The device is intended for use in an electromagnetic environment in which radiated therefore disturbances are controlled. The customer or the user of the
device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the device as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using
the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higer frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.

Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the device, including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended seperation distance:
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 metres (m).
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.
