• Do not enable the KaVo NOMAD PRO 2 until patient and operator are positioned and
ready for the exposure, preventing interruption and inadvertent exposure of anyone to
X-rays.
• Do not attempt an exposure if anyone other than the patient is in the direct beam. If
others are assisting, then they should wear protective covering as required by local
jurisdictions. An apron and thyroid collar are recommended for ancillary personnel
who are closer than 6 feet to the patient.
• When selecting and using sensors, preference should be given to models that allow
the backscatter shield to remain at the outer end of the collimator cone for maximum
operator protection.
• An exposure can be terminated for any reason by prematurely releasing the depressed
trigger (for more information, see
Section 4.0 Operation
).
• As shown in graphic representations, maximum protection (green area) from
backscatter radiation (red area) exists when the KaVo NOMAD PRO 2 is positioned
near the patient, is perpendicular to the operator (with the patient’s head tilted if
needed), and the backscatter shield is fully extended toward the patient and parallel
to the operator.

• Operation outside the protection zone (or with a diminished protection zone) requires
proper precautions such as the use of an apron and thyroid collar, according to
requirements of local jurisdictions.
• Do not operate if the backscatter shield or collimator cone is broken.
• For further information on the tests performed to ensure KaVo NOMAD PRO 2 safety
as a handheld device, please see
Section 2.2 Studies and Data on Leakage and
Scatter
.
In implementing a radiation protection program, consult all applicable regulations
governing radiation protection and the use of X-ray equipment, and ensure full
compliance with any such regulations.
