If use of such devices cannot be avoided, be sure to connect an isolation transformer to the power supply of the connected device or connect an isolator between the connection cables to isolate the power supply, and verify that the risk of electric shock from the system has been sufficiently reduced to levels that conform to IEC 60601-1 standards.
Editing recorded data
Record images to external media, and use commercially available software to play back or edit the images on a computer as necessary.
Network file transfer
Transfer recorded data from the operating room directly to computers within the hospital network.

WARNING
Using this unit for medical purposes
The connectors on this unit are not isolated.
Do not connect any device other than one which conforms to IEC 60601-1 standards.
When an information technology device or AV device that uses an alternating current is connected, current leakage may result in an electric shock to the patient or operator.
If use of such a device is unavoidable, isolate its power supply by connecting an isolation transformer, or by connecting an isolator between the connecting cables.
After implementing these measures, confirm that the reduced risk now conforms to IEC 60601-1 standards.
