1.5. Monitor Connection
Make sure that the monitor is disconnected from mains and the power switches of the com-
puter and all attached devices are turned off before connecting the monitor.
-- Connect the signal cable plug to the videocontroller connector at the back of the computer.
-- Tighten the screws on the plug by hand.
-- Connect the power cord first to the monitor and then to a grounded power outlet.
-- Do not use any adapter when connecting signal cable to your computer.
-- Do not extend the signal cable with extension lead. The DDC signals will not accept extended
cable.
--- Display controller must be compatible for External +5 V, In SMK001 E---version External +5 V is
not necessary but the monitor works also with it

2. Site Preparation
2.1. Location
This Monitor is designed for normal office conditions. It is equipped with own power supply. It is not
to be serviced or repaired on site
2.2. Troubleshooting
Local service facilities should perform simple maintenance such as trimming. More advanced main-
tenance and repair that requires replacement of components which in turn requires testing and re-
trimming should be carried out in a central workshop.

Check that the power cord is correctly connected to the monitor and to the power
outlet. If the monitor is powered through the computer, check that the computer is
switched on with the mains switch. Use a desk light, for example, to verify that
current is connected to a power outlet. If no electricity is connected to the outlet,
call an electrician.

Switch off the monitor and the computer. Remove the signal cable from the
computer. Switch on the monitor using the power switch. If the Selftest error menu
appears on the screen, it is evident that the monitor functions correctly and
the problem is caused by an error in other parts of the system.
Check the signal cable’s connection pins. If the pins are slightly distorted,

fects If colour defect is repeated without the monitor having been moved, it is possible
that the monitor is influenced by a strong magnetic interference field (near to
a high power cable, for example). Try to find a better location for the monitor or
the interference source. Note that another monitor placed too near (less than
30 cm.) may also generate interference in the picture.
Picture has strong colour
defect,
Switch off the monitor and the computer. Remove the signal cable from the
computer. Switch on the monitor using the power switch.Check the colour of the
Red, Green and Blue bars. If they have pure colours, the fault is not in the monitor.
Check signal cable connectors and the computer. If the menu itself and the colour
bars are discoloured, the monitor is obviously damaged.
