1.11. Equipment Malfunction
If either the hospital or equipment circuit breakers trip, an equipment malfunction may be indicated. Do not
attempt to operate the equipment until a qualified service engineer has checked it.
If any of the equipment controls fail to respond as indicated in this manual, you should:
1. Remove power to the equipment by placing the power switch in the off position and unplugging the
power cord from the AC receptacle.
2. Notify a qualified service engineer.
3. Do not operate the equipment until the service technician advises that it is operating properly.
Establish an operation room emergency procudure to ensure patient and user safety in the
event of a system failure.
1.12. Mains Isolation
The system has 2 means to isolate its circuits electrically from the supply mains on all poles simultaneously.
1. Switch the breaker to OFF position.
2. Unplug the power cable.
1.13. External Devices
To ensure patient safety, only connect external equipment that has been approved by GE HUALUN Medical
Systems Co, Ltd. All equipment such as keyboard, wireless mouse, mobile HDD, etc, attached to the
external interface connections must meet the requirements of IEC 60601-1 when operated within the
patient environment. When used outside of the patient environment, each externally connected device
must comply with the relevant IEC/ISO requirements for that device. In any case, the combination of all
externally connected equipment shall not cause the leakage current of any device used within the patient
environment to exceed the limits stated in IEC 60601-1.
Cover the connector when it is not in use to avoid unintentional touch.
Connect only medical devices that comply with UL/IEC 60601 standards. Contact GE
Healthcare for a list of compliant devices. Connecting a non-compliant device could cause
injury to the operator, the patient or the equipment.
