RISK OF ELECTRIC SHOCK

DO NOT OPEN 

CAutION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK.

DO NOT REMOVE COVER (OR BACK).

NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

WARNING

To prevent fire or shock hazard, do not
expose the unit to rain or moisture.

*WARNING FOR YOUR PROTECTION PLEASE READ THE FOLLOWING-WATER AND MOISTURE: Unit should not be used near water(e.g.

not fall and liquids are not spilled into the enclosure through openings.

*CLASS 2 WIRING (Adjacent to speaker terminal): The speaker output of this apparatus can exceed 10 Watts and could be a shock injury.

Connection to speakers should be performed by a skilled person.

*Do not install this equipment in a confined space such as a book case or similar unit.
*This apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such vases, shall be placed on the apparatus.
*This apparatus shall be connected to a mains socket outlet with a protective earthing connection.
*It has heed to be easy to disconnect the device. To disconnect the device from power, separate AC input cable from inlet or unplug the AC Cord.

CAutION

*These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any servicing

other than that contained in the operating instructions unless you are qualified to do so.

This equipment has been tested and found to comply with the limits for a Class A digital device,  pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against  harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense. 

This  symbol  is  intended  to  alert  the  user  to  the
presence  of  uninsulated  “dangerous  voltage”  within
the  product’s  enclosure  that  may  be  of  sufficient
magnitude  to  constitute  a  risk  of  electric  shock  to
persons.

This  symbol  is  intended  to  alert  the  user  to  the
presence  of  important  operation  and  maintenance
(servicing)  instructions  in  the  literature  accompanying
the appliance.

Caution: To prevent electric shock do not use this (polarized) plug with

an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.

Attentions: Pour  prévenir  les  chocs  électriques  ne  pas  utiliser  cette

fiche  polarisée  avec  un  prolongateur,  une  prise  de  courant
on  une  autre  sortie  de  courant,  sauf  si  les  lames  peuvent
étre  insérées  à  fond  sans  en  laisser  aucune  partie  à
découvert.
