Electromagnetic Compatibility
Electromagnetic Interference (EMI) is any signal or emission, radiated in free space or conducted along power
or signal leads, that endangers the functioning of radio navigation or other safety service or seriously
degrades, obstructs, or repeatedly interrupts a licensed radio communications service. Radio communications
services include but are not limited to AM/FM commercial broadcast, television, cellular services, radar, air-
traffic control, pager, and Personal Communication Services (PCS). These licensed radio services, and
unlicensed radio services, such as WLAN or Bluetooth, along with unintentional radiators such as digital
devices, including computer systems, contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic equipment to function properly
together in the electronic environment. While this computer system has been designed and determined to be
compliant with regulatory agency limits for EMI, there is no guarantee that interference will not occur in a
particular installation.
SonicWallproducts are designed, tested, and classified for their intended electromagnetic environment. These
electromagnetic environment classifications generally refer to the following harmonized definitions:
Class B products are intended for use in residential/domestic environments but may also be used in non-
residential/non-domestic environments.
NOTE:
broadcast radio and television receivers may be expected within a distance of 10 m (33
feet) from where this product is used.
Class A products are intended for use in non-residential/non-domestic environments. Class A products
may also be utilized in residential/domestic environments, but may cause interference and require the
user to take adequate corrective measures.
If this equipment does cause interference with radio communications services, which can be determined by
turning the equipment off and on, you are encouraged to try to correct the interference by one or more of the
following measures:
Reorient the receiving antenna.
•
Relocate the computer with respect to the receiver.
•
•
Move the computer away from the receiver.
The residential/domestic environment is an environment where the use of
