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 
retailer, or your distributor. Unauthorised modifications will 
invalidate your guarantee.

Equipment must not be exposed to dripping or splashing and no 
objects filled with liquid, such as vases, should be placed on the 
equipment.

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

Warning: an apparatus with CLASS I construction shall be 
connected to a mains socket outlet with a protective earthing 
connection.

Warning: batteries installed shall not be exposed to excessive 
heat such as sunshine, fire or the like.

Where the mains plug or an appliance coupler is used as the 
disconnect device, the disconnect device shall remain readily 
operable. To disconnect the equipment from the mains remove 
the mains plug from the mains outlet.

The following label is attached to all mains powered equipment:

interference to radio or television reception, which can be 
determined by turning off and on, the user is encouraged to 
try to correct the interference by one or more of the following 
measures:
