2 Introduction
● When taking an x-ray exposure of a patient with exceptional anatomy (typically very
tall or large) use the Test-mode (no x-rays) first to make sure that patient can be
positioned correctly to the unit and for checking that the unit doesn't hit the patient.
● Operator should maintain visible contact with the patient and technical factors. This
allows immediate termination of radiation by the release of the exposure button in the
event of a malfunction or disturbance.
● It is the responsibility of the doctor to decide whether x-ray exposure or any
additional exposures are justified and necessary.
● The minimum height of patient that can be x-rayed in standing position is 120cm
(3.9ft/47.2in). The maximum height of patient in standing position is 200cm
(6.5ft/78in) in all other programs, except in 130 x150 mm 3D program, where it is
193cm (6.3ft/76in). Taller patients must be seated during imaging. These heights only
apply to patients with normal anatomy.
● Unit can collide with the legs of a seated patient when driving the carriage
downwards. Pay attention on the unit movement.
● Always use the lowest suitable x-ray dose to obtain the desired level of image quality.
● Avoid taking x-ray exposures of pregnant women.
● When taking an x-ray exposure of a child always use the lowest possible x-ray dose,
the smallest possible image area and the lowest possible resolution that allows you to
perform the required diagnostic task.
● If the patient is using a pacemaker, consult the manufacturer of the pacemaker before
taking an exposure to confirm that the x-ray unit will not interfere with the operation
of the pacemaker.
● Decontaminate all the surfaces that the patient is in contact with after every patient
to prevent cross infection.
● Decontaminate all device accessories that contact the patient during a radiographic
examination.
● Check that the power supply cable is properly attached to the mains socket and
visually check the cable for damage. If the cable is damaged, it shall be replaced by
authorized service technician only.
● Do not open or remove any of the unit’s enclosures. No user serviceable parts inside.
● Do not touch the patient and any exposed electrical connector, such as sensor
connector or Ethernet port, simultaneously.
● The customer must ensure that the siting environment fulfills the requirements listed
in the Installation manual. Special attention must be paid to the strength of the floor
and wall materials, electrical mains and radiation protection. It is the responsibility of
the customer to ensure that the site is large enough for the patients.
● The unit contains toxic materials that need to be handled properly when disposing the
unit. Return the unit to the dealer in the end of its life cycle.
● Excessive dust should be cleaned from the unit for free airflow and cooling. Switch of
the unit before cleaning.
● Always follow the instructions for patient positioning and imaging procedures
instructed in the User Manual.
● In case of water damage/water dropping over the product, call for service technician
to ensure the product is fully operational according to specification.
2.10.2 Warnings for cross infection
Always use available disposable protective covers with the patient positioning
accessories:
● Bite fork cover
● Chin support cover
● Head support cover
● Nose support cover
● Ear rod cover
