 Important notes 
Important notes 
! 
In this chapter you will find information regardi ng safety which is essential to take note of 
with your monitor. 
Safety notes 
This device complies with the relevant safety  regulations for data processing equipment, including 
electronic office machines for use in an office  environment. If you have any questions, contact your 
sales outlet or our Service desk. 
●   The display surface of the LCD monitor is  sensitive to pressure and scratches. You should 
therefore be careful with the display surface  so as to avoid lasting damage (Newton rings, 
scratches). 
●   If the device is brought into the installation  site from a cold environment, condensation can 
form. Before operating the device, wait until it  is absolutely dry and has reached approximately 
the same temperature as the installation site. 
●   To ensure sufficient ventilation, the intake  and exhaust air openings of the monitor must never 
be blocked. 
●   The monitor automatically sets itself to a mains voltage in the range of 100 V to 240 V. Ensure 
that the local mains voltage lies within these limits. 
●  Ensure that the power socket on the device or  the grounded mains outlet is freely accessible. 
●  The ON/OFF switch does not disconnect the devic e from the mains voltage. To completely 
disconnect the mains voltage, remove the power plug from the socket. 
●   The monitor is equipped with a power cable that complies with safety standards. 
●  Lay all cables so that nobody can stand on them  or trip over them. When attaching the device, 
observe the relevant notes in the Connecting the monitor chapter. 
●   Wenn Sie eine andere als die mitgelieferte  Datenleitung verwenden, achten Sie darauf, dass 
die Leitung ausreichend abgeschirmt ist. CE-Konf ormität sowie eine optimale Bildqualität 
werden nur mit der mitgelieferten Datenleitung gewährleistet. 
●   If you use a different data cable from the one  supplied, ensure that it is adequately shielded. 
CE conformance and optimum picture quality  are guaranteed only if you use the data cable 
supplied. 
●   No data transfer cables  should be connected or disconnec ted during a thunderstorm. 
●  Make sure that no objects (e.g. jewellery chai ns, paper clips, etc.) or liquids get inside the 
device (danger of electric  shock, short circuit). 
●  The device is not waterproof! Never immerse the device in water and protect it from spray 
water (rain, sea water). 
●  In emergencies (e.g. damaged casing, elements or  cables, penetration of liquids or foreign 
matter), switch off the unit, disconnect the power plug and contact your sales outlet or our 
Service desk.

special waste. The screen background lighting c ontains mercury. You must observe the 
applicable handling and disposal safety  regulations for fluorescent tubes. 
●  Only qualified technicians  should repair the device. Unaut horised opening and incorrect repair 
may greatly endanger the user (electric shock, fire risk). 
●   Use a screen saver with moving images and acti vate the power management for your monitor 
to prevent still images from burning in. 
●   The screen may only be operated in the wide format (0° landscape mode). Turning with a 
swivel arm or wall bracket mounted is not permitted. 
●  Store this manual close to the device. If y ou pass the device on to third parties, you should 
pass this manual on with it.

different surface coatings and finis hes used on furniture, it is possible that the feet of the device 
could mark the surface they stand on. 
Power cable 
To guarantee safe operation, use the cable supplied. Us e the following guidelines if it is necessary to 
replace the original cable set. 
●   The female/male receptacles of the cord set must meet IEC60320/CEE-22 re\
quirements. 
●  The cable has to be HAR-certified or VDE-ce rtified. The mark HAR or VDE will appear on the 
outer sheath. 
●   For devices which are mounted on a desk or tabl e, type SVT or SJT cable sets may be used. 
●  The cable set must be selected according to the rated current for your device. 
●  If necessary, replace the original power c able with a regular grounded 3-core mains lead. 
Transport 
●  Transport the monitor with care and only in  its original packaging or another corresponding 
packaging fit to protect it against knocks and jolts. 
●   Never drop the LCD monitor (danger of glass breakage).
