19Field strengths from fixed RFtransmitters, as determined byan electromagnetic site survey,a should be less than thecompliance level in eachfrequency range. bInterference may occur in thevicinity of equipment markedwith 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. Electromagneticpropagation is affected by absorption and reflection from structures, objects andpeople.a Field strengths from fixed transmitters, such as base stations for radio(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FMradio broadcast and TV broadcast cannot be predicted theoretically with accuracy.To assess the electromagnetic environment due to fixed RF transmitters, anelectromagnetic site survey should be considered. If the measured field strength inthe location in which the model POCm-W22/24C-ULT3 is used exceeds theapplicable RF compliance level above, the model POCm-W22/24C-ULT3 should beobserved to verify normal operation. If abnormal performance is observed,additional measures may be necessary, such as reorienting or relocating the modelPOCm-W22/24C-ULT3.b Over the frequency range 150 kHz to 80 MHz, field strengths should be less thanV/m.Contact InformationIEI Integration Corp.No. 29, Zongxing Rd., Xizhi Dist.,New Taipei City 221, TaiwanTEL: +886-2-8691-6798Fax: +886-2-6616-0028www.ieiworld.comsales@ieiworld.com.tw
