postage to Aribex today. Completing the card fulfills a condition of warranty
coverage (see the inside back cover of this manual) and enables you to
receive valuable product news and updates.
1.3 Charging the Handsets
NOTE: The handsets (batteries) are partially charged at the factory and
normally need not be charged prior to initial use of the NOMAD Pro 2.
However, if the system has been in long-term storage prior to initial use,
handsets must first be fully charged before attempting to take X-rays.
It is recommended to fully recharge handsets every three months while in
long-term storage to ensure that no low battery becomes damaged.
 Use only the supplied AC/DC power supply (CP-0062). Unwrap the
power cord of the power supply and connect it to the charging cradle, then
to an AC electrical outlet (110/120V or 220/240V, dictated by the country/
region). The single green circle on the charging indicator will illuminate
green if there is adequate power to the charging cradle. If the green circle
does not illuminate, the charging cradle is not receiving adequate power
and may need to be sent to an Aribex authorized service center for repairs.
Position the charging cradle away from the normal patient environment. A
plug adapter may be needed to accommodate the local AC configuration.
 Invert one of the handsets and carefully slide it onto the charging cradle
(do not force the handset onto the charging cradle or damage may result).
Expect charge time to be less than three hours. The handset, charging
cradle, and AC power supply may become warm to the touch while
charging.
 When the handset is first slid onto the charging cradle, the first bar will
illuminate green for approximately two seconds to indicate that the cradle
and handset are communicating. If the first bar first illuminates green, but
then all of the bars illuminate red, the charging cradle and/or handset will
need to be sent to an Aribex authorized service center for repairs. Authorized
service will also be required if no illumination occurs upon sliding the handset
onto the charging cradle.
 After illuminating green, the first bar will begin flashing to indicate that
charging has begun. When the first bar turns solid green, the handset is 1/3
charged, and the second bar will begin flashing green. When the second bar
turns solid green, the handset is 2/3 charged, and the third bar will begin
flashing green. Once the third bar turns solid green, the handset is fully
charged. The handset may be left on the charging cradle after reaching a
full charge without damaging the batteries.

NOMAD Pro 2
2.0 Safety Precautions
2.1 Radiation Safety
This X-ray unit may be dangerous to patient and operator unless safe
exposure factors, operating instructions, and maintenance schedules are
observed.
• Operators must follow all applicable
regulatory guidelines and in-house
radiation protection programs in regard
to patients and operators who are
pregnant or expect to become pregnant.
• Operators must be fully acquainted
with industry safety recommendations,
established maximum permissible doses,
and local jurisdiction requirements for use.
• Optimal operator radiation back-
scatter protection exists when the following
measures are taken:
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 tilts his or her head when
needed to accommodate exposures (see
Section 4.8), and
d) the operator remains within the
significant zone of occupancy immediately
behind the device shield.
• Do not enable the 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.
• When selecting and using Position Indicating Devices (PIDs), 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.

9
OperatOr Manual
• 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 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 a lead apron
and thyroid collar, according to requirements of local jurisdictions.
• Do not operate if the backscatter shield or collimator cone is broken!
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.

2.2 Usage and Duty Cycle
As a safety feature, the NOMAD Pro 2 will not emit X-rays with insufficient
voltage (low battery).
The NOMAD Pro 2 is also designed to avoid damage from overheating. The
minimum duty cycle rating for maximum exposure (the relationship between
duration and frequency of exposures taken during a rolling 60 second period)
is 1:60. This duty cycle is programmed into your NOMAD Pro 2. The following
table shows examples of optimal use:
Exposure Duration 0.09 sec 0.20 sec 0.40 sec 1.00 sec
Hypothetical Time
Between Exposures 6 seconds 12 seconds 24 seconds 60 seconds
Exposures Per Minute >10 >8 >2 1
Do not operate the NOMAD Pro 2, the handset, charging cradle, or
AC power supply if equipment was subjected to moisture (wetting,
immersing, or soaking). Return to Aribex for service.
• Do not open the housings. Doing so will void the warranty. There
are no user serviceable parts inside the NOMAD Pro 2, handset,
charging cradle, or AC power supply.
• The NOMAD Pro 2 should not be used in environments where flammable
cleaning agents are present.
• Locate the charging cradle away from the normal patient environment.
2.3 Cleaning
 Routinely use a non-acetone based disinfectant wipe (according to
chemical manufacturer’s recommendations) to disinfect the exterior surfaces
of the NOMAD Pro 2 and the handset in between use on each patient.
 Leave the handset connected to the NOMAD Pro 2 and wipe down all
surfaces of the device.
 Unplug the charging cradle before cleaning.
NOTE: The NOMAD Pro 2, the handsets, the charging cradle, and the AC
power supply are not designed to be subjected to any kind of sterilization
procedure.
Do not spray disinfectant or cleaners directly on the NOMAD Pro 2,

NOMAD Pro 2
2.4 Security, Storage, and Transportation
• Do not store the NOMAD Pro 2, handsets, charging cradle, or AC power supply
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.
• Aribex recommends that the NOMAD Pro 2 (like all electronic equipment)
be allowed to acclimate before use when switching between temperature
extremes (i.e., cold storage area to a warm use area or hot storage area
to a cool use area).
• When finished for the day with the NOMAD Pro 2, detach the handset.
• The X-RAY LOCK and UNLOCK (Section 4.3) serves as the device security
key to prevent unauthorized use. In addition, it is recommended that the
device be locked away when not in use. For a further level of security,
securely store handsets in a separate location.
• Take steps to ensure the NOMAD Pro 2 will not be knocked to the
ground when not in use. Lay it on its top, side or in the accessory table-
top stand (AC-0005). Power will automatically shut off after a period of
inactivity (approximately three minutes).
• Do not store or carry handsets so that metal objects can contact exposed
battery contact springs.
• Some battery charge may be lost during extended inactivity (leading to
fewer exposures between handset charging cyles).
• The NOMAD Pro 2 should not be operated if it has been dropped
or if performance degrades; it should be returned to Aribex for an
evaluation.
• When finished for the day with the NOMAD Pro 2, detach the handset.
• For long-term storage, it is recommended to fully recharge the handsets
every three months.

OperatOr Manual
3.0 Setup and Power Check
3.1 The Backscatter Shield
In addition to the radiation shielded cone, the backscatter shield provides
additional protection to the operator and features an adjustable position to
permit exposures made at various angles.
 Ideally, the shield should remain fully extended to the outer edge of the
cone, as close to the patient as possible during each image taken (see 2.1,
Radiation Safety).
 You may find that the backscatter shield needs to be adjusted to
accommodate position indicating devices or angled exposures. If adjust-
ments are needed, gently glide the shield up or down along the cone using
equal pressure to maintain a perpendicular alignment and to avoid binding.
 To keep the shield securely on the cone, a cap is permanently attached
at the outer cone end. Do not attempt to remove this cap or to remove the
backscatter shield. Attempting to do so will result in damage to your device
and void the warranty.
3.2 Attaching a Charged Handset
 With the NOMAD Pro 2 placed bottom up on a secure surface, properly
orient and carefully slide the charged handsets onto the base of the NOMAD
Pro 2 (a properly oriented handset should click into place with firm pressure).
 The clicking sound ensures the locking mechanism has secured the
NOMAD Pro 2 to the handset. To verify this lock, apply slight pressure in the
release direction.
There are electric currents present at the handset terminals. Protect the
handset from damage; do not probe with fingers or conductive objects.

14

3.3 Checking for Power
 After locking a handset in place press the Power ( ) button.
 The operation control display panel will activate with a “battery power
level” icon in the upper right corner. Five bars is an indication of a fully
charged handset.
 If the battery charge is too low, the NOMAD Pro 2 will not emit an X-ray
and the RECHARGE HANDSET alarm will display. (The RECHARGE
HANDSET alarm may also display if the handset is not fully engaged.)
 When a battery is depleted to the single bar level ( ), it is recommended
the handset be recharged.
 Replace a low charge handset with the secondary handset (which
should be charged in advance).
3.4 Optional Checks
The NOMAD Pro 2 is factory calibrated and tested prior to release (see your
Certificate of Conformance). Each time the device power is turned on, it
automatically runs a self-diagnostic to ensure proper function. However, the
optional checks listed below may be performed periodically as desired.
Some locations may require initial and periodic checks as a condition of use.
The NOMAD Pro 2 has an X-ray disable feature that allows the X-rays to
be disabled for training purposes. Test firing this X-ray unit may otherwise

OperatOr Manual
4.8 Exposure Techniques
As an intraoral dental X-ray system, the
NOMAD Pro 2 can be easily positioned.
This high degree of flexibility easily
makes possible exposures while the
patient is reclined, lying completely on
their back, or sitting upright. Ensure the
patient is protected by using a radiation
shielding drape.
 When taking images, operators
may hold the NOMAD Pro 2 by having
both hands on the handset grip, or, for
increased stability and patient safety, by
placing one on the grip and the other on
the underside of the housing (but not on
the collimator cone).
 Position the NOMAD Pro 2 relative
to the imaging system to minimize
cone-cutting. (If your practice uses film
holding kits or aiming devices, check
compatibility in advance.)
 Exposure times increase proportionally
when the imaging angles vary away
from 90° (or perpendicular) to the film
or sensor. To maintain low patient X-ray
doses and to keep the operator within
the protection zone, have the head of
the patient slightly tilted, and/or raise or
lower the chin as needed. (See Section
2.1, Radiation Safety.)
 When the device must be angled and the operator cannot be completely
within the protection zone, ensure operator protection through the use of
proper safety measures, such as the use of a lead apron. (See Section 2.1,
Radiation Safety.)
 Avoid touching the patient with the cone or backscatter shield; disposable
plastic coverings can be used to prevent cross-contamination.
 Determine what NOMAD Pro 2 exposure time settings deliver optimal
results for the type of imaging (digital or film-based) that is used on a regular basis.
NOTE: Both digital imaging sensors and film speeds can vary somewhat in
their characteristics and could require different exposure settings to meet
density preference. (See Section 4.9, Settings Menu for more information.)
