Safety Electromagnetic Compatibility
Compliance to the Electromagnetic Immunity (2)
The DS-8500 System is intended for use in the electromagnetic environment specified below. The customer or the
user of the DS-8500 System should assure that it is used in such an environment.
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
Immunity Test
IEC 60601-1-2
Test Level
Compliance
Level
Electromagnetic Environment - Guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the DS-8500
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
Radiated RF
IEC 61000-4-3
3V/m
80MHz to 2.5GHz
3V/m d = 1.2 80MHz to 800MHz
d = 2.3 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 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.
*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-8500
System is used exceeds the applicable RF compliance level above, the DS-8500 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-8500 System.
*2: Over the frequency range 150kHz to 80MHz, field strength should be less than 3V/m.
