Mains power quality should be
that of a typical commercial or
hospital environments. If the user
of the P280
Mattress
requires
continued operation during
power mains interruptions, it is
recommended that the P280
Mattress
be powered from an
uninterruptible power supply or a
battery.

The field levels emitted by fixed
RF transmitters, as determined
by an electromagnetic
measurement of the site
a
, must
be below the level of compliance
in each frequency band
b
.
Interference may occur close to
devices identified with the
following symbol:
a. The field levels of fixed transmitters, such as radio telephone bases (cell/wireless) and
terrestrial mobile radios, amateur radios and AM, FM and TV communication radios cannot be
theoretically evaluated precisely. Site measurements are required in order to obtain the
electromagnetic environment due to fixed RF transmitters. If the field level measured in the
working environment of the P280 mattress is greater than the above applicable levels of
compliance, the operation of the P280 mattress must be checked. If any anomalies are
detected, additional measures must be taken, such as redirecting or relocating the reference
equipment.
b. The field level must be less than 3V/m above the frequency band 150 kHz to 80 MHz.
Manufacturer's recommendations and declaration – electromagnetic immunity
The P280 Mattress is intended for use in the electromagnetic environment specified
below. The customer or the user of the P280 Mattress should make sure it is used in such
an environment.
