Appendix 1. Electromagnetic Compatibility
Like other electrical medical equipment the system requires special precautions to ensure
electromagnetic compatibility with other electrical medical devices. To ensure electromagnetic
compatibility (EMC) the system must be installed and operated according to the EMC
information provided in this manual.
The system has been designed and tested to comply with IEC 60601-1-2 requirements for EMC
with other devices.
Guidance and manufacturer's declaration – electromagnetic immunity
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.

Make sure the external monitor is connect-
ed to aView using the composite cable and
that the external monitor is displaying the
correct input. The external monitor shall be
capable of receiving NTSC or PAL. Toggle
between NTSC and PAL in the video out
menu on aView for best result. The external
monitor is only displaying a live image
when aView is displaying a live image.
The image size on the external monitor is
determined by the settings in the external
monitor.
Adjust the colours, brightness and contrast
on the external monitor to achieve the
desired result.
If horizontal lines (noise) appear on the
external monitor, try to connect the aView
power supply.
Electromagnetic Environment Guidance
The system use RF energy only for
its internal function. Therefore, its RF
emissions are very low and are not
likely to cause any interference in
nearby electronic equipment.
The system is suitable for use in all
establishments, including domestic
establishments and those directly
connected to the public low-voltage
power supply network that supplies
buildings used for domestic purposes.
Guidance and manufacturer's declaration – electromagnetic immunity
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.
