should be used no closer to
any part of the

Field strengths from fixed
RF transmitters, as
determined by an
electromagnetic site survey,
(a) should be less than the
compliance level in each
frequency range (b).
Interference may occur in
the vicinity of equipment
marked with the following
symbol:
NOTE 1: At 80 MHz, the higher the 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
model extriCARE™ 2400
is used
exceeds the applicable RF compliance level above, the
model extriCARE™ 2400
should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the
model extriCARE™ 2400
.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The
model extriCARE™ 2400
is intended for use in the electromagnetic
environment specified below. The customer or the user of the
model
extriCARE™ 2400
should assure that it is used in such an environment.
