ME EQUIPMENT AND ME SYSTEMS
The vacuum unit is intended for use in the electromagnetic environment specified below. The customer or the user of the vacuum 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 vacuum, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
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 transmitter, as determined by an electromagnetic site
survey

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, 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.
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 or system is used exceeds the applicable RF compliance level above, the equipment or system should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
equipment or system.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
