17 EMC INFORMATION Guidance and manufactures declaration electromagnetic emission TC300 is intended for use in the electromagnetic environment specified below. The customer or the user of TC300 should assure that they are used in such an environment. Emission test Compliance Electromagnetic environment guidance RF emissions CISPR 11 RF emission CISPR 11 Harmonic emissions IEC/EN 61000-3-2 Voltage fluctuations/

flicker emissions IEC/EN 61000-3-3 Group 1 Class B N/A N/A TC300 uses RF energy only for their internal function. Therefore, their RF emissions are very low and are not likely to cause any interference in nearby electronic device. TC300 is suitable for use in all establishments, other than domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes. NOTE The EMISSIONS characteristics of TC300 make it suitable for use in industrial areas and hospitals (CISPR 11 class A). If it is used in a residential environment (for which CISPR 11 class B is normally required) TC300 might not offer adequate protection to radio-frequency communication services. The user might need to take mitigation measures, such as relocating or re-orienting the device.

NOTE 1 NOTE 2 At 80 MHz and 800 MHz, the higher frequency range applies. 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 TC300 is used exceeds the applicable RF compliance level above, TC300 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating TC300. b. Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3V/m. c.
