12.4 Guidelines and Manufacturer's Statement - Electromagnetic In-
terference Immunity
Note 1: The higher frequency range applies for 80 and 800 MHz.
Note 2: These guidelines are probably not realizable in all cases. The distribution
and spread of electromagnetic quantities differs depending on the absorption
and reflection of buildings, objects, and people.

The field strength of stationary transmitters such as base stations of wireless
phones and cell phones, ham radio operators, AM and FM radio and TV stations
can theoretically not always determined in advance. A study of the installation
site should be considered to determine the electromagnetic environment con-
cerning the stationary transmitter. If the measured field strength at the pro-
posed Aquilex Fluid Control System installation and operation site exceeds the
concordance levels listed above, the Aquilex Fluid Control System should be mon-
itored to document proper functionality and operation as intended. If unusual
performance characteristics are observed, additional measures may be required
such as changing orientation or the location of the Aquilex Fluid Control System.
