Although the dose supplied by modern X-ray units is quite low, the
operator must adopt the precautions and/or suitable protection for the
patient and himself according to current regulations, during the
execution of radiography.
WARNING:
Protection against radiation is regulated according to law. The equipment
may only be used by specialised personnel.
a) The film (or the digital sensor) must be placed in the patient's mouth
either manually or using the specific supports, and must be held in
position by the patient if necessary.
b) During exposure to the rays, the operator must not be in contact
with the tube-head or the collimator cone.
c) During exposure, the operator must maintain a certain distance from
the source of the rays (at least 2 metres) in the opposite direction of
the emission.
d) During exposure, only the operator and the patient may be present
in the room.
e) Use the specific leaded aprons to reduce the undesired effect of
secondary radiations for the patient.

The Endograph DC intra-oral X-ray unit makes it possible to obtain
consistently high quality X-rays thanks to the reproducibility of the unit
parameters with very short exposure times and a very small focus spot.
The Endograph DC intra-oral X-ray unit is compatible for being
combined with digital image acquisition systems, thereby obtaining the
maximum benefits of today's digital intra-oral radiologic technology. If
you do not currently have a digital system, the use of high-speed film or
film in the EKTRASPEED (Kodak) category is recommended in order to
limit the dose absorbed by the patient. A button on the control keypad is
used to select the operating mode and it is possible to select films with
different speeds (sensitivity), the phosphor sensor, the digital sensor or a
customised user mode "Custom mode".
The Endograph DC X-ray unit has an LCD display with dimensions of
84mm x 45mm (240x128 pixel) which makes it easier for the operator to
perform all operations, guaranteeing the immediate and complete display
of the exposure parameters.
The Endograph DC system can use the optional 30 cm collimator cone
(to be ordered separately with code 6159400000). The "long cone
inserted" selection is signalled by the specific symbol on the display. In
this configuration, the exposure times that were pre-set in the anatomic
selection are automatically increased by a multiplicative factor of 2.
The Endograph DC system includes the following: generator, tube-head
complete with collimator, CPU (or logic) card that controls the system
functions, keypad, extension arm and scissors arm.
WARNING:
The Endograph DC system does not automatically detect the presence of
a cone or other item: the operator is responsible for checking the
congruity between the indication on the display and the actual situation
of use.

The remote controlled HF generator, together with the tube-head, uses
state-of-the-art microelectronic technology to obtain optimal quality
X-rays while reducing the patient dose of rays. Conventional systems
generally use the intrinsic capacity of the RX generator tube to conduct
the electric current in one direction only. This generates a "train" of RX
impulses. The Endograph DC unit instead uses constant-voltage
technology that generates continuous and stable emission of X-rays.
This reduces the emission of soft rays, guaranteeing the constancy of the
emission parameters, kVp and mA.
The microprocessor-based control ensures constant and repeatable
exposure times; by simply pressing a button it is possible to
automatically select the exposure times based on the size of the patient
and the selected tooth.

This consists of an arm with a double joint, which permits horizontal
and upward extension. The tube-head remains balanced in all positions.
NOTE:
The scissors arm was designed to work correctly with a maximum
opening angle of 160°; therefore, an opening angle of less than 160° is
required for its use.
A horizontal extension arm can also be added, which is available in
different sizes (30 / 60 / 80 cm) to satisfy all requirements.

The tube-head makes it possible to select one of three different high
voltage values: 60 / 65 / 70 kVp.
The radiogenic unit is equipped with a collimator with a focus skin
distance of 20 cm and a ray emission diameter of 6 cm at the cone exit.
The tube-head is connected to the arm by a guide, which permits 390°
horizontal rotation and 290° vertical rotation.

The timer consists of an LCD display (240x128 pixel), two LEDs
(yellow: X-rays in progress– green: ready for X-rays) and 5 buttons
that are used to select from among 3 different patient sizes, 3 types
of sensors (film, phosphor or digital) and 7 different pre-set
anatomical structures (incisor, canine, premolar, lower molar,
upper molar, front bite-wing and rear bite-wing).
There are 36 fixed times available for manual selection which vary
from a minimum of 0.01 seconds up to a maximum of 2 seconds.
The timing is managed in order to guarantee exact precision of the
exposure times.
NOTE:
The configuration can be set using the remote X-ray control outside the
examination room. This consists of a wall support onto which the X-ray
button is connected with an extendable cable.
NOTE:
The unit provides two separate contacts for the possible connection with
external signalling devices. One contact signals the status of the unit as
operative and ready to be used, the second emits the X-rays. The
connection methods and the requirements necessary for the signalling
devices are described in the "Service Manual".

The measuring method with non-invasive instruments, for example
kV
p
/t meter, is accepted, even if it generally provides less accuracy. In
fact, the measurement of the high voltage at the tube with non-invasive
instruments is closely correlated to the method selected by the
instrument manufacturer; in general, this method is more inaccurate
than the direct method and may also require two subsequent exposures.
In the same way, the method of measuring the anodic current with the
indirect method is affected by systematic errors, as they are often based
on the measurement of the current/time product, dividing the
measurement by the time measured with the said method.

The kVp value is defined as the stationary value of the high voltage
applied at the tube that is stabilised under load after the pre-heating
time.
Measure the value of the kVp with a non-invasive instrument (with
2% accuracy), setting the exposure time to 1 second.
• DEDDEDD

The exposure time must be measured using a non-invasive
instrument.
In compliance with standard IEC 60601-2-7, the exposure time is
measured as the interval of time between the moment in which the
high voltage has reached for the first time a value equal to 75% of
the peak value and the moment in which it goes down below this
value.

Endograph DC does not ask for special pre-installation works, still it is
necessary to grant an adequate grounding for EMC compatibility and
safety.
Section of grounding cable must be at least equal of greater than the
section of line cables. It is advisable to use a grounding cable with
section 2.5mm².
If cables are going to be positioned inside the wall, it is better that ducts
are already positioned, taking into account where the device will be
installed, taking care that cables exit in correspondence of the hole on
the lower side of the wall plate.
The Manufacturer can assist technically in the pre-installation phase,
but preparation works are a customer’s responsibility.

NOTE:
This chapter is valid for Wall version. The user does not need to assess
the consistency of the wall for Stand version.
The installer is responsible for assessing the consistency of the wall.
The extraction load on each screw is 446 N (46 kg) for the wall version
standard assembly (3 mounting screws), 634 N (65 kg) for the wall
version "single stud" assembly (5 mounting screws).
For each type of wall use the appropriate mounting method complying
with the following specifications which guarantee a safety factor 4:
• Wooden uprights: self-threading screws 8x70 A 4.8 (provided with
the installation kit)
• Full or concrete bricks: screw anchors (provided with the installation
kit) in cast iron M8 or chemical screws WURTH (not provided)
• Hollow bricks: chemical screws (not provided).

At start-up the timer automatically checks all the internal hardware and
particularly:
• Display lights ON
• LEDs light for 2 seconds
• CHECKSUM check of the storage program and display of the words
"CH0" if the check result is negative or in the event of non-initialized
memory
• Buzzer check (rings)
• Check of all buttons and X-ray buttons in particular, no button must
be pressed. If any buttons are pressed an error code message will
appear on the display
• Showing of software and hardware versions (HW: X.XX – SW: X.XX).
NOTE:
During the first start-up, the volatile memory may not be programmed
and therefore the "CH0" message will appear. In this case, press "F" key
to restore the factory default setting. The "CH0" message must not be

rotating one of the wrenches ¼ of a turn each time.
4. When you have finished the adjustment, tighten the
previously loosened dowel and reassemble the plastic covers.
– Adjusting the spring (picture B)
If adjustment of the friction is not enough, you can adjust the
spring to optimise the balance:
1 Put the arm in a horizontal position; remove the plastic co-
ordinator covers. This must be done carefully to avoid
breaking the covers themselves.
2 Insert a 6mm hexagon wrench (about 200mm long –
contained in the kit P/N 6661209900). This wrench must
rotate clockwise if the arm tends to go down compared to
the release position; anticlockwise if it tends to go up.

Like all electrical equipment, this unit requires not only correct use, but
also maintenance and checks at regular intervals. This precaution will
guarantee that the equipment works safely and efficiently.
Periodic maintenance consists in checks carried out directly by the
operator and/or by the Technical Service.
The operator can carry out the following checks himself:
• check there are no oil marks on the tubehead
• check the remote control cable is not broken or scratched
• check there are no external damages to the equipment which could
make it unsafe in terms of protection from radiation
• check the scissors arm balance
• check that the X-ray beam is centered
• check proper functioning of X-ray exposure LED and exposure
buzzer
• check the plates are intact and well attached.
The Service Engineer, during preventive maintenance, besides the
checks listed above, will verify also:
• correct adjustment of the rotation friction mechanism of the
extension arm and of the scissors arm
• correct balancing of scissors arm, making proper adjustment when
necessary.
