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 IEC 60601-1 for medical electrical equipment.

1 Warning and safety information Sirona Dental Systems GmbH
Operating InstructionsM1
Combination with other unitsAny person who assembles or modifies a medical elec-
trical system complying with the standard IEC 60601-1-1
(Safety requirements for electromedical systems) by
combining it with other equipment (e.g., by connecting it
with a PC) is responsible for ensuring that the requirements of this regulation are met to their full extent for the
safety of the patients, operators and environment.
In case of doubt, contact the manufacturer of the system
components.
+
Electromagnetic compatibility (EMC)The M1
+
complies with the requirements of
IEC 60601-1-2:2001.
Medical electrical devices are subject to special precautionary measures regarding EMC. They must be
installed and operated as specified in the document
"Preinstallation Instructions".
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.
For video systems:
Electromagnetic disturbances in the environment of the
+
M1
may result in reduced image quality. In such cases,
it is advisable to repeat the exposure before saving the
image.
In case of line voltage fades, öimage data stored in the
video camera may be lost. Deposit the camera and
repeat the exposure.
Image artifacts may possibly occur in the event of
radio-frequency interference caused by the transmitters
of e.g. radio services or radio amateurs.
Treatment of highly immunosuppressed patientsHighly immunosuppressed patients should not come in
contact with water from the treatment center. The use of
sterile solutions is recommended.
Quality of water / air supplyAir and water supply must meet the requirements speci-
fied in the Installation Instructions. Use only clean
water.
Water quality complianceTo ensure compliance with the medical and national
legal requirements for water from treatment centers,
Sirona recommends equipping the treatment center with
a disinfection system. As owner of the treatment center,
you are responsible for the water quality and may have
to take alternative measures to ensure its compliance if
you operate the treatment center without a disinfection
system.
Please contact your specialized dealer or your relevant
dental association for the respective national requirements and measures.
HF surgeryThis dental treatment center is available with a high-fre-
quency surgical device (optional).

No restrictions apply when using salt blasting devices in
connection with Sirona treatment centers. However, in
such cases, make sure that the system is subsequently
rinsed with an adequate amount of water.

Initial start-up
The disinfection system adds a disinfectant to the water
(1:100) to prevent the formation of microorganisms in
the water system.
Prior to initial start-up of your treatment center, sanita-tion must be performed.
If, on the basis of an agreement with you, sanitation was
skipped by the service engineer following installation of
your treatment center, please perform sanitation yourself as described in the separate instructions “Care and Cleaning by the Practice Team”.
Sanitation takes approx. 24 hours.

Adjustment to patient's height
The headrest can be adjusted to the patient's height by
pulling out or pushing in the headrest extension. This
adjustment is usually required at the beginning of treatment!
i
NOTE
Before positioning the patient on the headrest, make
sure that the head support has been optimally adjusted
to the patient's height. This simplifies all subsequent
work with the MultiMotion considerably, since readjustment to the patient's height can thus be omitted when
changing over from mandibular to maxillary treatment.
The MultiMotion enables you to adjust the patient's head
in a way that optimally supports viewing of areas of the
mouth which are difficult to access.
+
Adjustment of hyperextension
Mandibular position
The mandibular position can be set by pulling the operating handle (A). The anatomical movement of the
arched extension keeps the patient's head in the support.
Pull the headrest out of the guide by pulling
handle A.
i
NOTE
You can reduce the adjustment noise by pressing
release A.

Removing the MultiMotion
For certain treatments (e.g. of children) it may be expedient to remove the MultiMotion completely in order to
obtain better access to the patient. The patient's head
will then be supported on the contact surface of the
headrest extension F.
To remove the MultiMotion, proceed as follows:
1. Press release button C.
2. Pull the complete headrest out of the headrest ex-
tension.
3. Cover the opening of the headrest extension with
cover cap E.
4. If a children's head pad D is available, place it on
the headrest extension. The head pad is held magnetically.
i
NOTE
The children's head pad (D) is not included in the scope
of supply, however, is available from your dental dealer.
+
WARNING
The children's head pad (D) contains a strong magnet on its bottom side. This magnet could affect any
cardiac pacemaker located nearby.
Therefore, do not allow patients, users and technical
personnel with a cardiac pacemaker to be located
near this magnet.
Furthermore, direct contact of the head pad with
magnetic cards can lead to data loss.
i
NOTE
Deposit the removed MultiMotion in a safe place where it
cannot fall onto the floor.
Inserting the MultiMotion
To insert the MultiMotion, proceed as follows:
Check the guide of the removed headrest for con-
tamination. Remove any contamination.
Remove the cover cap E.
Reinsert the MultiMotion in the guide from above until it
audibly locks in place.
Pull on the headrest again to make sure that it is
locked securely in place.
