• VOLTAGE SELECTOR 

(For China, Korea and General models)
The voltage selector switch on the rear panel of this 
unit must be set for your local main voltage BEFORE 
plugging this unit into the AC main supply. Voltages 
are 110/120/220/240 V AC, 50/60 Hz.

For U.K. customers

If the socket outlets in the home are not suitable for the 
plug supplied with this appliance, it should be cut off and 
an appropriate 3 pin plug fitted. For details, refer to the 
instructions described below.

Note:

 The plug severed from the mains lead must be 

destroyed, as a plug with bared flexible cord is hazardous 
if engaged in a live socket outlet.

Standby mode

When this unit is turned off by pressing the 
STANDBY/ON button on the front panel, this unit 
consumes a small amount of power.  This state is called 
the standby mode.   This unit’s power supply is 
completely cut off from the AC line only when the 
POWER switch on the rear panel is set in the OFF 
position or the AC power cord is disconnected.

This unit features a magnetically shielded design, but 
there is still a chance that placing it too close to a TV 
set might impair picture color. Should this happen, 
move this unit away from the TV set.

IMPORTANT:

THE WIRES IN MAINS LEAD ARE COLOURED 
IN ACCORDANCE WITH THE FOLLOWING 
CODE:
Blue: NEUTRAL
Brown: LIVE
As the colours of the wires in the mains lead of this 
apparatus may not correspond with the coloured 
markings identifying the terminals in your plug, 
proceed 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.  Making sure that neither core is 
connected to the earth terminal of the three pin plug.
