(Reference section 4.6 page 44)
7. If the unit is inflating/deflating properly however there is no reading given, change out the main
PCB. (Reference section 4.6 page 44)
8. FOR THE SPO2 OPTION: Connect the patient simulator to the unit SpO2 connection by the
Nellcor SpO2 cable. Confirm readings equal to the specifications called out in the Repair Test

key (5200-25), remove the probe and Confirm reading meets specifications called out on the Repair
Test Specification document. If there is no reading at this point, change the temperature connector
PCB and cable to the main PCB. (Reference section 4.2 page 40)
