Figure 3-10 Output Waveform
TCP-Display The following paragraphs describe the calibration procedure for the Display
Calibration Assembly PCB. Figure 3-11 shows the location of all Display Assembly
PCB potentiometers.
1. Disconnect the ac power cord. Remove front and rear cases to allow
access to the potentiometers. For disassembly instructions, refer to
page 4-8, Case Separation.
Warning SHOCK HAZARD. The Display Assembly produces high voltages up to
+11.6kV. Do not contact the CRT anode connector or the CRT bias
generator circuitry when the defibrillator/monitor power is on.
Warning FLYING GLASS HAZARD. The CRT is made of glass and contains a
vacuum which may implode if broken. Handle with care and wear safety
glasses when removing the CRT from the Display Assembly PCB.
2. Reconnect the ac input cord. Reconnect J1 on the front panel.
Note: Reroute Ji ribbon cable underneath C32 on the Power Conversion
PCB to prevent strain on the capacitor during the following tests.
