CIRRUS HD-OCT User Manual 2660021169012 Rev. A 2017-12Electromagnetic Compatibility (EMC) 1- 11Guidance and manufacturer’s declaration – electromagnetic emissionsThe CIRRUS HD-OCT is intended for use in the electromagnetic environment specified below. The customer or user of the CIRRUS HD-OCTshould assure that it is used in such an environment.Emissions Test Compliance Electromagnetic environment – guidanceRF emissionsCISPR 11Group 1The CIRRUS HD-OCT uses RF energy only forits internal function. Therefore, its RFemissions are very low and are not likely tocause any interference in nearby electronicequipment.RF emissionsCISPR 11Class A The CIRRUS HD-OCT CIRRUS are suitable foruse in all establishments other than domesticestablishments and those connected to a lowvoltage power supply network which suppliesbuildings used for domestic purposes.Harmonic emissionsIEC 61000–3–2Class AVoltage fluctuations/flicker emissionsIEC 61000–3–3CompliesGuidance and manufacturer’s declaration – electromagnetic immunityThe CIRRUS HD-OCT is intended for use in the electromagnetic environment specified below.
