Portable and mobile RF communications
equipment should be used no closer to any
part of the Wallach Colposcope, including
cables , than the recommended separation

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 Wallach Colposcopes
are used exceeds the applicable RF compliance level above, the Wallach Colposcope should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Wallach Colposcope.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
