C A U T I O N For example, connect a cable with alligator clips between the rear deck chassis and the front deck chassis, or connect a BNC cable from one of the BNCs on the system board to a known grounded BNC on your workbench.
  • Page 86 Troubleshooting USE AN EXTERNAL FAN TO AVOID OVERHEATING COMPONENTS ! C A U T I O N When you remove the oscilloscope cover and main shield, use an external fan to provide continuous air flow over the heat sinks. Air flow over the heat sinks is reduced when the cover and main shield are removed, which leads to higher than normal operating temperatures.
