Olympus DP73 Instruction Manual page 8

The area (IC) of the PCIe interface board becomes very hot during and immediately after use of the
camera. Be careful never to touch them during and after use.
5. For handling of the computer, refer to the separately provided "Computer User's Manual".
6. Connect the power cord correctly and ensure that the grounding
terminal of the power supply and wall outlet are properly connected.
If the equipment is not grounded/earthed, Olympus can no longer
warrant the electrical safety performance of the equipment.
7. Lay out the interface cable so that it does not contact the heat
generating section such as the lamp housing of the microscope.
8. After operation or in case of abnormality, be sure to disconnect the
power cord from the connector on the microscope or from the wall
power outlet.
9. Never insert foreign objects into the air vents as this could result in
fire and electrical shock.
