On-Screen Messages
The
ECOMO 21S99
can take care of itself. The following on-screen message will appear
if there is no sync signal:
It may however be that the signal frequency is outside the permitted range. The message
will appear in the second window if this is the case.
The number following ‘INPUT’ indicates which monitor input is receiving no signal or the
wrong signal. The message will alternate INPUT ‘1’ (HD15) and INPUT ‘2’ (5BNC) if both
monitor inputs are receiving no signal or the wrong signal.
Self-Diagnosis Function of the Monitor
The ECOMO 21S99 is equipped with a self-diagnosis function. The screen will remain
blank and the power indicator will either light up green or flash orange if there is a prob-
lem with the monitor or the graphics board.
If the Power Indicator Lights Up Green
Firstly switch off any computers connected or disconnect the plugs from the graphics
inputs. Now press button
쏡
for approx. 2seconds.
All four color bars will now appear (white, red green blue) on screen if the monitor is
working properly. If not, then the monitor is faulty. You should contact ELSA-Support in
this event (

If the Power Indicator Flashes Orange
Switch off the monitor. The monitor is faulty if the indicator continues to flash as before.
Make a note of the flash interval and inform ELSA Support (
