• 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). The table below details
the maximum output power of transmitter:

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.
• Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environments listed below, and should only be used
in such environments:

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.

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.
