2. SAFETY INFORMATION
WARNING:
Please read this chapter thoroughly.
Owandy Radiology designs and builds its devices complying with the
related safety requirements; furthermore it supplies all information
necessary for a correct use and the warnings related to danger associated
with X-rays generating units.
Owandy Radiology cannot to be held responsible for:
use of the I-Max Touch different than the intended use,
damages to the unit, to the operator, to the patient, caused both by
installation and maintenance procedures different than those
described in this manual and/or by wrong operations,
mechanical and/or electrical modifications performed during and
after the installation, different than those described in the service
manual.
Installation and any technical intervention must only be performed
by qualified technicians authorized by Owandy Radiology.
Only the authorised personnel can remove the covers and/or have
access to the components under tension.
SERVICE MANUAL
Safety information
I-Max Touch
2-2
2.1. Warnings
This device has not been designed for use in environments where
vapours, anaesthetic mixes flammable with air, or oxygen and nitrous
oxide can be detected.
Avoid pouring water, even accidentally, or other liquids into the device,
as this could cause short-circuits.
Before cleaning the device, be sure that the main power supply has been
disconnected from the equipment. Pushing the ON/OFF button on the
basement of the equipment, it mustn't switch on.
Wherever necessary, instruct the customer regarding the following:
to use the proper accessories, such as the leaded aprons, to protect
the patient from radiations
while performing the radiography, no one, apart from the operator
and the patient, must remain in the room
to replace the disposable bite protective sleeve and the
ear-centring devices after the use.
The I-Max Touch has been built to support a continuous operation at
intermittent load; therefore please follow the described use cycles to
enable the device cooling down.
Though this unit has been designed with a quite acceptable protection
level from electromagnetic interference, it is advisable to install it at a
certain distance from electric energy transformation chambers, from
Uninterruptible Power Supply (UPS) units, from receiving-transmitting
units for amateurs use. Mobile telephones are only admitted at a
distance of more than 1.5 m (4.9 ft) from any component of the device.
Other medical instruments and devices that could be used in the
installation area of the device, must comply with the Electromagnetic
Compatibility rules in force. Non-complying instruments, of which the
poor immunity from electromagnetic fields is well known, must be
installed at least 3 m (9.8 ft) from the I-Max Touch and supplied by a
different electrical line.
The I-Max Touch must be switched off while using devices such as
electrical lancets or the like.
Please clean and disinfect, when necessary, all parts that can be in
contact with the patient.
Never try to rotate the moving arm manually when the unit is
switched on, to avoid permanent damage to the unit.
The authorised technician must be sure that the unit is disconnected
from the main power supply before removing the covers.
SERVICE MANUAL
Safety information
I-Max Touch
2-3
The high frequency generator, located on the rotating arm, can hold
dangerous voltage for more than 2 minutes from the power off.
Though the X-ray quantity supplied by dental X-ray units is quite low
and distributed on a small surface, the operator must adopt the
precautions and/or fit protections for the patient and himself, during the
execution of a radiography. It is advisable to control the X-ray emission
from a protected area, by means of a remote control. In case it is
necessary to operate near the patient, please stay as far as the cable of
the remote control allows it, or at least 1.5 m (4.9 ft) both from the X-ray
source and from the patient, as shown in the picture below.

WARNING: PRECAUTIONS WHILE USING LASER CENTRING
DEVICES
Also if the laser devices, according to EN60825-1, are in Class I:
It is necessary to have an adequate illumination in the room.
Do not look into the output windows of laser centring units.
Do not stare at the reflections of laser pointers.
Instruct the patient to keep his/her eyes closed as long as the laser
pointers are active.
Before starting an examination, the patient must remove earrings,
glasses, necklaces and whatever else could reflect the laser beam or
be impressed on the radiographic image.
Do not clean the openings of the laser centring devices with tools that
could modify the optics. Necessary cleaning must be performed only
by authorised technicians. Operations different than those indicated
could cause the ejection of dangerous non-ionising radiations.
WARNING: PRECAUTIONS DURING INSTALLATION AND SERVICE
INTERVENTIONS
Please take the highest care while mounting the column to the wall
and strictly follow the instructions listed in this manual.
Before removing the covers of the column, or before removing the
covers of the Generator board (A10), disconnect the power supply to
the device, both switching the main switch and the magneto-thermal
differential off, and wait at least 2 minutes.
When the device is supplied without the above mentioned coverings,
pay the highest attention since high voltage is generated in the
supply unit, and the voltage is at about 400 Vdc on the Generator
board. This is indicated by the green LED H1. Should the LED be off
and before any other intervention, disconnect the device from the net,
wait at least 2 minutes, then check the fuses F1 (10AF) or F2 (5AF)
on the Generator board (see circuit diagram).
Each intervention must be performed after having disconnected the
device from the supply net and after LED H1 is OFF. It is anyway
advisable to wait at least 2 minutes from the LED's switching off.
The system construction does not allow the repair of
faulty/damaged parts that must be replaced using original spare
parts supplied by Owandy Radiology. Only trained personnel are
authorized to make service interventions on the unit, following
the instructions contained in this manual.
WARNING:
The USB port on the keyboard MUST NOT be used with an external Hard
Disk with own mains connection. It has to be used only with USB Pen
Drives.

3.2. Function, Models and Version
The I-Max Touch, produced by Owandy Radiology, is a complete
panoramic system, which enables to perform all radiographies commonly
necessary in dental field (except for endoral X-rays).
In some versions, certain examination modes are not available but the
device (thanks to its computerised control system) can be expanded and
updated with new releases, directly at the Dentist premises.
The basic version performs Panoramic, Emi-panoramic, Reduced dose
Panoramic, Frontal dentition, Improved orthogonality Panoramic, Sinus,
TMJ and Implant examinations.
Optional functions enable the system to perform the following additional
examinations:
CEPH
Allows you to carry out the following examinations:
CEPH exam in different formats
CARPUS exam.
3.2.1. Basic version
The basic version enables to perform the following examinations:
Panoramic Adult or Child, with 3 Sizes and 3 Types of Biting for a
total of 18 combinations in Automatic selection; in manual selection
it is possible to select high voltage between 60kV and 86kV, in 2kV
steps and anodic current from 6 mA to 10 mA in 1 mA steps.
Sinus enables to perform images of the paranasal sinuses with front
projection (postero/anterior).
TMJ mouth closed/open in lateral projection.
Implant to perform images of cross-sections of the dental arch, for
Implant medical treatment.
The right or left Emi-panoramic is used when the patient is known to
have a problem only on one side of the arch, in order to reduce the
radiation.
The reduced dose Panoramic reduces the dose radiated on the
dentition by excluding the TMJ's ascending rami from the exams.
The frontal dentition enables to perform examinations of the front
part (roughly from canine to canine).
The Panoramic with improved orthogonality reduces the overlap of
the teeth, thereby improving the diagnosis of interproximal decay.
