Sirona Dental Systems GmbH 1 Warning and Safety Notes
1 Warning and Safety Notes
Labeling of warning and safety information In order to prevent injury to persons and damage to the
equipment you must also read the warning and safety
notes given in these Operating Instructions. These are
emphasized with CAUTION and WARNING.
Symbols used Observe accompanying documents
(on name plate)
Intended use This unit has been designed for use in creating pano-
rama radiographic exposures.
This unit must not be used in areas where there is a risk
of explosion.
Maintenance and repair As manufacturers of electromedical equipment we can
assume responsibility for safety-related performance of
the equipment only if maintenance and repair are carried out only by us or agencies we have authorized for
this purpose, and if components affecting safe operation
of the unit are replaced with original spare parts.
We suggest that you request a certificate showing the
nature and extent of the work performed from those who
carry out such work; it must contain any changes in rated
parameters or working ranges (if applicable), as well as
the date, the name of the company and a signature.
Modifications to the system Modifications to this system which could impair the
safety of operators, patients or third persons are prohibited by legal provisions!
For reasons of product safety, this product may be
operated only with original Sirona accessories or accessories manufactured by third parties expressly approved
by Sirona. The user is responsible for dangers resulting
from the use of non-approved accessories.
If any devices not approved by Sirona are connected,
they must comply with the applicable standards:
IEC 60950 for information technology equipment (e.g.
PCs), and IEC60601-1 for medical electrical equipment.
Ventilation slots Under no circumstances may the ventilation slots on the
unit be covered, since otherwise the air circulation will be
obstructed.
Do not spray disinfectants or other similar products into
the ventilation slots.
X-rays of patients X-rays of patients must be taken only when the system
works without errors.
The system may only be operated by skilled or properly trained personnel.

1 Warning and Safety Notes Sirona Dental Systems GmbH
The movements of the unit must not be obstructed by
physical constitution nor clothing, dressings, wheelchairs or hospital beds!
Do not leave the patient unattended in the unit.
Electromagnetic compatibility (EMC) Medical electrical devices are subject to special precau-
tionary measures regarding EMC. They must be
installed and operated as specified in the document
"Installation Requirements".
Information on avoiding, recognizing and eliminating
unintended electromagnetic effects: The ORTHOPHOS
Plus acquisition unit is a Class B device (classified
according to CISPR 11, EN 60601-1-2: 2001 based on
IEC 60601-1-2). This system may be operated in a residential area.
Portable and mobile HF communication devices can
influence medical electrical equipment. The use of
mobile telephones in the practice or hospital area therefore must be prohibited.
Precautionary measures when switching on the
unit
Following extreme temperature fluctuations, condensation may occur; therefore please do not switch on the
system until it has reached normal room temperature
(see chapter “Technical Description”).
No patient may be positioned in the unit during poweron.
In case of an error that requires switching off and subsequent switching on of the unit, the patient must be
removed from the unit before switching it on again at the
latest!
Emergency Stop If parts of the unit contact the patient during the rotational
movement , let go of the exposure release button (XRay) immediately and stop the unit by actuating the unit
main switch or an Emergency Stop switch!
Disturbance of electronic devices worn on the
patient’s body.
To prevent the malfunctioning of electronic devices and
data storage devices, e.g. radio-controlled watches,
telephone cards, etc., these objects must be removed
prior to X-raying.
Radiation protection The valid radiation protection regulations must be
observed.
The operator should move as far away from the X-ray
tube assembly as allowed by the coiled cable of the
exposure release button.
The statutory radiation protection equipment must be
used.
With the exception of the patient, no other persons
without radiation protection are allowed to stay in the
room. In exceptional cases, a third person may provide
assistance, but not the practice staff. During the whole
exposure, visual contact with the patient and the unit
must be maintained.

CAUTION
When switching on the unit, there must not be a patient
positioned in the unit.
If a fault occurs which requires switching the unit off and
then back on again, the patient must be taken out of the
unit at the latest before switching it on again!
Primary Diaphragm
Depending on the exposure program selected, diaphragm 1 or 2 is required. Diaphragm 2 is preferred for

6.2 Positioning the Patient
Preparations
• Have the patient remove all metallic objects such
as glasses and jewelry, from the head and neck regions. Have him take out removable dentures.
• Physical constitution, clothing, bandages etc. must
not interfere with the functioning of the unit!
Perform a test run with the T button (see page 26).
• Swing out the cassette holder (7) fully.
• Insert chin rest, bite block/contact segment or head
positioner, see ”Exposure Programs” chapter”.
Exposure with Chin Rest and Bite Block

• With programs P1, P2, P10, P11, P12, P14 and P15,
move forehead support to the 00.0 position by actuating the ← key.
For the forehead support setting for the other programs
refer to the ”Exposure Programs” chapter”.
• Have the patient stand in front of the mirror.
•Using the ↑ and ↓ buttons, adjust unit height so that
the chin of the patient and the chin rest match up.
Motoric movement is accompanied by an acoustic signal.
i
NOTE
The height adjustment motor starts up slowly and then
picks up speed.
• Have the patient place his chin on the chin rest and
grip the handles.
• Swing in the bite block.
• Have the patient bite the bite block at the indentation
(the upper anterior teeth should be directly in the indentation, and the lower anterior teeth should be
moved forward up to the stop).

12 Inspection and Maintenance Sirona Dental Systems GmbH
12 Inspection and Maintenance
As the operator, you should ensure the safety and reliability of your system by performing maintenance on it at regular intervals (at least once annually) or having this work performed by your dental dealership.
12.1 Annual inspection performed by the operator or other authorized personnel
As the operator, you should ensure the safety and reliability of your system by performing maintenance on it at regular intervals (at least once annually) or having this work performed by your dental dealership.
12.2 Maintenance performed by the service technician
In addition to the scheduled annual inspection by the user or persons contracted to perform this, a maintenance inspection
must be performed after 4, 7 10 and then every two yearsn.
12.3 Checking image quality
At regular intervals, however at least once a year, the user must evaluate the image quality.
For X-rays requiring developing of films, the increase in the kV/mA value pairs and the change in the density serve as the
evaluation criterion (for cephalometry, the increase in switching times as well).
If these evaluation criteria are fulfilled independently of the patient anatomy and of possible sources of error, such as developing of film or patient positioning, contact a service technician immediately in order to eliminate possible unit faults.
In addition it is necessary to observe country-specific requirements.
Furthermore, we would like to call your attention to the brochures of film manufacturers and also to our Quality Image Service.
For this, please contact your dental dealer or the manufacturer directly.
