10-8-3 Probe Fails
Test the probe in another connector to isolate if the fault lies with 
the probe or the Ultrasound system. Or Change another probe 
to confirm if the fail is caused by console.
NOTE:  Each probe will have some amount of leakage, dependent on its 
design. Small variations in probe leakage currents are normal 
from probe to probe. Other variations will result from differences 
in line voltage and test lead placement. The maximum allowable 
leakage current for body surface contact probe differs from 
inter-cavity probe. Be sure to enter the correct probe type in the 
appropriate space on the check list.
If excessive leakage current is slot dependent, inspect the 
system connector for bent pins, poor connections, and ground 
continuity.
If the problem remains with the probe, replace the probe.
10-8-4 Peripheral Fails
Tighten all grounds. Ensure star washers are under all ground 
studs.
Inspect wiring for bad crimps, poor connections, or damage.
10-8-5 Still Fails
If all else fails, begin isolation by removing the probes, external 
peripherals, then the on board ones, one at a time while 
monitoring the leakage current measurement.
10-8-6 New Unit
If the leakage current measurement tests fail on a new 
Ultrasound system and if situation can not be corrected, submit 
a Safety Failure Report to document the Ultrasound system 
problem. Remove Ultrasound system from operation.
10-8-7 ECG Fails
Inspect cables for damage or poor connections.
