General Information 0
Safety Information 0
The DHHS regulations have been met in this monitor under the following circumstances:
• No components may be replaced on the board level and no adjustments (potentiome-
ters) may be made in the power supply (with high voltage)!
Exception: when a modification or upgrade is initiated by an AUI, etc.
• Line power is present at the heat sink of the power supply to the frame, there is a risk of
contact if the monitor is opened, even in the standby mode!
WARNING
When handling the monitor, there is a risk of implosion of the picture tube!
If not observed, death or serious bodily injury can occur.
¹ The required protective clothing must be worn.

Product-specific Remarks 0
Remarks Regarding the Monitor 0
• The SIMOMED HM monitor recognizes the particular TV scan norm (only H scan norm)
and automatically switches to it. If a norm is used that is not programmed, the monitor
automatically recognizes this norm, and it may be necessary to adjust the geometry
and contrast/brightness. The "next" time, it will recognize this norm and will assign the
parameters that have been set for it.
• If adjustments have to be carried out, they must be carried out in all the scan norms that
are programmed for the particular image system/TV.
Reason: separate EEPROM values are allocated for each norm.
• Repair of the monitor is made beginning / since February 1, 2001 only by completely re-
placing the monitor!
• Monitor adjustment is made using a laptop computer
(Basic adjustments can be made using the front key panel (Basic Adjustments without
the PC / p. 8).
• The power input is set up for 110 - 230 V +/- 10% 50/60 Hz.
• Occasional high voltage surges =< 2sec. with image disturbances are admissible.
• Cut off:
Approx. 15 min. after switching power ON, and then every 12 hours, the monitor
performs an automatic cut-off adjustment. This cut-off adjustment compensates for
aging of the picture tube. During the cut off-adjustment, approx. every 2 sec., the image
brightness changes.
• Pass-through output for BAS signal.
The SIMOMED HM does not have a BAS pass-through output.
However, if necessary a T-adapter can be used at the BAS input for BAS forwarding. If
this is done, the terminal resistor must be opened (Replacing the Firmware / p. 11).
NOTE
For video norms of > 60 Hz image refresh rate, image quality problems occur when the BAS signal is channeled through. Video
norms of 50/60 Hz image refresh rate must have connection cables
that are as short as possible for the throughput mode. If there are
problems, a video distributor amplifier must be used.
Adjustment 0
• Adjustment values, as well as the adjustment procedure are handled only over the help
texts in the service user interface.
Selection is made in the service user interface under <Help>-<Service>.

6 General Remarks
Troubleshooting / Repair / Replacement 0
Beginning / since February 2001, the monitor is only replaced completely when there is a
malfunction.
• Every defective monitor must be returned with an exact description of the malfunction!
• Without a description of the malfunction, sporadic and/or temperature-related effects or
even system-dependent causes almost never can be found.
NOTE
WARNING
If a middle monitor in an MTS 1 / 3 / 6 needs to be replaced, the position of the monitor to the rear longitudinal strut can be changed
so that the monitor can be replaced without “spending extra time”
on it.
However, the document
for MTS 1/3/6 (AX52-X01.812.01 / Transverse Strut Horizontal Rota-
tion at the Bottom)
for MTS 6, upper traverse (AX52-X01.812.01 / Turning the Top Hor-
izontal Transverse Strut)
must be observed!
Increased risk of injury!
If the installation document is not observed, the traverse can fall
and crushing can occur.

Front Key Panel Operation 0
The following adjustments can be made without using the Service PC by using the front
panel keys, as long as these keys have been enabled by the service user interface.
Beginning with firmware Version 01.40, a cutoff can be started when the service key is
blocked (status when shipped) by pressing the service key.
It is necessary that the time requirement (20 min. after switching on power) be met.
• The adjustment functions can be keyed through, one after the other, using the service
key; the parameters can be changed using the keys for brightness and contrast +/-.
• If the adjustment mode has been selected with the service key and no entry is made in
approx. 30 sec., the symbol in the 7-segment display begins to blink. While it is blinking, or even before this, the old value can be reset by briefly selecting the power key.
When the symbol blinks for approx. 5 sec., the 7-segment display goes out and the new
parameters are stored as default parameters!
• If the adjustment range is exceeded, the top or bottom lines in the 7-segment display
will blink.

For adjustment and selection, see: (Brightness / Contrast Adjustment using the Front but-
tons or in the SSW / p. 21).
NOTE
The video amplifier adjustment must be adjusted prior to adjusting
the brightness / contrast, see (Adjusting the Video
Amplifier / p. 18).
If an adjustment of brightness / contrast must / should be made
while the front panel keys are blocked, beginning with FW 1.74
(shipments beginning approx. mid ‘99), this can be done as follows:
By simultaneously pressing the brightness + and brightness keys 4x in sequence, key blocking can be deactivated or activated.
This means that the values can be changed without a laptop.
Power Down and Ambient Light Sensor 0

Adjusting the Video Amplifier 0
General Remarks 0
• The maximum brightness and the maximum contrast are adjusted in the window (Ad-
justment => Video Amplifier). Adjustment can be made to these set values using the
front control knobs (brightness/contrast) or by means of the ambient light sensor, when
activated.
• The settings are always performed in the 0% field for brightness and in the 100% field
for contrast. The exception is with Magic View; see the value table.
• Test image
- AXIOM Artis ......
We use the “Siemens” test pattern (it has larger measuring fields than the SMPTE
test pattern).for H/C adjustment.
Select zoom to magnify the fields again. Move the corresponding field (0% - 100%) to
approx. the center of the image. Note: The hand symbol may not be in the measuring
field (incorrect measurement)!
Important:
The window for the test pattern must always be fully opened in AXIOM ARTIS.. If the
window values are/were changed, the “Patient” closed, the “new” values are saved!
Open values:
WC 2048
WW 4094
- The adjustment can be performed with the test image for the particular digital system
or with the monitor multinorm test box. If the test box is used, pay attention to the correct “Norm” as well as to the BAS values!
- HICOR / ACOM
If the SMPTE test pattern is used, the test point for the black value is at the right edge
of the screen, outside the SMPTE test image.
- Multistar TOP
Use the black / white test image.
- Multistar KK
If the SMPTE test pattern is used, the zoom function must be used to obtain a
sufficiently large black area for the measurement.
- Monitor Mulitnorm Testbox.
In the list box, the corresponding system (e.g. HICOR, ... ) must be selected.
The black/white test image must be used for the adjustment.
If HICOR is selected (also general) pay attention to the video level: change the
B-signal to 650mV and the A-signal to 50mV (with 1V BAS).
• Warm-up phase
- The monitor must be left on for at least 20 minutes (warm-up behavior of the picture
tube). If the time is too brief, it will not be possible to make a selection in the screen.

Brightness / Contrast Adjustment using the Front buttons or in the SSW
Tab. 1 Front buttons
• Using the front buttons, or if if the
front buttons are blocked, in the SSW
under:
=> Configuration => Brightness and
Contrast
the final brightness / contrast values
are adjusted. For the current values,
see the applicable IQAP/IQ.
- Set the Contrast minimum slider to
0 (not used).
- Using the slider for Maximum background, set the value for brightness from the table (Tab. 3 / p. 22).
- Using the slider for Maximum contrast, set the value for contrast from
the table (Tab.3/p.22).
- If necessary,repeat both adjustments.
Bypass Adjustment
Tab. 2 Bypass
• If a bypass mode is being used at the par-
ticular system (as a rule, this is the emergency mode), the brightness / contrast
values for this mode must be adapted to
the “Normal mode”.
This is done in the SSW under:
Fig. 8: int. Brightness / Contrast
=> Adjustment => Video amplifier => Bypass
- Insert the TV dynamic test.
Fig. 9: Bypass Window
In the “Normal mode”, measure the luminous intensity values in the 2L and 5R
fields using the Mavo monitor and make
a note of the values.
- In the “Bypass mode”, use the slider for
Maximum background to set the value in
the 5R field and the slider for Maximum
contrast to set the value in the 2L field to
the values that were noted.
- If necessary, repeat both adjustments.
