Mains power should be that of a typical
commercial or hospital environment. If
you require continued operation during
power mains interruptions, ensure that
batteries are installed and charged.
Ensure that battery life exceeds
longest anticipated power outages
or provide additional uninterruptible
power source.
This equipment is intended for use in the electromagnetic environment specified below.
The customer or the user of this equipment should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of the equipment, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter as
below.
Recommended separation distance:
d=1.2/V1]√P
d=1.2/√P 80 MHz to 800MHz
d=2.3√P 800 MHz to 2.5 GHz
Where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and d is
the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey

The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553
MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
