Radio Frequency Energy 

 

 

Shielded cables must be used with this equipment to maintain compliance with radio 

frequency energy emission regulations and ensure a suitably high level of immunity 

to electromagnetic disturbances. 

 

European EMC directive 89/336/EEC 
This equipment has been tested and found to 
comply with the limits for a class B computing 
device in accordance with the specifications in 
the European standard EN55022. These limits 
are designed to provide reasonable protection 
against harmful interference. This equipment 
generates, uses and can radiate radio frequency 
energy and if not installed and used in 
accordance with the instructions may cause 
harmful interference to radio or television 
reception. However, there is no guarantee that 
harmful interference will not occur in a particular 
installation. If this equipment does cause 
interference to radio or television reception, 
which can be determined by turning the 
equipment on and off, the user is encouraged to 
correct the interference with one or more of the 
following measures: (a) Reorient or relocate the 
receiving antenna. (b) Increase the separation 
between the equipment and the receiver. (c) 
Connect the equipment to an outlet on a circuit 
different from that to which the receiver is 
connected. (d) Consult the supplier or an 
experienced radio / TV technician for help.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

FCC Compliance Statement (United States) 
This equipment generates, uses and can radiate 
radio frequency energy and if not installed and 
used properly, that is, in strict accordance with 
the manufacturer’s instructions, may cause 
interference to radio communication. It has been 
tested and found to comply with the limits for a 
class A computing device in accordance with 
the specifications in Subpart J of part 15 of FCC 
rules, which are designed to provide reasonable 
protection against such interference when the 
equipment is operated in a commercial 
environment. Operation of this equipment in a 
residential area may cause interference, in 
which case the user at his own expense will be 
required to take whatever measures may be 
necessary to correct the interference. Changes 
or modifications not expressly approved by the 
manufacturer could void the user’s authority to 
operate the equipment. 
 
Canadian Department of Communications 
RFI statement 
This equipment does not exceed the class A 
limits for radio noise emissions from digital 
apparatus set out in the radio interference 
regulations of the Canadian Department of 
Communications. 
 
Le présent appareil numérique n’émet pas de 
bruits radioélectriques dépassant les limites
