Operating Instructions GALILEOS 1.2 ESD protective measures
1.2 ESD protective measures
ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels
must not be touched or interconnected without ESD
protective measures.
ESD protective measures include:
• Procedures for preventing electrostatic charge
build-up (e.g. air conditioning, air moistening, conductive floor coverings and non-synthetic clothing)
• Discharging the electrostatic charges of your own
body on the frame of the unit, the protective ground
wire or large metallic objects
• Connecting yourself to ground using a wrist band.
We therefore recommend that all persons working with
this system be instructed on the significance of this
warning label. Furthermore, they also should receive
training in the physics of electrostatic discharges which
can occur in the practice and the destruction of electronic components which may result if such components
are touched by electrostatically charged
The content of this training is explained in Chapter 1.3.

1.3 About the physics of electrostatic charges Operating Instructions GALILEOS
1.3 About the physics of electrostatic charges
ESD stands for ElectroStatic Discharge. Electrostatic
discharge must be preceded by electrostatic charging.
Static electric charges generally build up whenever two
bodies are rubbed against each other, e.g. when walking
(shoe soles against the floor) or driving a vehicle (tires
against the street pavement). The amount of charge
depends on several factors:
Thus the charge is higher in an environment with low air
humidity than in one with high air humidity; it is also
higher with synthetic materials than with natural materials (clothing, floor coverings).
The following rule of thumb can be applied to assess the
transient voltages resulting from an electrostatic discharge.
An electrostatic discharge is:
• perceptible at 3,000 V or higher
• audible at 5,000 V or higher (cracking, crackling)
• visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges
have a magnitude of 10 amperes. They are not hazardous for humans because they last for only several nanoseconds.
Voltage differentials exceeding 30,000 volts per centimeter may lead to a charge transfer (electrostatic discharge, lightning, arc-over).
Integrated circuits (logical circuits and microprocessors)
are used in order to implement a wide variety of functions in dental/X-ray/CEREC systems. The circuits must
be miniaturized to a very high degree in order to include
as many functions as possible on these chips. This leads
to structure thicknesses as low as a few ten thousandths
of a millimeter.
It is obvious that integrated circuits which are connected
to plugs leading outside of the unit via cables are sensitive to electrostatic discharge. Even voltages which are
imperceptible to the user can cause breakdown of the
structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to individual integrated circuits may cause malfunction or failure
of the system.
To prevent this from happening, the ESD warning label
next to the plug warns of this hazard.

The resolution in the volume (voxel size) equals
0.3 x 0.3 x 0.3 mm
Scan time: 14 seconds
Effective radiation time: 2...6 seconds
Reconstruction time: approx. 2.5 minutes
Data volume: up to 500 MB
comprising:
Patient volume: approx.180 MB
Panoramic slice: approx. 4MB
Lateral cephalometric image: approx. 5 MB
Radiological views: approx. 5 MB

5.2 VO1 HC: Volume 1 (High contrast option (HC))
The VO1 HC (high contrast) program is selected on the
touchscreen, using the icon for the high contrast option
(see also section "High contrast option" on page 22).
Compared to the standard settings, the high contrast
setting VO1 HC is offers an improved display of hard
structures such as bones and teeth.
• The settings may result in an inferior display of the
soft tissue, especially in terms of the soft tissue silhouette.
The high contrast option is particularly suitable for the
evaluation of bone and tooth structures, e.g. after bone
augmentations, when the correct display of the soft tissue silhouette is negligible.
Additionally, the feature is particularly useful for the
DICOM export function to other implant planning programs (such as Nobel Guide or Simplant).
bеЦдблЬ
If the VO1 HC program is used for a DICOM export to a
third-party implant planning software, always choose the
setting value 42 mAs for optimal results.

standing patient. In special cases, you may also position
a seated patient (using e.g. a dentist stool). You then
must make sure that no parts of the dentist stool block
the beam path or impair unit movements.
Preparations
• Ask the patient to take off all metallic objects such
as glasses and jewelry in the head and neck area as
well as all removable dental prostheses.
• For patients with metallic implants, bridges and fillings, image quality can be affected.
• The movements of the unit must not be obstructed
by physical constitution nor clothing, dressings,
wheelchairs or hospital beds! Perform a test cycle
with the T key (see also chapter 1.1 "General safety

• Align the occlusal plane (S) of the patient's head parallel to the marking line (R) via fine adjustment of the
"up" and "down" keys.
The height of the X-ray unit must be set so that the occlusal plane is perfectly horizontal following alignment.
• The correct position for the indication can be set by
laterally fixing the position with the volume control
and using the vertical and horizontal adjustment options.
The inner side (T) of the volume control should be regarded as the volume boundary.
Example 1: The patient's nose and the point of his chin
are within the volume, e.g. for optimal display of the silhouette of a Ceph exposure.
Example 2: The horizontal adjustability makes it possible
to push the rear of the skull region (e.g. the temporomandibular joints) further into the volume. The tip of the
patient's nose and the point of his chin are pushed out of
the 3D volume in return.
• Finally, immobilize the patient's head by pushing the
two pins (B) toward his forehead until the forehead
rest (A) snugly fits against his head. Select the most
suitable forehead pad, i.e. M or N.
42 D 3437.201.01.09.02
The forehead rest can be returned to its zero position by
pressing the pushbutton (D).

6.3.3 Positioning the patient to the spherical bite block
Using the spherical bite block to create an
implant drilling template
Select the corresponding spherical bite block holder for
the scan with the spherical bite block. For exposures of
the lower jaw, insert spherical bite block holder (5). For
exposures of the upper jaw, insert spherical bite block
holder (6).
Spherical bite block plate (7) contains 6 radiopaque
markers (spheres) which are used for orientation in the
X-ray volume. Further applications can be set up on this
spherical bite block plate.
Aligning the patient to the spherical bite block
bеЦдблЬ
• Insert spherical bite block plate (7) with patient registration at the patient.
• Close swivel arm.
• Adapt unit height until sphere and incisors are at the
same height. The spherical bite block plate should
be aligned horizontally.
• Carefully lead the patient to the sphere of the spherical bite block holder with his mouth open.
• Have the patient gently bite onto the spherical bite
block holder.
The spherical bite block plate may touch the spherical
bite block holder only via the sphere. If it has contact at
the front, the patient's position or the unit height must be
corrected.

6.3.4 Display of the mid-sagittal plane
• Switch on the light localizer with key (12) on the
Easypad. It is used for correct patient positioning.
• Align the patient so that the light beam strikes the
center of the bite block and of the patient's face (midsagittal symmetry).
As long as the light localizer is switched on, a red light localizer symbol is displayed on the touchscreen (see
page 17).
Make sure that the light beam does not hit the patient’s
eyes (laser light). The light localizer switches off automatically after approx. 100 seconds.
• Fix the patient's position by tightening the forehead
support (2) against the patient's forehead with the
rotary knob (11).
In some cases, it is also advisable to immobilize the patient's head with a head fastening strap as well (see
chapter 4.1 "Bite blocks, supports and fasteners").
Concluding the preparations
• If the light localizer is still on, switch it off with key
(12) on the Easypad. The light localizer symbol on
the touchscreen disappears.

Be sure to observe the radiation protection regulations applicable in your country (see also chapter 1
"Warning and safety information")
• Check the program and exposure parameters carefully (see chapter 6.2 "Selecting exposure parameters").
No further help messages may be displayed in the comment line of the touchscreen. The message "Ready for
exposure” must appear.
If e.g. the door of the X-ray room is not properly shut, the
message "Close the door” appears in the touchscreen
comment line; at the same time, the coded message
H321 is displayed on the remote control.
bеЦдблЬ
Advise the patient not to move his/her head in any way
during the exposure and check to make sure that this
does not happen!
In order to attain optimal image quality, the patient should
avoid any unnecessary breathing or swallowing during
the exposure.
• To release an exposure, press the exposure release
button (5) directly on the X-ray unit or on the remote
control.
The rotary movement of the selected exposure program
is performed automatically.
While radiation is active, the optical radiation indicator
(15) on the Easypad or on the remote control is
illuminated.
In addition, an acoustic signal sounds throughout the
entire radiation time.
Take care not to let go of the exposure release button
prematurely. Wait until the unit has completed the exposure cycle.
If the exposure is canceled prematurely, you will obtain a
much poorer image quality, since not enough image data
will be available for reconstruction of the volume.

6.5 Remote control
If the X-ray unit is located in an X-ray room which has a
door and enables visual contact with the patient, you can
use remote control to release the exposure.
For that purpose, the exposure release button (5) can
be detached from the unit and attached to the remote
control.
The exposure release button (A) can be used if a
longer cable is not required to maintain visual contact
with the patient.
The remote control has an “R” key (18) for acknowledging the exposure and resetting the unit to its starting
position, an optical radiation indicator (15) and a "Unit
ON" LED display (16).
After you switch on the system, the LED (16) lights up.
The radiation indicator (15) lights up for a longer period
of time for a function test.
The three display fields on the display panel (B) light up.
A progress bar appears after approx. 10 seconds. After
the system starts, the display switches to program VO1
with the corresponding values.
As long as plain-text help messages are displayed on
the Easypad touchscreen, they also appear in coded
form on the "Prog." display field of the remote control,
alternating with the program name.
Once all help messages have been processed, the pro-
gram name “Prog.”, the “kV” and the “mAs” values are
constantly displayed on the display panel (B).
The exposure can be released.
If a row of dots ........ appears in the Prog. field, this
means that the system is currently in a preparatory
phase (e.g. system movements, parameter changes,
program loading times etc.). Just wait until the dots automatically disappear and the system signals that it is
ready again.

7.3 Error message E1 10 07
Explanation
This section describes the possible causes and the correction of this error.
Case 1
In case of longer periods of disuse (> 200 hours), the
X-ray detector (sensor) will require a preparation time of
up to ten minutes.
The system will display the message "Sensor preparation in progress."
During that time, the device is not ready for operation.
If the system is set to readiness for exposure during that
time, error message E1 10 07 will display.
Solution
Acknowledge the error message with the (R) key and
wait until the message "Sensor preparation in progress"
is deactivated.
Decreasing the waiting time
Switching the unit on and off will not decrease the waiting
time!
Case 2
If the error message E1 10 07 is displayed immediately
after turning on the device without the user having established exposure readiness, please inform the responsible service engineer.
