In order to comply with current
European safety regulations it is
essential that the Naim loudspeaker
connectors supplied with amplifiers
and loudspeakers are used.

Do not under any circumstances
allow anyone to modify your Naim
equipment without first checking
with the factory, your dealer, or
your distributor. Unauthorised
modifications will invalidate your
guarantee.

For your own safety do not under
any circumstances open Naim
equipment without first
disconnecting the mains.

The following label is attached to
all mains powered equipment:

3.0 Warnings

Naim equipment is designed to offer the finest sound quality that can be achieved,

avoiding compromise wherever possible. This can lead to circumstances that may be

unfamiliar. The material that follows contains advice specifically related to Naim

equipment as well as more general warnings about the use of domestic audio products.

Please read it carefully.

The transformers in Naim power amplifiers and power supplies may sometimes make a

mechanical noise caused by distortion of the mains waveform. Naim transformers are

large in size and have heavy gauge secondary windings making them relatively sensitive

to such distortion. A separate mains circuit for your hi-fi system may reduce the effect

while also giving an overall improvement in sound quality. It may be necessary however

to take account of mechanical transformer noise when siting your equipment.

In some circumstances, depending on where you live and the earthing arrangements in

your home, you may experience radio frequency interference. Controls on broadcasting in

some territories allow very high levels of radio frequency radiation and both the choice

and exact siting of equipment may be critical. If there is a known problem in your locality

it is advisable to arrange for a home demonstration before purchase to find out if Naim

equipment is likely to be affected. Susceptibility to radio frequency interference is related

to the wide internal bandwidth necessary for high sound quality. Systems incorporating

moving coil phono preamplifiers and active crossovers are more likely to suffer. A radio

frequency filter kit is available for some Naim equipment but sound quality will be

progressively compromised as more elements of the kit are fitted. In situations of extreme

radio interference Naim equipment may be unsuitable.

Your Naim hi-fi system can be damaged by lightning. Power amplifiers are particularly at

risk and should be turned off when there is risk of lightning strike. For complete protection

all mains plugs and any aerial cables should be disconnected when not in use.

Equipment must not be exposed to dripping or splashing and no objects filled with liquid,

such as vases, should be placed on the equipment.
