The AED is suitable for use in the magnetic environment specified below. The customer or
user of the AED must ensure that the device is used in said environment.
Portable and mobile RF
communication devices must be
used at a distance from any part
of the AED , including its cables.
The minimum recommended
distance is calculated based on
the equation that applies to the
transmitter frequency.

Where P is the maximum
transmitter output power
coefficient in watt (W) according to
the manufacturer of the
transmitter and d is the
recommended separation
distance in metres (m).
The field intensities of the fixed
RF transmitters detected by on-
site electromagnetic surveys, a
must be lower than the conformity
level in each frequency range. b
There may be interference near
devices identified by the following
symbol:
Notes: Maximum admissible frequencies between 80 MHz and 800MHz.
Notes: These indications may not be applicable in every situation. Electromagnetic
propagation is affected by its absorption and reflection by structures, objects and people.
a
It is not theoretically possible to predict fixed transmitter field intensities, such as base
stations for radio-telephones (mobile phones / cordless phones), terrestrial mobile radios,
amateur radios, AM and FM radio transmission and TV transmission. To assess the
electromagnetic environment generated by fixed RF transmitters, you will need to perform an
on-site electromagnetic survey. If the field intensity measured in the location where the AED is
used exceeds the applicable RF conformity level provided above, the AED must be monitored
for correct operation. If you discover anomalous performance, it may be necessary to apply
additional measures, such as re-directing or moving the AED
B
) Outside of the frequency range of 80 MHz and 2.5 GHz, the field intensity must be lower
than 10 V/m
