If you have VESA DPM compliance display card 
or software installed in your PC, the monitor can 
automatically reduce its power consumption when 
not in use. If an input from a keyboard, mouse or 
other input device is detected, the monitor will 
wake up automatically. The following table shows

Federal Communications Commission (FCC) 
Notice (U.S. Only)
  
This equipment has been tested and found 
to comply with the limits for a Class B digital 
device, pursuant to Par t 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 and 
used in accordance with
the instructions, may cause harmful 
interference to radio communications. 
However, there is no guarantee that 
interference will not occur in a par ticular 
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 tr y to correct the 
interference by one or more of the following 
measures:
Reorient or relocate the receiving antenna. 
 •
  Increase the separation between the 
 •
equipment and receiver. 
  Connect the equipment into an outlet on 
 •
a circuit different from that to which the 
receiver is connected. 
  Consult the dealer or an experienced radio/
 •
TV technician for help.
  Changes or modifications not expressly 
approved by the par ty responsible for compliance 
could void the users authority to operate the 
equipment.
Use only RF shielded cable that was supplied with 
the monitor when connecting this monitor to a 
computer device. 
To prevent damage which may result in fire or 
shock hazard, do not expose this appliance to rain 
or excessive moisture.

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 rooms electrical 
installation should have a reser ve shor t-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/T-42107 
and PN-89/E-06251.

Ergonomie Hinweis (nur Deutschland)
Der von uns geliefer te Farbmonitor entspricht den 
in der Verordnung über den Schutz vor Schäden 
durch Röntgenstrahlen festgelegten Vorschriften. 
Auf der Rückwand des Gerätes befindet sich 
ein Aufkleber, der auf die Unbedenklichkeit der 
Inbetriebnahme hinweist, da die Vorschriften über 
die Bauar t von Störstrahlern nach Anlage III ¤ 5 
Abs. 4 der Röntgenverordnung erfüllt sind. 
Damit Ihr Monitor immer den in der Zulassung 
geforder ten Wer ten entspricht, ist darauf zu 
achten, daß 
Reparaturen nur durch Fachpersonal 
1. 
durchgeführ t werden. 
nur original-Ersatzteile verwendet werden. 
2. 
bei Ersatz der Bildröhre nur eine bauar tgleiche 
3. 
eingebaut wird. 
Aus ergonomischen Gründen wird empfohlen, 
die Grundfarben Blau und Rot nicht auf dunklem 
Untergrund zu verwenden (schlechte Lesbarkeit 
und erhöhte Augenbelastung bei zu geringem 
Zeichenkontrast wären die Folge). 
Der arbeitsplatzbezogene Schalldruckpegel nach 
DIN 45 635 beträgt 70dB (A) oder weniger.
