NOTICE FOR CUS TOMERS IF YOUR UNIT IS EQUIPP ED WIT H A
POWE R CORD.
WARNING: THIS APPLIANCE SHALL BE CONNECTED TO A MAINS
SOCKET OUTLET WITH A PROTECTIVE EARTHING CONNECTION.
The cores in the mains lead are coloured in accordance with the following code:
GREEN and YELLOW - Earth BLUE - Neutral BROWN - Live
As colours of the cores in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug,
proceed as follows:
•
The core which is coloured green and yellow must be connected to the
terminal in the plug marked with the letter E, or with the earth symbol, or
coloured green, or green and yellow.
•
The core which is coloured blue must be connected to the terminal
marked N or coloured black.
•
The core which is coloured brown must be connected to the terminal
marked L or coloured red.
This equipment may require the use of a different line cord, attachment
plug, or both, depending on the available power source at installation. If
the attachment plug needs to be changed, refer servicing to qualified service personnel who should refer to the table below. The green/yellow wire
shall be connected directly to the units chassis.

IMPORTANT SAFETY INFORMATION
U.K. MAINS PLUG WARNING
A molded mains plug that has been cut off from the cord is
unsafe. Discard the mains plug at a suitable disposal facility.
NEVER UNDER ANY CIRCUMSTANCES SHOULD YOU INSERT
A DAMAGED OR CUT MAINS PLUG INTO A 13 AMP POWER
SOCKET. Do not use the mains plug without the fuse cover in
place. Replacement fuse covers can be obtained from your local
retailer. Replacement fuses are 13 amps and MUST be ASTA
approved to BS1362.
ELECTROMAGNETIC
COMPATIBILITY
This device complies with part 15 of the FCC Rules and the
Product specifications noted on the Declaration of Conformity.
Operation is subject to the following two conditions:
•
this device may not cause harmful
interference, and
•
this device must accept any interference received, including
interference that may cause undesired operation.
Operation of this unit within significant
electromagnetic fields should be avoided.
•
use only shielded interconnecting cables.
If you want to dispose this product, do not mix it with general household waste. There is a separate collection system
for used electronic products in accordance with legislation
that requires proper treatment, recovery and recycling.
Private household in the 25 member states of the EU, in Switzerland
and Norway may return their used electronic products free of charge to
designated collection facilities or to a retailer (if you purchase a similar
new one).
For Countries not mentioned above, please contact your local authorities
for a correct method of disposal.
By doing so you will ensure that your disposed product undergoes the
necessary treatment, recovery and recycling and thus prevent potential
negative effects on the environment and human health.
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as preamplifiers
or tape decks directly above or below the unit. Because this amplifier has a
high power density, it has a strong magnetic field which can induce hum into
unshielded devices that are located nearby. The field is strongest just above
and below the unit.
If an equipment rack is used, we recommend locating the amplifier(s) in
the bottom of the rack and the preamplifier or other sensitive equipment
at the top.
