SAFETY INSTRUCTIONS
WARNINGS AND PRECAUTIONS
KNOW THESE SAFETY SYMBOLS
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER
SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
This symbol indicates high voltage is present inside. It is dangerous to make any kind of contact with any
inside part of this product.
This symbol alerts you that important literature concerning operation and maintenance has been included
with this product.
Caution: FCC/CSA regulations state that any unauthorized changes or modifications to this equipment may void the user’s
authority to
operate it.
Caution: To prevent electric shock, match the wide blade of plug to the wide slot, and fully insert the plug.
Attention: Pour éviter les chocs électriques, introduire la lame la plus large de la fiche dans la bome correspondante de la prise et
pousser jusqu’au fond.
TO PREVENT DAMAGE WHICH MAY RESULT IN FIRE OR ELECTRIC SHOCK HAZARD, DO NOT EXPOSE THIS
APPLIANCE TO RAIN OR MOISTURE.
The Socket-outlet shall be installed near the apparatus and shall be easily accessible.
Read and follow these instructions when connecting and using your computer monitor:
z Unplug the monitor if you are not going to use it for an extensive period of time.
z Unplug the monitor if you need to clean it with a slightly damp cloth. The screen many be wiped with a dry cloth
when the power is off. However, never use alcohol, solvents or ammonia-based liquids.
z Consult a service technician if the monitor does not operate normally when you have followed the instructions in
this manual.
z The casing cover should be opened only by qualified service personnel.
z Keep the monitor out of direct sunlight and away from stoves or any other heat source.
z Remove any object that could fall into the vents or prevent proper cooling of the monitor’s electronics.
z Do not block the ventilation holes on the cabinet.
z Keep the monitor dry. To avoid electric shock, do not expose it to rain or excessive moisture.
z If turning off the monitor by detaching power cable or DC power cord, wait for 6 seconds before attach the power
cable or DC power cord for normal operation.
z To avoid the risk of shock or permanent damage to the set do not expose the monitor to rain or excessive
moisture.
z When positioning the monitor, make sure the power plug and outlet are easily accessible.
z IMPORTANT: Always activate a screen saver program during your application. If a still image in high contrast
remains on the screen for an extended period of time, it may leave an ‘after-image’ or ‘ghost image’ on the front of
the screen. This is a well-known phenomenon that is caused by the shortcomings inherent in the LCD technology.
In most cases the afterimage will disappear gradually over a period of time after the power has been switched off.
Be aware that the after-image symptom cannot be repaired and is not covered under warranty.

POLISH CENTER FOR TESTING AND CERTIFICATION NOTICE
The equipment should draw power from a socket with an attached protection circuit (a three-prong socket). All equipment that
works
together (computer, monitor, printer, and so on) should have the same power supply source.
The phasing conductor of the room’s electrical installation should have a reserve short-circuit protection device in the form of a fuse
with
a nominal value no larger than 16 amperes (A).
To completely switch off the equipment, the power supply cable must be removed from the power supply socket, which should be
located near the equipment and easily accessible.
A protection mark “B” confirms that the equipment is in compliance with the protection usage requirements of standards PN-93/T42107 and PN-89/E-06251.

INFORMATION FOR UK ONLY
WARNING - THIS APPLIANCE MUST BE EARTHED.
Important:
This apparatus is supplied with an approved moulded 13A plug. To change a
fuse in this type of plug proceed as follows:
1. Remove fuse cover and fuse.
2. Fit new fuse which should be a BS 1362 5A,A.S.T.A. or BSI approved type.
3. Refit the fuse cover.
If the fitted plug is not suitable for your socket outlets, it should be cut off and an
appropriate 3-pin plug fitted in its place.
If the mains plug contains a fuse, this should have a value of 5A. If a plug
without a fuse is used, the fuse at the distribution board should not be greater
than 5A.
Note: The severed plug must be destroyed to avoid a possible shock hazard
should it be inserted into a 13A socket elsewhere.
How to connect a plug
The wires in the mains lead are coloured in accordance with the following code:
BLUE - “NEUTRAL” (“N”)
BROWN - “LIVE” (“L”)
GREEN & YELLOW - “EARTH” (“E”)
1. The GREEN AND YELLOW wire must be connected to the terminal in
the plug which is marked with the letter “E” or by the Earth symbol or
coloured GREEN or GREEN AND YELLOW.
2. The BLUE wire must be connected to the terminal which is marked with the
letter “N” or coloured BLACK.
3. The BROWN wire must be connected to the terminal which marked with the
letter“L” or coloured RED.
Before replacing the plug cover, make certain that the cord grip is clamped over
the sheath of the lead - not simply over the three wires.
