Further Tips And Advice; Running-In - NAIM 200 Serie Mode D'emploi

5.3 Mains Circuits and Interference
A hi-fi system usually shares a mains power circuit with other household
equipment, some of which can cause distortion that may manifest as
mechanical hum from mains transformers, including the large transformer in
your NAP 250.
Transformer hum is not transmitted through the speakers and has no effect
on the performance of the system; however, careful positioning of your Naim
system may reduce it, as may a separate, dedicated mains circuit. Such a
circuit (ideally with a 30 or 45 Amp rating) will also generally improve system
performance. Only seek advice on the installation of a separate mains circuit
from a qualified electrician.
5.4 Lightning Precautions
Your Naim system should be turned off and fully disconnected from mains
power when there is a risk of a lightning strike, to protect from potential
damage.

6. Further Tips and Advice

Now you have all the essentials sorted, let us move onto a few more things
that you can do to optimise the performance of your new NAP 250.
6.1 Running In
Naim products are hand-crafted from a carefully selected range of high-
quality components. Your NAP 250 will sound superb out of the box, but
its performance may improve further still as all these various components
power up and interact in their first few weeks of use. Keeping your system
powered up will assist this process.
6.2 Cleaning Your Product and Connections
Naim recommends using only the supplied cleaning cloth to lightly dust
any product surfaces. Cleaning products may contain ingredients that can
adversely affect cosmetic surface treatments and coatings.
Keep interconnect plugs and sockets clean and free from corrosion. The
easiest way to achieve this is to fully power off your Naim product (and any
connected equipment), unplug all connections from their sockets and firmly
push them in again. Contact cleaners and so-called 'enhancers' should not be
used, as they can leave deposits that can degrade the sound of your system.
6.3 Resetting your NAP 250
To reset your NAP 250 to default settings, press the 'Brightness' button on the
rear panel for 3 seconds.
