Compliance to the Electromagnetic Immunity (2)
The DS-8200 System is intended for use in the electromagnetic environment specified below. The
customer or the user of the DS-8200 System should assure that it is used in such an environment.
Guidance and Manufacturer's Declaration - Electromagnetic Immunity

Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the DS-8200 System, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended Separation Distance
Conducted RF
IEC 61000-4-6
3Vrms
150kHz to 80MHz 3Vrms
d = 1.2
P
Radiated RF
IEC 61000-4-3
3V/m
80MHz to 2.5GHz 3V/m
d = 1.2 P 80MHz to 800MHz
d = 2.3
P
800MHz to 2.5GHz
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 meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
*1
,
should be less than the compliance level in each
frequency range
*2
.
Interference may occur in the vicinity of
equipment marked with the following symbol:
Note 1 : At 80MHz and 800MHz, 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.
*1: 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 can not 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 DS-8200 System is used exceeds the applicable RF compliance
level above, the DS-8200 System should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the DS-8200 System.
*2: Over the frequency range 150kHz to 80MHz, field strength should be less than 3V/m.
