Manufacturer's notes
Energy Star
The Siemens Nixdorf multiscan color monitor MCM 1755
NTD is designed to conserve electricity by dropping to less
than 15 W when it goes into suspend mode and to less than
5 W when it goes into OFF mode. With this new power
management the MCM 1755 NTD qualifies for the U.S.
Environmental Protection Agency's (EPA) Energy Star
Computers award.
The EPA estimates that computer equipment uses 5 percent of all business
electricity and it is growing rapidly. If all desktop PCs and peripherals enter a
low-power mode when not in use, the overall savings in electricity could amount to
$ 2 billion annually. These savings could also prevent the emission of 20 million
tons of carbon dioxide into the atmosphere - the equivalent of 5 million
automobiles.
The EPA, as a matter of policy, seeks only to promote energy efficiency and does
not endorse any particular company or its products.
CE certificate
This device complies with the requirements of the EEC directive
89/336/EEC "Electromagnetic compatibility" and 73/23/EEC "Low
voltage directive" with amending directive 93/67/EEC.
Note on RFI suppression
All other devices connected to this product must have RFI suppression in
accordance with EEC directive 89/336/EEC. Products meeting these requirements
are accompanied by a certificate issued by the manufacturer and carry the
CE symbol.
In Germany, products not complying with these requirements can be operated only
after a special authorization has been granted by the BZT.
A26361-K472-Z100-2-5E19 English - 5
Color monitor MCM 1755 NTD
Note on X-ray radiation

Notes on ergonomic color adjustment
If you select colors for the display in your application programs, take note of the
information below.
The primary colors blue and red on a dark background do not produce the
minimum required contrast of 3:1 and are therefore not suitable for continuous text
and data entry.
When using several colors for characters and background and giving the primary
colors full modulation, you can obtain very suitable color combinations (see the
following table):
Back-
ground Character color
color black white purple blue cyan green yellow red
black + + - + + + -
white + + + - - - +
purple + + - - - - -
blue - + - + - + -
cyan + - - + - - -
green + - - + - - -
yellow + - + + - - +
red - +----+
+ Color combination very suitable; light background colors are only suitable for
devices which are operated with a refresh rate of at least 75 Hz.
- Color combination not suitable because color locations are too close together,
thin characters are not identifiable or rigorous focusing is demanded of the
human eye.
20 - English A26361-K472-Z100-2-5E19
Color monitor MCM 1755 NTD
Cleaning the monitor
Always pull out the power plug before you clean the monitor.
!
Do not clean any interior parts yourself, leave this job to a service
technician.
Do not use any cleaning agents that contain abrasives or may corrode
plastic.
Ensure that no liquid will run into the system.
Ensure that the ventilation areas of the monitor are free.
Wipe the monitor housing with a dry cloth. If the monitor is particularly dirty, use a
cloth which has been moistened in mild domestic detergent and then carefully
wrung out.
Transporting the monitor
When transporting the monitor ensure that it is not exposed to strong
!
magnetic fields.
Transport the monitor with care and only in its original packaging or
another corresponding packaging fit to protect it against knocks and jolts.
Above all, never drop the monitor. If the CRT is damaged, there is a
danger of implosion!
