ELECTROMAGNETIC COMPATIBILITY (EMC) • Guidance and manufacturer's declaration - electromagnetic emissions The device is intended for use in the electromagnetic environments listed below, and should only be used in such environments: Emissions test Compliance Electromagnetic environment - guidance RF emissions CISPR 11 RF emissions CISPR 11 Group 1 Class B RF energy is used only to maintain device's operation. Therefore, its RF emissions are so low that it's not likely to cause any interference in nearby electronic equipment. Harmonic emissions IEC 61000-3-2 Voltage fluctuations/ flicker emissions IEC 61000-3-3 Not Applicable Not Applicable The device is suitable for use in all establishments, including domestic establishments, and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes. • Guidance and manufacturer's declaration - electromagnetic immunity The device is intended for use in the electromagnetic environments listed below, and should only be used in such environments: Immunity test IEC 60601 test level Electrostatic ± 6 kV contact discharge (ESD) ± 8 kV air IEC 61000-4-2 Compliance level ± 6 kV contact ± 8 kV air Electromagnetic environment- guidance Floors should be wood, concrete or ceramic tile. If floors are covered with synthetic material, the relative humidity should be at least 30 %. Power frequency (50/60 Hz) magnetic field IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic fields should be at levels characteristic of a typical location in a typical commercial or hospital environment. • Recommended separation distances between portable and mobile RF communication equipment and the device. The device is intended for use in an electromagnetic environment where radiated RF disturbances are under control. User can help prevent electromagnetic interference by keeping the device at a minimum distance from portable and mobile RF communications equipment (transmitters). Below table details the maximum output power of transmitter: Rated maximum output power of transmitter W Separation distance according to frequency of transmitter m 150 kHz to 80 MHz Not Applicable 80 MHz to 800 MHz d = 1.2 800 MHz to 2.5 GHz d = 2.3 0.01 NA 0.12 0.23 0.1 NA 0.38 0.73 1 NA 1.2 2.3 10 NA 3.8 7.3 100 NA 12 23 26 For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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 affected by absorption and reflection from structures, objects and people. • Guidance and manufacturer's declaration - electromagnetic immunity The device is intended for use in the electromagnetic environments listed below, and should only be used in such environments: Immunity IEC 60601 Compliance Electromagnetic environment - guidance test test level level Conducted RF IEC 610004-6 Radiated RF IEC 610004-3 3 Vrms 150 kHz to 80 MHz 3 V/m 80 MHz to 2.5 GHz Not Applicable 3 V/m Portable and mobile RF communications equipment should be used no closer to any part of the device, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance d = 1.2 80 MHz to 800 MHz d = 2 .3 800 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 metres (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: 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 affected by absorption and reflection 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 the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the device. b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. 27
