• Recommended separation distances between portable and mobile RF communication equipment and
the device.
The device is intended for use in an electromagnetic environment where radiated RF disturbances are under
control. User can help prevent electromagnetic interference by keeping the device at a minimum distance from
portable and mobile RF communications equipment (transmitters). Below table details the maximum output
power of transmitter:
Electromagnetic environment – guidance
RF energy is used only to maintain device's operation. Therefore,
its RF emissions are so low that it's not likely to cause any
interference in nearby electronic equipment.
The device 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.

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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher 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.

Field strengths from fixed RF transmitters, as determined by an elec-
tromagnetic 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 and 800 MHz, the higher 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 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 as reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
