Portable and mobile RF communications
equipment should be used no closer to the
NQuire than the recommended 10cm
separation distance. The NQuire has been
designed to meet EMC standards.
However, should you suspect that the
device performance (eg. Wi-Fi signal) is
affected by other equipment, move the
device away from the possible cause of
interference.
