Guidance and Manufacturer's Declaration: Electromagnetic Immunity
iSwitch is intended for use in the electromagnetic environment specified below. The customer or
the user of iSwitch should ensure that it is used in such an environment.

(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 iSwitch system is used
exceeds the applicable RF compliance level above, the iSwitch system should be observed to verify normal opera-
tion. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocat-
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
