•
Use of this equipment adjacent to or stacked with other equipment should be
avoided because it could result in improper operation. If such use is
necessary, this equipment and the other equipment should be observed to
verify that they are operating normally.
•
Using accessories other than those specified may result in increased
electromagnetic emissions or decreased electromagnetic immunity of the
Narcotrend-Compact M.
•
Portable and mobile radio frequency communication devices (incl. antennas)
can affect the equipment. There should be a distance of at least 30 cm (12
inches) to the Narcotrend-Compact M and its accessories.
•
The equipment is not designed for use in MRI environment.
•
In case of simultaneous use of the device together with other systems or
devices, the sum of all leakage currents is not allowed to exceed the
permissible values:
(in accordance with IEC 60601-1: 100 µA (AC) and 10µA (DC)).
•
When using a high-frequency surgical device, care must be taken to ensure
that the EEG electrodes are correctly placed (refer to the section "Applying
the electrodes"). In order to reduce the risk of burns and irritation to the skin
during use, EEG electrodes may not be situated between the operation area
and the neutral electrode. It is also absolutely necessary to follow the use and
safety instructions included with the high-frequency surgical device. It is
forbidden to continue to operate the system if the neutral electrode is
defective.
•
During the use of diathermy/high-frequency surgical devices, disturbances
may occur in the EEG signal or in automatic classification.
•
Whenever the failure of the device or the limitation of the proper function of
the device becomes detectable, this is always a clear indication of a defect. In
such cases, further operation of the device is then no longer permissible. The
device must then be subjected to proper inspection by an expert.
•
No assembly tasks must be carried out on the components of the device,
since trouble-free operation can no longer be guaranteed in such cases. It is
not allowed to open the device and to make any changes to the cables or
electrodes.
•
The electrodes and the push button adapters may only be placed on the
patient’s head, because otherwise other patient’s applications could be
disturbed.
•
The electrodes and the push buttons adapters must not come into contact
with electrically conductive parts and earth.
•
At any time, it must be possible to separate the device from the mains supply
by disconnecting the mains plug. Consider this when placing the device.
•
As a general rule, always avoid that anything external comes into contact with
the electrical connector pins.
•
The patient should not be touched at the same time as the interfaces and the
DC connectors of the Narcotrend-Compact M - power supply.
