contained on the CD shipped with this device.
BASIC OPERATION
nAttach a fully charged handset.
oTurn the power on by pressing the Power ( )
button.
pSelect Patient Size
(Larger or Smaller
).
qSelect Image
Receptor type (Film
, Phosphor Plate ,
or Sensor ).
rSelect the Tooth
Group (Molars ,
Pre-Molars , or
Incisors/Canines ). For more on adjusting the
time settings see the
Operator Manual contained on
the CD.
sPosition the NOMAD Pro relative to the receptor.
tPull and release the trigger once to put the NOMAD
Pro into the READY state.
uPull and hold the trigger (a second time) until the
X-RAY COMPLETE is displayed and the audible
tone indicates the exposure is done.
vTurn off the power by pressing the Power ( )
button.
Do not operate NOMAD Pro or the handset, charger cradle,
or AC power supply if equipment was subjected to moisture.
Do not spray disinfectant or cleaners directly on the NOMAD
Pro, handset, charger cradle or AC power supply. Damage to
your device or a shock hazard may result. Consult the
Operator Manual on the CD for proper cleaning instructions.
Do not open the housings. Doing so will void the warranty.
There are no user-serviceable parts inside the NOMAD Pro,
handset, charger cradle or AC power supply.
Locate the charging system away from the normal patient
environment.
NOMAD Pro should not be operated if it has been dropped or
performance degrades; it should be returned to Aribex for a
safety check.
HANDSET (BATTERY)
CARE
The following are important handset care notes:
¾Each handset can go through the full
discharge/charge cycle approximately 300 times.
Routinely change out a discharged handset with
fully charged one as needed.
¾Remove the handset from the charging cradle once
it is fully charged.
¾Battery charge will diminish during extended
inactivity – fully recharge handsets every 3
months during inactivity. Never place a low
charge battery into long-term storage.
¾Do not store handsets in extreme conditions: below
–20°C (–4°F) or above +60°C (+140°F), or beyond
95% relative humidity (non-condensing). The
optimal storage location is cool, dry, and away from
direct sunlight.
¾Do not store or carry handsets so that conductive
objects can contact exposed battery contact
springs.
¾When the charging cradle senses a bad handset
battery, the indicator lights will illuminate red rather
than green. In this case, the batteries are
inoperable and must be serviced.
¾Handset communications and mechanical integrity
are checked by pulling the handset trigger when it
is on the charging cradle – good communication
exists when the indicator lights illuminate orange.
Do not attempt to charge a handset with damaged batteries.
Risk of fire or explosion exists if batteries inside the handset
are replaced by unauthorized service personnel; do not use
batteries from other sources.
Properly dispose of spent or damaged handset; return to
Aribex or an authorized distributor for replacement and
recycling. Do not place in municipal waste stream.

THE NOMAD® PRO
DIFFERENCE
NOMAD Pro is safe to be used as a handheld X-ray
source. There is no need to leave the room during an
exposure.
Aside from the direct beam, X-ray devices have two
potential operator radiation sources: 1) leakage radiation
and 2) backscatter radiation bouncing back off the
subject.
1) Leakage – Unique internal shielding of NOMAD Pro
encases the X-ray tube eliminating leakage
radiation. As demonstrated by the data below, this
makes it safe to use NOMAD as a handheld device
during exposures.
2) Backscatter – When properly oriented, the
transparent shield on NOMAD Pro collimator acts as
a barrier against backscatter radiation, making it
safe for the operator to stay in the room.
As a result of the internal and backscatter
shielding, operator X-ray exposure is far below
federal regulatory limits.
RADIATION SAFETY
Operators must follow all applicable regulatory guidelines and in-
house radiation protection program in regard to patients and
operators who are pregnant or expect to become pregnant.
Operators must be fully acquainted with industry safety
recommendations and established maximum permissible doses.
Do not enable NOMAD Pro 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 patient is in the
direct beam. If others are assisting, then they should wear
protective covering.
An exposure can be terminated for any reason by abruptly
releasing the depressed trigger.
Optimal operator radiation backscatter protection exists when:
a) The backscatter shield is positioned at the outer end of the
collimator cone.
b) The backscatter shield is close to the patient.
c) The patient is situated to accommodate exposures that allow
the NOMAD Pro to be positioned perpendicular to the operator.
d) The operator remains within the significant zone of occupancy
immediately behind the device shield.
As shown in graphic representations, maximum protection (green
area) from backscatter radiation (red area) exists when the NOMAD
Pro is positioned near the patient, is perpendicular to the operator
with the patient (oval) positioned/tilted as needed, and the
backscatter shield is fully extended toward the patient.
Proper postioning Held back Shield slid back Non-perpendicular
PROTECTION:MAXIMUM MINIMIZED
Operation outside the protection zone (or with a diminished
protective zone) requires proper precautions such as the use of
lead aprons.
