Guidance
This device is intended for use in the electromagnetic en
vironment specified below.
The customer and/or user of this device should ensure that it is used in such an environment.
Portable and mobile RF communications equipment should be used no closer to any part of the device,
includ
ing cables, than the recommended separation distance calculated from 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 and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
de
termined by an electromagnetic site survey

,
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of
equipment marked with the symbol:
NOTES:
1. At 80 MHz and 800 MHz, the higher frequency range applies.
2. These guidelines may not apply in all situation
s. 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 device is
used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is
observed, 
additional measures may be necessary, such a
s reorienting or relocating the device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
