Mains power quality should be that of a
typical commercial or hospital
environment. If the user of the FONA
CDRelite USB Interface Module requires
continued operation during mains
interruptions, it is recommended that the
PC workstation to which the FONA
CDRelite USB Interface Module is
connected be powered from an
uninterruptible power supply or battery.
NOTE: U

Portable and mobile RF communication
equipment should be used no closer to any
part of the FONA CDRelite Interface
Module, including its cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

should be less than the compliance
level in each frequency range.

Interference may occur in the vicinity of
equipment marked with the following
symbol.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
