Troubleshooting
6.3.1
The troubleshooting procedures in this manual instruct the
technician to isolate the failure down to the sub-assembly
level. The intention is to have the Unit Under Test (UUT)
repaired with minimal steps. A safety analyzer or Hi-
pot/Current Leakage test unit will be needed in the event the
Docking Station is disassembled. The Masimo SET Tester
will be needed to perform the Performance Verification in
Section 5 upon completion of repairs.
