inspection
Please perform the following check before you use FTS-3:
Check the base station and transducers 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 system functions properly.
If any damage is detected, replace the damage part(s) or contact EDAN immediately.
(2) Routine Inspection
The overall check of FTS-3, 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.
