13.  Unplug this apparatus during lightning storms or when unused for 

long periods of time. 

14.  Refer all servicing to qualified service personnel. Servicing is required 

when the apparatus has been damaged in any way, such as the power-

supply cord or plug having been damaged, liquid has been spilled or 

objects have fallen into the apparatus, the apparatus has been exposed 

to rain or moisture, does not operate normally, or has been dropped.

WARNING: 

  -  Do not place the unit in an enclosed space; if you wish to place the 

unit on a shelf, use the top shelf to allow maximum ventilation. Do not 

put any objects on top of this unit. Do not situate it on a rug or other 

soft surface and do not obstruct any air inlets or outlet grilles. Do not 

cover the ventilation grilles with items such as newspapers, tablecloths, 

curtains, etc.

  -  To reduce the risk of fire or electric shock, do not expose this apparatus 

to rain or moisture . This unit must not be used near water or exposed 

to dripping or splashing water or other liquids. No objects filled with 

liquid, such as vases, shall be placed on the unit.

  -  Danger of explosion if battery is incorrectly replaced. Replace only with 

the same or equivalent type.

  -  The battery (battery pack or batteries installed) shall not be exposed to 

excessive heat such as sunshine, fire or the like. 

  -  The unit must be installed in a manner that makes disconnection of 

the mains plug from the mains socket outlet (or appliance connector 

from the rear of the unit) possible. Where the mains plug is used as the 

disconnect device, the disconnect device shall remain readily operable.

  -  Please refer to the information on the exterior rear panel for electrical 

and safety information before installing or operating the apparatus.

  -  Only use the mains cord supplied with this unit.

Use of the apparatus in tropical climates - The equipment shall be used at 

a maximum 45 degree C ambient temperature. 

The unit is of Class 1 construction and must be connected to a mains socket 

outlet with a protective earthing connection.

The lightning flash with the arrowhead symbol within an equilateral 

triangle is intended to alert the user to the presence of un-insulated 

'dangerous voltage' within the product’s enclosure that may be of sufficient 

magnitude to constitute a risk of electric shock to persons.

Warning

: To reduce the risk of electric shock, do not remove cover (or 

back) as there are no user-serviceable parts inside. Refer servicing to 

qualified personnel.

The exclamation point within an equilateral triangle is intended to 

alert the user to the presence of important operating and maintenance 

instructions in the service literature relevant to this appliance.

VENTILATION

Important! The unit will become hot when in use. Do not stack multiple 

units on top of each other. 

Ensure that small objects do not fall through any ventilation grille. If this 

happens, switch off immediately, disconnect from the mains supply and 

contact your dealer for advice.

POSITIONING

Choose the installation location carefully. Avoid placing it in direct 

sunlight or close to a source of heat. No naked flame sources, such as 

lighted candles, should be placed on the unit. Also avoid locations subject 

to vibration and excessive dust, cold or moisture. The unit can be used in 

a moderate climate. 

This unit must be installed on a sturdy, level surface. Do not place in a 

sealed area such as a bookcase or in a cabinet. Do not place the unit on 

an unstable surface or shelf. The unit may fall, causing serious injury to a 

child or adult as well as serious damage to the product. Do not place other 

equipment on top of the unit.

Due to stray magnetic fields, turntables or CRT TVs should not be located 

nearby due to possible interference.

Electronic audio components have a running in period of around a week (if 

used several hours per day). This will allow the new components to settle 

down and the sonic properties will improve over this time.

POWER SOURCES 

The unit 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.

If you do not intend to use this unit for a long period of time, unplug it from 

the mains socket.

OVERLOADING 

Do not overload wall outlets or extension cords as this can result in a risk 

of fire or electric shock. Overloaded AC outlets, extension cords, frayed 

power cords, damaged or cracked wire insulation and broken plugs are 

dangerous. They may result in a shock or fire hazard. 

Be sure to insert each power cord securely. To prevent hum and noise, do 

not bundle the interconnect leads with the power cord or speaker leads.

CLEANING

To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any 

cleaning fluids containing alcohol, ammonia or abrasives. Do not spray an 

aerosol at or near the unit.

BATTERY DISPOSAL

Batteries may contain substances harmful to the environment. Please 

dispose of any discharged batteries with due consideration and in 

accordance with local environmental/electronic recycling guidelines.

SERVICING

or reconstruct the unit if there seems to be a problem. A serious electric 

shock could result if this precautionary measure is ignored. In the event of 

a problem or failure, please contact your dealer.
