Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The VisionPro SYNK 26” Wireless LED Display and SYNK Wireless Transmitter are intended for use
in the electromagnetic environment specified below�
The customer or the user of the VisionPro SYNK 26” Wireless LED Display and SYNK Wireless Transmitter should ensure that they
are used in such an environment�
Immunity Test
IEC 60601 Test level
Compliance Level
Electromagnetic
Environment - guidance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
6 Vrms
150 kHz to 80 MHz
3 V/m
80MHz to 2�7 GHz
6 Vrms

Portable and mobile RF communications equipment
should be used no closer to any part of the SYNK
Wireless Transmitter system, including its cables,
than the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter�
Recommended Separation Distance
d = 2√P 80 MHz to 2�7 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 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:
(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 the VisionPro SYNK 26” Wireless 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 SYNK 26” Wireless LED Display�
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m�
