SAFETY

15.To prevent electric shock, do not use this polarized plug with an exten- sion cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.

Pour préevenir les chocs électriques ne pas utiliser cette Þche polariseé avec un prolongateur, un prise de courant ou une autre sortie de cou- rant, sauf si les lames peuvent être insérées à fond sans laisser aucune parIIIe à découvert.

16.Grounding or Polarization — Precautions should be taken so that the grounding or polarization means of the Component is not defeated.

This apparatus does not exceed the Class A/Class B (whichever is ap- plicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Ca- nadian Department of Communications.

ATTENTION — Le présent appar- eil numérique n'émet pas de bruits radioélectriques dépassant las limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le règlement sur le brouillage radioélectrique édicté par les ministere des communications du Canada.

WARNING – TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,

DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CAUTION: TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE

OF PLUG TO WIDE SLOT, FULLY INSERT.

ATTENTION: POUR ÉVITER LES CHOCS ÉLECTRIQUES, INTRO-

DUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE

NOTE TO CATV INSTALLER

This reminder is to call the CATV system installer's attention to Article 820-40 of the NEC that provides guide- lines for proper grounding and in particular, specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

OUTSIDE ANTENNA GROUNDING

If an outside antenna is connected to the receiver, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper grounding of the lead-in wire to an antenna-discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. See Figure above.
