Bluesound DUO D30 Quick start guide: ENGLISH ENGLISH

not be placed in a built-in installation such as a bookcase or rack unless proper 

ventilation is provided or the manufacturer’s instructions have been adhered to.

11.  Power Sources - This product should be operated only from the type of power source 

indicated on the marking label. If you are not sure of the type of power supply to 

your home, consult your product dealer or local power company. 

The primary method of isolating the device from the mains supply is to disconnect 

the mains plug. Ensure that the mains plug remains accessible at all times. Unplug 

the AC power cord from the AC outlet if the unit will not be used for several months 

or more.  The socket-outlet shall be installed near the equipment and shall be easily 

accessible. 

12.  Grounding or Polarization - This product may be equipped with a polarized 

alternating-current line plug (a plug having one blade wider than the other). This plug 

will fit into the power outlet only one way. This is a safety feature. If you are unable 

to insert the plug fully into the outlet, try reversing the plug. If the plug should still 

fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the 

safety purpose of the polarized plug.

13.  Power Cord Protection - Power-supply cords should be routed so that they are not 

likely to be walked on or pinched by items placed upon or against them, paying 

particular attention to cords at plugs, convenience receptacles, and the point where 

they exit from the product. 

14.  Outdoor Antenna Grounding - If an outside antenna or cable system is connected 

to the product, be sure the antenna or cable 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 mast and supporting structure, grounding of the lead-in wire to an 

antenna discharge unit, size of grounding conductors, location of antenna discharge 

unit, connection to grounding electrodes, and requirements for the grounding 

electrode.

15.  Lightning - For added protection for this product during a lightning storm, or when 

it is left unattended and unused for long periods of time, unplug it from the wall 

outlet and disconnect the antenna or cable system. This will prevent damage to the 

product due to lightning and power line surges.

16.  Power Lines - An outside antenna system should not be located in the vicinity of 

overhead power lines or other electric light or power circuits, or where it can fall into 

such power lines or circuits. When installing an outside antenna system, extreme 

care should be taken to keep from touching such power lines or circuits as contact 

with them might be fatal.

17.  Overloading - Do not overload wall outlets, extension cords, or integral convenience 

receptacles as this can result in a risk of fire or electric shock. 

18.  Object and Liquid Entry - Never push objects of any kind into this product through 

openings as they may touch dangerous voltage points or short out parts that could 

result in a fire or electric shock. Never spill liquid of any kind on the product. 

 WARNING

: 

THE APPARATUS SHOULD NOT BE EXPOSED TO DRIPPING OR SPLASHING, 

AND OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, SHOULD NOT BE 

PLACED ON THE APPARATUS. AS WITH ANY ELECTRONIC PRODUCTS, USE 

CARE NOT TO SPILL LIQUIDS INTO ANY PART OF THE SYSTEM. LIQUIDS CAN 

CAUSE A FAILURE AND/OR A FIRE HAZARD.

19.  Damage Requiring Service - Unplug this product from the wall outlet and refer 

servicing to qualified service personnel under the following conditions: 

•  When the power supply cord or plug is damaged. 

•  If liquid has been spilled, or objects have fallen into the product.

•  If the product has been exposed to rain or water. 

•  If the product does not operate normally by following the operating instructions. 

Adjust only those controls that are covered by the operating instructions as an 

improper adjustment of other controls may result in damage and will often require 

extensive work by a qualified technician to restore the product to its normal 

operation.

•  If the product has been dropped or damaged in any way. 

•  When the product exhibits a distinct change in performance – this indicates a 

need for service.

20. Replacement Parts - When replacement parts are required, be sure the service 

technician has used replacement parts specified by the manufacturer or have the 

same characteristics as the original part. Unauthorized substitutions may result in 

fire, electric shock, or other hazards. 

21.  Safety Check - Upon completion of any service or repairs to this product, ask the 

service technician to perform safety checks to determine that the product is in proper 

operating condition. 

22.  Heat - The product should be situated away from heat sources such as radiators, 

heat registers, stoves or other products (including amplifiers) that produce heat.

WARNING

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS 

PRODUCT TO RAIN OR MOISTURE.
