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

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