Operating Instructions ORTHOPHOS 3
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 3 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, condensa-
tion 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
power-on.
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
(X-Ray) 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.

This moves the patient's cervical vertebrae into a more
stretched out position.
The cervical vertebrae ”stretched out” ensures that the

The rotation movement runs automatically in accordance with the exposure program selected.
For P6 program only
The rotation unit returns back into the start position after
having completed the program part P6.1. Then have the
patient open his mouth wide and initiate the second program part P6.2.
During radiation
the X-ray radiation indicator lights up. The radiation
duration is additionally accompanied by an acoustic
signal.
• The exposure ends when the LED over the R key
flashes. Rotation and radiation automatically
switch off.
Open the temple supports and have the patient step out.

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
