  CAUTION!

 

 Conducted and radiated noises in this unit are limited as per the applicable 
National / International Standards as detailed under Compliance: EMC in 
Section 8.

 

 This unit 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 communications. However, this does not guarantee that 
interference will not occur in a particular installation. If this equipment does 
cause harmful interference to radio or television reception, which can be 
determined by turning the equipment off and on, the user is encouraged to 
try to correct the interference by one or more of the measures recommended 
in the following paragraphs.

!

  ATTENTION!

 

 Bruits et rayonnement dans cette unité sont limitées que par la législation 
nationale / normes internationales comme détaillé dans le cadre de 
conformité : EMC dans la section 8.

 

 Cet appareil génère, utilise et peut émettre une énergie de fréquence 
radio et, s’il n’est pas installé et utilisé conformément aux instructions, peut 
causer des interférences nuisibles aux communications radio. Cependant, 
cela ne garantit pas qu’aucune interférence ne se produira dans une 
installation particulière. Si cet équipement provoque des interférences 
nuisibles à la réception radio ou télévision, ce qui peut être déterminé en 
éteignant l’équipement, l’utilisateur est encouragé à essayer de corriger les 
interférences en prenant une ou plusieurs des mesures recommandées dans 
les paragraphes suivants.

6.2  UN-INTENTIONAL RF NOISE GENERATED BY SWITCHED MODE 
POWER SUPPLIES (SMPS)

Switched Mode Power Supplies (SMPS) employ high frequency switching (20 to 30.5 
KHz in these units) and thus, are a source of radio interference, a recipient of radio 
interference and a conduit of radio interference. (Older Linear Type, low frequency 
50 / 60 Hz transformer based power supplies do not employ high frequency switching 
voltages and will be quieter as compared to SMPS).

The emission sources originate in the switching devices due to their fast switching 
current transitions: harmonics of the switching frequency and broadband noise created 
by under-damped oscillations in the switching circuit. The noise is both conducted and 
radiated through the input power cord and the DC output wiring to the radio.
