EMC 

The  equipment  has  been  tested  and  found  to  meet  the  CE-
regulations  relating  to  EMC,  and  complies  with  the  limits  for  a 
Class B device, pursuant to Part 15 of the FCC rules. 

These limits 

are  designed  to  provide  reasonable  protection  against  interference  to 
radio  communications  in  any  installation.  The  equipment  generates, 
uses and can radiate radio frequency energy; improper use or special 
circumstances  may  cause  interference  to  other  equipment  or  a 
performance decrease due to interference radiated by other equipment. 
In  such  cases,  the  user  will  have  to  take  appropriate  measures  to 
reduce such interactions between this and other equipment. 

Any interruption of the shielding inside or outside the equipment could 
cause the equipment to be more prone to fail EMC requirements. 

Non-video  signal  lines  must  use  appropriate  shielded  CAT5  cabling 
(S-FTP), or at least an equivalent. 
If  system  components,  such  as  cabling  (e.g.  coaxial  cable, 
data/audio/cc wiring) and/or the units, are used outdoors, ensure that 

all 

electrically  connected  components  are  carefully  earthed  and 

protected against surges (high voltage transients caused by switching 
or lightning). 

 

ESD 

Electrostatic  discharge  (ESD)  can  damage  or  destroy  electronic 
components.  Proper  precautions  should  be  taken  against  ESD 
when opening the equipment.

9. Product disposal 

 

Recycling 

The unit contains valuable materials which qualify for 
recycling.  In  the  interest  of  protecting  the  natural 
environment, properly recycling the unit  at the end of 
its service life is imperative.
