SAFETY INSTRUCTIONS
Read these instructions, and follow them.
Water and moisture
The DNS2000 rackmount processor must not be exposed to rain or moisture. Furthermore, if
the DNS2000 is brought directly from a cold environment into a warm one, moisture may
condense inside it. This, in itself, will not cause damage, but may cause electrical shorting. This
could damage the DNS2000, and even cause danger to life. Always allow the DNS2000 to reach
ambient temperatures naturally before connecting the mains power.
Mounting and ventilation
You should place the DNS2000 on a flat, stable surface or mount it in a standard 19” equipment
rack. Use the supplied rubber feet to avoid scratching the surface, or the rackmounting
accessories, as appropriate. Do not subject the DNS2000 to strong sunlight, excessive dust,
mechanical vibration or periodic shocks. The unit is not susceptible to excessive heat build-up,
but should be installed away from heat sources such as radiators and audio devices that
produce large amounts of heat.
Power sources
The DNS2000 features a universal power supply that will work safely on any mains supply in the
range 85V to 260V, 50Hz or 60Hz AC only. The unit should always be grounded (earthed), and
you should route power cables so that they will not be walked on or pinched.
Connections
Turn off the power to all equipment before making any connections.
Cleaning
Clean the DNS2000 only with a dry cloth. Never use abrasive pads or liquid cleaners such as
alcohol or benzene.
Damage requiring service
The DNS2000 contains no user-serviceable parts and should on no account be opened or
dismantled by unauthorised personnel. It should be returned to qualified service agents when it
has been exposed to liquids, when it fails to function correctly, when it has been dropped, or
when the case is damaged.
