Mains power should be that of a
typical commercial or hospital
environment. If user requires
continued operation during power
mains interruptions insure that
batteries are installed and charged.
Insure that battery life exceeds
longest anticipated power outages
or provide and additional
uninterruptible power source..

Portable and mobile RF
communications equipment should
be used no closer to any part of the,
including cables, than the
recommended separation distance

applicable to the frequency of the
transmitter as below.

transmitter manufacturer and
d is

Interference may occur in the
vicinity of equipment marked with
the following symbol:
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
equipment is used exceeds the applicable RF compliance level above, the equipment should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the equipment.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
