Safety test overview  (continued)
Prior to initiating any electrical test, the Ultrasound system must 
be visually inspected. Perform the following visual checks:
•  Check for missing or loose enclosure covers that could 
allow access to internal live parts.
•  Examine the mains cord, mains plug and appliance inlet for 
damaged insulation and adequacy of strain relief and cable 
clamps.
•  Locate and examine all associated probes. Inspect the 
cables and strain relief at each end. Inspect the transducer 
enclosure and lens for cracks, holes and similar defects.
