If the troubleshooting procedure requires you to disassemble the monitor or transducers, be certain to
follow the disassembly and reassembly procedures given in "Repair and Disassembly" on page 139.

Who Should Perform Repairs

Only qualified and authorized service personnel should open the monitor housing, remove, and
replace components, or make adjustments. If your medical facility does not have qualified and
authorized service personnel, contact Philips' Response Center or your local Philips representative.
WARNING
High Voltage - Voltages dangerous to life are present in the instrument when it is connected to the
mains power supply. Do not perform any disassembly procedures with power applied to the

Replacement Level Supported

The replacement level supported for this product is to the printed circuit board (PCB) and major
subassembly level. Once you isolate a suspected PCB, follow the procedures in "Repair and
Disassembly" on page 139 to exchange the PCB with a known good replacement. Check to see if the
symptom disappears and that the monitor passes all performance tests. If the symptom persists, swap
back the replacement PCB with the suspected malfunctioning PCB (the original PCB that was installed
when you started troubleshooting), and continue troubleshooting as directed in this chapter.
