Ventilation

IMPORTANT

  –  The  unit  will  become  hot  when  in  use.  Do  not  stack 

multiple units on top of each other. Do not place in an enclosed area 

such as a bookcase or in a cabinet without sufficient ventilation. 
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.
This unit can be left in Standby mode when not in use and will draw 

<0.5W in this state. To turn the unit off, switch off at the rear panel. 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.

Loudspeakers

Before making any connections to loudspeakers, make sure all power is 

turned off and only use suitable interconnects.

Servicing 

These  units  are  not  user  serviceable.  Never  attempt  to  repair, 

disassemble 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.

Plug Fitting Instructions (UK only)

The cord supplied with this appliance is factory-fitted with a UK mains 

plug  fitted  with  a  5-amp  fuse  inside.  If  it  is  necessary  to  change 

the fuse, it is important that a 5-amp fuse is used. If the plug needs 

to be changed because it is not suitable for your socket, or becomes 

damaged, it should be cut off and an appropriate plug fitted following 

the wiring instructions below. The plug must then be disposed of safely, 

as insertion into a mains socket is likely to cause an electrical hazard. 

Should it be necessary to fit a 3-pin BS mains plug to the power cord, the 

wires should be fitted as shown in this diagram. The colours of the wires 

in the mains lead of this appliance may not correspond with the coloured 

markings identifying the terminals in your plug. Connect them as follows:
The wire which is coloured BLUE must be 

connected to the terminal which is marked 

with the letter ‘N’ or coloured BLACK.
The wire which is coloured BROWN must 

be connected to the terminal which is 

marked with the letter ‘L’ or coloured RED.
The  wire  which  is  coloured  GREEN/

YELLOW  must  be  connected  to  the 

terminal which is marked with the letter ‘E’ 

or coloured GREEN.
If a standard 13-amp (BS 1363) plug is used, a 5-amp fuse must be 

fitted or, if any other type of plug is used, a 5-amp fuse must be fitted, 

either in the plug or adaptor, or on the distribution board.
