2. Introductions
This manual is made for using instrument safe and rightly. This manual not respect
changing the running mode and safety from external damage to instrument.
This high frequency inverter type of the photo/imaging system is operated by the built-in
operation program. It is comfortably designed to satisfy the operator's comfort as well as to
enhance the efficiency and the quality of X-ray. Operator can easily select or change the
necessary conditions for necessary photographs/images.
(1) This manual is made for operating instrument safe and rightly
(3) Read this manual carefully before using the instrument. Keep this manual closely
for referring later.
(4) EVA HF325/525 is a radioactivity medical instrument and using under the medical
management. So it needs the authorized person who has the know-how about the
X-ray.
(5) High voltage generating circuit provides stable X-ray out put with little radiation
through rectifying electric wave method.
(6) X-ray tube system is made in rotary bipolar method which uses two foci(small
focus 1.0mm/ large focus 2.0mm) to enhance its durability.
(7) Control panel consists of x-ray controller and communication cable. So it can dealt
the X-Ray irradiation and control from the long distance. LCD display allows the
operator to irradiate at best X-ray irradiating conditions.
(8) Table and stand are connected into one single unit. Therefore, no extra stand rail
work is needed. Table moves in four directions to provide easy-positioning.
(10) X-ray Controlling device and high voltage radiation device are all built in one unit.
Therefore, it is easy to convey and possible to install even in a small space.

(11) PSU(POWER STORAGE UNIT) does not need much power and works efficiently
under 2kW~3kW. Therefore, you could reduce electricity rate and save electricity cost.
(PSU OPTION)
(8) Wide selecting modes allow the operator to combine and create various working
conditions.

4. Using safety Guide
Comed Co, Ltd designs and builds this instrument complying with
related safety requirement.
Only the authorized personnel can remove the covers and/or have access to
the components under tension.
WARNING

anaestethic 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
cause short-circuits.
Before cleaning the device, please disconnect it from the line voltage
Wherever necessary, use the accessories, such the leaded aprons, to protect the
patient from radiation
While performing the radiography, no one, apart from the operator and the patient,
must remain in the room.
Cooling down the storing heating at a radioactivity origin, must follow the
described use cycles.

COMED Medical Systems Co.,Ltd.
WARNING !
Though the X-ray quantity supplied by radioactivity units is quite low and
distributed on a small surface, the operator must adopt the precautions and fit
protections for the patient and himself, during the execution of radiography. It
is advisable to control the X-ray emission from a protected area, by means of
a remote control. If it is necessary to operate near the patient, stay as far as
the cable of the remote control allows it, or at least 2m far both from the X-ray
source and from the patient.
