5 Function
Provecta HD is an extraoral x-ray unit and is factory set at the correct x-ray dosage for each dental
area required using Air Techniques image plates and sensors. It consists of a control unit, an arm ex-
tension system and an x-ray tube assembly.
The handle on the x-ray head unit allows the x-ray tube to be positioned precisely.

5.2 Exposure switch
The exposure switch can be used as alternative to using the control panel to activate irradiation.
5.3 Radiation field collimation
The radiation field collimator reduces the useful x-ray field to the required dimensions. This reduces
the x-ray exposure to the patient. Observe any national regulations.
5.4 Wall mounting plate
A wall mounting plate must be used for Provecta HD installations. There are two mounting plates
available; one for single stud installations and a 16 on center plate used when there are dual studs.
Refer to the Installation manual for instructions to install the Provecta HD unit.

Setup
Only fully-qualified or from Air Tech-
niques trained personnel may set-up,
install or operate this appliance.
6 Prerequisites
The room chosen for set up should fulfil the
following requirements:
Closed, dry room.
– Should not be a room made for another pur-
pose (e.g. boiler room or wet cell).
– No large fields of interference (e.g. strong
magnetic fields) present, that can interfere
with the function of the unit.
– Take environmental conditions into consider-
ation section 4, Technical data".
7 Tube and Power Setup
7.1 Mount tube (optional)
• Place the 12 in. (30cm) tube extension in po-
sition and check whether the grooves match
correctly.

7.2 Mount radiation field
collimation
• Slide the radiation field collimator piece onto
the tube and adjust according to the image
plate or the sensor.

7.3 Safety for electrical connection
• The appliance may only be connected to a cor-
rectly installed electrical socket outlet.
• Do not lay multi-socket units on the floor. Speci-
fications of IEC60601-1-1 apply.
• Other systems should not be plugged into the
same multi-socket unit.
• All cables, etc. must be laid so that no mechani-
cal tension is exerted on them.
• Before start-up or first use, check the mains
voltage against the voltage indicated on the
model identification plate (see also "4. Technical
Data").
7.4 Connecting the appliance to the
power supply
Requirements:
9A correctly installed socket-outlet in the vicinity
of the unit must be available (maximum length
of mains cable 6 ft. (1.8m)
9The socket-outlet must be easily accessible
9Voltage is identical to that given on the model
identification plate
9Insert plug into electrical socket

Setup
8 Operation
The necessary tests (e.g. acceptance test) are regulated by the locally applicable national law.
• Find out which tests are to be made.
• Carry out tests in accordance with national law.
8.1 Operational check
When carrying out the commissioning tests where the image
plate and sensor are used as receiver, the 2-D X-ray test phan-
tom is required and possibly the appropriate 2-D X-ray test
phantom holder.
• Before initial unit operation the commissioning test of the x-ray system must be carried out accord-
ing to national regulations.
The tests of constancy, which must be carried out at regular intervals by the surgery personnel, are
based on the results of the commissioning test.
8.2 Electrical safety check
• Carry out an electrical safety check according to all national regulations (e.g. patient conductivity,
conductivity of housing).
• Document the results.
8.3 Switch unit on
The display will show the standard values for x-ray exposures or the setting values used for the last
exposure carried out.
– Operational display lamps,
– LED for menu tooth symbol,
– LED for menu Adult/Child and
– LED for menu image plate/sensor all light up.
8.4 Service menu settings
• While pressing the button and additionally the button a little longer in order to switch to the
Service-menu.
• Under menu option 1. Cone Type move to appropriate value with or scroll through and then
use to confirm.
• Under menu option 2. Cone Type move to appropriate value with or scroll through and then
use to confirm.
• Under menu option 3. Default Value Reset, press to confirm reset.
• Under menu option 4. kV Option move to appropriate value with or scroll through, 50-70 kV
are permissible in countries with no x-ray limit regulations. Use to confirm.
• Under menu option 5. X-ray Count move to appropriate value with or scroll through. Use
to confirm.
Resetting the counter is password protected.
• Under menu option 6. Version the current Firmware Version can be called up. Use to confirm.
• Under menu option 7. Demo the Demo-Version can be started by pressing .
• After entering all required values press to exit the Service Menu.

Usage
Bisection angle technique
The patient should hold the image receptor in
the mouth in the correct position. The middle of
the radiation ray is set at right angles to an (esti-
mated) plane at half the angle between tooth
axis and image receptor.

1 Image receptor
2 Tooth axis
Upper jaw front tooth exposure
X-ray is projected 45° downwards
Lower jaw front tooth exposure
X-ray is projected 25° upwards
Upper jaw molar and premolar exposure
X-ray is projected 25° upwards
9.2 Positioning patient, X-ray
unit and image receptor
CAUTION
Injuries to the oral cavity
Sharp-edged receptors can cause inju-
ries to the oral cavity.
• Careful positioning of the image re-
ceptor into the patient's oral cavity.
• Allow the patient to sit down.
• Position the image receptor inside the oral
cavity
• Position the x-ray unit.
CAUTION
Image quality insufficient
If the x-ray unit is moved or if the patient
moves during exposure then the images
will not be usable.
• The patient should sit quite still during
x-ray exposure.
• The x-ray unit must not be moved in
any way during exposure.
The image receptor can be any of the following:
– Film
– Sensor
– Image plate
Ensure that the image receptor is
placed within the x-ray field.
Place the tube close to the skin.
Parallel techniques
Position the image receptor using a holder sys-
tem for parallel techniques.

CAUTION
Injuries through x-rays
X-rays can cause tissue damage.
• Observe all x-ray regulations.
• Keep a minimum safety distance of 5
feet (1.5m.)

NOTICE
Unit damage due to switching
frequency being too high
If sufficient cooling of the x-ray unit is
not ensured, this can lead to damage.
• Only activate the subsequent x-ray
image after the displayed cooling time
has elapsed.
• Check x-ray settings on control panel and
change if necessary
– Change the tooth region using menu tooth
symbol
– Change to adult or child using patient menu
• Check x-ray parameter and change if neces-
sary
• Depress exposure button
– The x-ray unit control lamp lights green -> unit
is warming up
– The control lamp lights orange and an acous-
tic signal is heard -> unit is exposing
Lower jaw molar and premolar exposure
X-ray is projected 5° upwards
Bite wing technique
During the bite wing exposure the patient needs
to bite on a bite wing holder.
X-ray is projected 5 to 8° upwards
