TCP - Display Calibration

The following paragraphs describe the calibration procedure for the Display Assembly PCB. Figure 3—10 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 Jl ribbon cable underneath C32 on the Power Conversion PCB to prevent strain on the capacitor during the following tests.
