Note
- the product-specific safety notes in these instructions,
- the general safety information in the document
TD00-000.860.01...
and
- the safety information in accordance with ARTD Part 2.
Non-compliance can lead to death, to injuries or to material
damage.
Electrical safety!
Non-compliance can lead to severe injuries and even death and to
material damage.
After opening the cover panels, the parts under voltage are acces-
sible. To avoid risks, switch off power to the system prior to open-
ing cover panels. Pull out the power supply plug.
If an uninterruptible power supply (UPS) is installed in the sys-
tem, the power supply of the UPS must be switched free of volt-
age in addition or the voltage output plug must be pulled out.
If work has to be performed under electrical voltage, the general
safety information according to TD00-000.860.01... must be com-
plied with.
Electrical voltage!
Non-compliance can lead to material damage.
When working on the system, ESD regulations must be observed.

Safety Information, Mechanical 1
Danger of injuries on mechanical parts!
Non-compliance can lead to slight to medium injuries, especially
of the hands.
The C-arm of the system is manufactured from carbon fiber com-
posite material (CFK). In the case of damage to the carbon fiber
structure, for example caused by collision or by cutting or scrap-
ing tools, individual carbon fibers or carbon fiber bundles can
stand out and on contact cause injuries to the skin or penetrate
into the tissue of the hand.
Before starting work on the C-arm, make sure that there is no
damage to the carbon fiber structures (visual inspection).
If smaller superficial damage is detectable in the painted area or
in the area of the running surface edges of the C-arm, wear work-
ing gloves and remove any projecting carbon fibers. Then care-
fully rub the damaged places flat with fine emery cloth and close
the damaged surface with paint. A spray paint in the color of the
C-arm can be used for this purpose (See Service Tool Catalogue).
Remove any carbon fibers lying in the C-arm profile with a damp
sponge or cloth.
If greater damage to the carbon fiber structure indicating general
or large-scale destruction of the carbon fiber structure (e.g. crack
formation or flaked off places in the running surfaces with torn
carbon fibers) can be detected, then replace the C-arm.
Danger of injuries on mechanical parts!
Non-compliance can lead to slight to medium injuries, especially
of the hands.
After covers are opened, parts such as flat plugs, threaded bolts,
cut-off cable ties and edges of components can be touched
which, if care is not taken, can cause crushing, scrapes and cuts
to the skin, particularly to the hands.
Perform the particular work steps with special care and attention
to detail.
If needed, wear working gloves.

Safety Information, Risk of Infection 1
Danger of injuries on mechanical parts!
Non-compliance can lead to slight to medium injuries, especially
of the hands.
Before starting service or maintenance work, check the system by
a visual inspection for mechanical safety defects which in the
case of inattention could lead to injuries. For example, projecting,
bent or broken parts / covers, damaged plugs or cables.
Remove existing safety defects by replacement or repair of the
damaged parts.
Perform the particular work steps with special care and attention
to detail.
If needed, wear working gloves.
Danger of burns on hot parts or components!
Non-compliance can lead to slight to medium injuries, especially
of the hands.
After opening the cover panels, parts and components (e.g.
power components, cooling units, electromagnetic brakes) are
accessible that can have temperature of > 50C during operation.
To avoid burns, switch the system off prior to touching parts or
components and let them cool at least 5 minutes.
Danger of infections due to pathogens!
Non-compliance can lead to severe injuries and even death.
This product can be contaminated by infected blood or other
bodily fluids.
Avoid all contact with blood or other bodily fluids!
Strictly observe the safety information in ARTD-002.731.37...
regarding prevention of infectious diseases during customer ser-
vice calls.

Safety Information, Radiation 1
X-ray radiation!
Non-compliance can lead to illnesses, irreversible damage to
body cells and the genotype, severe injuries and even death.
In work on the system in which radiation must be released, the
radiation protection directives and the rules for radiation protec-
tion according to ARTD 02.731.02 must be complied with.
Please note:
- Use available radiation protection devices.
- Wear radiation protection clothing (lead apron).
- Keep your distance from the radiation source as large as possible.
- Release radiation only if necessary.
- Set radiation activity as low as possible.
(Low kV and mAs values, short radiation time)
- Release radiation for as short a time as possible.
Checks in which radiation must be released are identified by the
radiation warning symbol.

Protective conductor resistance test information 1
Observe the instructions in the safety rules for installation and repair
(ARTD-002.731.17 ...).
The protective conductor resistance must be measured after every intervention in the
system.
However, documentation of the measured values is required only during periodical
safety checks.
If parts / components that can decisively influence the protective conductor resistance are
replaced (e.g. replacement of the mains cable, replacement of the ON/OFF assembly,
replacement of multi-core connection cables, which also create the protective conductor
connection between parts of the system (e.g. monitor cable or C-arm cable)), or if protec-
tive conductor connections have been repaired, then the protective conductor resistance
must be measured. The values must be documented and assessed in the protective con-
ductor resistance report.
The measurement must be made according to DIN VDE 0751, Part 1 (see ARTD Part 2).
In this case the protective conductor resistance in the normal operating condition to all
conductive touchable parts of the system must be measured.
Make sure that control cables or data cables between the components of the system do
not imitate any protective conductor connection.
During the measurement the power cable and additional connection cables which also
create the protective conductor connection between parts of the system (e.g. monitor
cable between basic unit and monitor trolley) must be moved section by section to detect
broken conductors.
The protective conductor resistance may not exceed 0.2 Ohms.
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding mainte-
nance procedures or safety checks.
A sudden or unexpected increase of the measured values, even if
the limit value of 0.2 ohms is not exceeded, indicates errors in the
protective conductor connections. (Protective conductor or con-
tacts).

Preparations 1
•Attach and center the center cross on the I.I. (Fig. 4).
•Select survey format.
•Select KV mA curve plateau HC1.
•Attach and center the small (1cm3) dose measurement chamber of the dose
measurement device (Dali, Nomex ...) or the semiconductor detector (Diados) onto the
image intensifier (Fig. 5).
•Release fluoroscopy briefly, adjusting the iris on the radiation field to a format of
approximately 15 cm.
•Do not make any further adjustments to the iris.
•Record the diameter (Fig. 6) of the octagonal area of the radiation field.
•Remove the center cross.
•Select kV STOP and enter 70 kV.
Dose measurement 1
•Press the >0< key twice to reset the area dose product on the Siremobil monitor to 0 .
•Reset the dose measurement device (Dali, Nomex ...) to 0 .
•Release fluoroscopy several seconds. The measured dose KEshould be high enough
that the uppermost measurement range of the dose measurement device is utilized fully;
if necessary, reset the area dose product display on the Siremobil and the dose
measurement device and repeat the measurement with a different fluoroscopic time.
•Record the measured dose.
•Record the area dose product displayed on the Siremobil monitor (FDPa).
Calculating the area dose product 1
•To calculate the measured area dose product :
(measured area dose product FDPg) = (measured dose KE) * (diameter)2 * 0.829
Evaluation 1
Calculate the deviation between the measured area dose product and the displayed area
dose product:
The deviation must be < 0.3 .
Deviation = [(displayed area dose product FDPa) - (measured area dose product FDPg) ]
/ (measured area dose product FDPg)
For deviations > 0.3 , the area dose product measurement device must be replaced.
The radiation field must cover the entire area of the dose mea-
surement chamber respectively the semiconductor detector of the
dose measurement device.
