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.
¹ Installation Instructions, AX52-X01.812.01.... absolutely
must be observed.
Test Equipment and Aids 0
• Laptop with the Windows operating system.
• Serial interface cable (0 modem cable).

8 Basic Adjustments without the PC

3-
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.
