Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The VisionPro 26” LED Display is intended for use in the electromagnetic environment speci ed below.
The customer or the user of the display should ensure that it is used in such an environment.
Immunity Test IEC 60601 Test level Compliance Level Electromagnetic Environment - Guidance
Portable and mobile RF communications equipment should
be used no closer to any part of theVisionPro 26” LED Display,
including its 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
3 Vrms
150 kHz to 80 MHz
3 V d = 1.17√P
Radiated RF
IEC 61000-4-3
3 V/m
80MHz to 2.5 GHz
3 V/m d = 1.17√P 80 MHz to 800 MHz
d = 2.33√P 800 MHz to 2.5 GHz
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 xed 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:
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 a ected by absorption and re ection
from structures, objects, and people.
(a) Field strengths from xed 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 xed RF transmitters, an electromagnetic site survey should be considered. If the
measured eld strength in the location in which the VisionPro 26” LED Display is used exceeds the applicable RF compliance
level above, the display and transmitter should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the VisionPro 26” LED Display.
(b) Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment
and the VisionPro 26” LED Display
The VisionPro 26” LED Display is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The user of the VisionPro 26” LED Display can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the VisionPro 26” LED Display as
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance (d) in meters (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 a ected by absorption and re ection
from structures, objects, and people.
