Electromagnetic environment - guidance
DSK-1031 uses RF energy only for its internal function. Therefore, its RF emissions are
very low and are not likely to cause any interference in nearby electronic equipment.
DSK-1031 is suitable for use in all establishments, including domestic establishments
and those directly connected to the public low-voltage power supply network that
supplies buildings used for domestic purposes.
Compliance level Electromagnetic environment - guidance
±6 kV contact Floors should be wood, concrete or ceramic tile. If
±8 kV air floors are covered with synthetic material, the
relative humidity should be at least 30 %.
±2 kV for power supply lines Mains power quality should be that of a typical

radios 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 DSK-1031 is used exceeds the
applicable RF compliance level above, DSK-1031 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating DSK-1031.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

Table 206 - Recommended separation distances between portable and mobile RF communications equipment and DSK-1031 -
DSK-1031 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of DSK-1031
can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and DSK-1031 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 higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and

Portable and mobile RF communications equipment should be used no closer to any part of
DSK-1031, including 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 metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
should be less than the compliance level in each frequency range.
