MANUFACTURER’S DECLARATION-ELECTROMAGNETIC IMMUNITY
This equipment should be used in the electromagnetic environment specified below. User should assure that it is used in such
an environment.

Conducted RF
IEC 61000-4-6
3 Vrms
150k~80MHz
3 Vrms Portable and mobile RF communications
equipment should be used no closer to any parts
than the recommended separation distance that
calculated from the equation applicable to the
frequency of the transmitter. Recommended
separation distance:
d = 1.2√p
d = 1.2√p 80MHz to 800 MHz
d = 2.3√p 800MHz to 2.5GHz
Where “p” is the maximum output power rating
of the transmitter in watts according to
transmitter manufacturer and “d” is the
recommended separation distance in meters.
Field strengths from fixed RF transmitters, as
determined by an electromagnetic 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:
Radiated RF
IEC 61000-4-3
3 V/m
80M~2.5GHz
3 V/m
Note1: at 80MHz~800MHz, the higher frequency range applies.
Note 2: these guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and refection
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 this is used exceeds the applicable RF compliance level above, this
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating.
b) Field strengths should be less than 3V/m in the frequency range of 150k~80MHz.
