English 27 GUIDANCE AND MANUFACTURER'S DECLARATION - ELECTROMAGNETIC IMMUNITY:The goLITE BLU is intended for use in the electromagnetic environment specified below.The customer or the user of the goLITE BLU should make sure 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 the goLITE BLU, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. 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 3 V 3 V/m Recommended separation distance: d = 1.2 d = 1.2 d = 2.3 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: 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 goLITE BLU is used exceeds the applicable RF compliance level above, the goLITE BLU should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the goLITE BLU. b: Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
