Guidance and Manufacturer's Declaration: Electromagnetic Immunity
The WiSe™ 26" HDTV Surgical Display and WiSe™ HDTV Transmitter are intended for use
Display and WiSe™ HDTV Transmitter should ensure that they are used in such an environment.
Immunity Test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
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 WiSe™ 26" HDTV Surgical Display is used exceeds the
applicable RF compliance level above, the display and transmitter should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the WiSe™ 26" HDTV Surgical Display.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
