For U.K. Customers
THIS PRODUCT IS SUPPLIED WITH A TWO PIN MAINS
PLUG FOR USE IN MAINLAND EUROPE. FOR THE U.K.,
PLEASE REFER TO THE NOTES ON THIS PAGE.
Note:
Electrical Connection
Your monitor requires an electrical supply of 240 volts - 50 Hertz and should
be protected by a 5 amp fuse. Your equipment is supplied with a plug
incorporating a 5 amp fuse fitted to the mains lead. If the plug that is fitted
to the equipment is not suitable for your socket outlet, it must be cut off and
the appropriate plug fitted. The cut off plug should be disposed of, do not
insert it into a 13 amp socket to prevent the hazard of electric shocks. With
plugs not incorporating a fuse, the circuit must be protected by a 5 amp fuse.
Warning: This equipment must be earthed.
Important
Your equipment is supplied with a mains lead, the wires of which are
coloured in accordance with the following code: Green and Yellow - Earth,
Blue - Neutral, Brown - Live.
Green & Yellow
to Earth
Blue to Neutral
Brown to Live
Fuse
Cord Clamp

As the colours of the wires in your mains lead in this equipment may not
correspond with the markings identified with the terminals of your plug,
proceed as follows:
The wire which is coloured Green and Yellow must be connected to the
terminal in the plug which is marked with the letter E or by the symbol or
coloured Green or Green and Yellow.
The wire which is coloured Brown must be connected to the terminal which
is marked with the letter L or coloured Red.
The wire which is coloured Blue must be connected to the terminal which
is marked N or coloured Black.
The plug moulded on to the cord incorporates a fuse. For replacement, use
a 5 amp BS1326 fuse. Only ASTA approved fuses should be used. The fuse
cover / carrier must be refitted when changing the fuse. In the event of
losing the fuse cover / carrier, the plug must not be used until a replacement
has been obtained from your nearest electrical stockist and fitted. The
colour of the fuse cover / carrier is that of the coloured marks on the insert
in the base of the plug.

Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy, and if not installed in accordance with the
instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on? the user is encouraged to try to correct the
interference by one or more of the following measures:
a Reorient or relocate the receiving antenna.
a Increase the separation between the equipment and receiver.
l Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
e Consult the dealer or an experienced radio/TV technician for help.
Warning: A shielded-type power cord is required in order to meet FCC
emission limits and also to prevent interference to the nearby radio and
television reception. It is essential that only the supplied power cord be
used.
Use only shielded cables to connect I/O device to this equipment.
You are cautioned that changes or modifications not expressly approved by
the party responsible for compliance could void your authority to operate
the equipment.
DOC compliance notice
This digital apparatus does not exceed the Class B limits for radio noise
emissions from digital apparatus as set out in the Radio Interference
Regulations of the Canadian Department of Communications.
DOC avis de conformation
Le present appareil numerique n’cmet pas de bruits radioelectriques
depassant les limites applicables aux appareils numeriques de la Class B

Low Radiation
Following the trend in the computer market toward low radiation, this
equipment has been tested and found to comply with Swedish regulatory
agency guidelines.
Research has shown that magnetic field emissions from computer monitors
may pose a very real health hazard to users, and this has become a great
concern to many people. Consequently, we are offering this low- radiation
display in response to the magnetic field emission issue.
The Swedish guidelines defines a level of induction and strength permissible
for magnetic field emissions. Magnetic field emissions for the equipment is
significantly lower than the Swedish guideline of 25 nT.
