ELECTROMAGNETIC COMPATIBILITY WARNING
Portable RF communications equipment, including peripherals such as antenna
cables and external antennas, must not be closer than 30 cm (12 inches) to any
part of the bed, including cables.
Avoid stacking or placing equipment adjacent to other equipment to prevent
malfunctioning. If such use is necessary, observe stacked or adjacent equipment
carefully to ensure that it is operating correctly.
The use of accessories, transducers and cables, other than those specified or
supplied by the manufacturer, could result in increased electromagnetic
emissions or reduced electromagnetic immunity, and lead to incorrect operation.
