Guidelines and manufacturer’s declaration – Resistance to emitted electromagnetic interference
The device model is intended for use in the electromagnetic environment specified below. The
customer or the user of the device should assure that it is used in such an environment.

environment – guidelines
Portable and mobile RF equipment should be
used no closer to any part of the device,
including cables, than the recommended safety
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended safety distance:

d = 1.2√P for 80 MHz to 800 MHz
d = 2.3√P for 800 MHz to 2.5 GHz
Where P is the rated power of the transmitter in
watts (W) according to the transmitter manufacturer
and d is the recommended safety distance in
metres (m).
The field intensity of stationary radio transmitters,
based on an on-site inspection

, should be less
than the compliance level

Interference may occur in the vicinity of instruments
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 with respect 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 HF
compliance level indicated above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the device.
b
Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
