SAFETY - IMPORTANT PRECAUTIONS
• Please read the whole manual before using the equipment.
• Attention - Using other controls, setting or running not specified in this manual may result in the
exposure to hazardous radiation.
• Attention - Laser smoke may present living tissue particles.
• As the equipment will be used by qualified professional, an additional specific training for its using
is not required. However, the reading of whole manual before its using is recommended.
• If the equipment is not used for some time, the battery shall be removed.

Therapy EC | User’s Manual
• The replacement of the battery by a personnel with inadequate training might result in a danger
(such as excessive temperature, fire or explosion).
• Laser lights may cause eye injuries. People who are on site should protect themselves against laser
lights emission. Therapy EC supplies three green glasses (one for operator, the other for assistant
and the other one for patient). Only glasses supplied by DMC should be used with the equipment.
• Never look directly to laser light. Never direct it for any person, except he/she is on treatment.
• Bright surfaces may reflect laser light towards the eyes.
• Never radiate tumor processes directly, the laser can stimulate them.
• Never radiate the infectious processes directly, the laser can stimulate them.
• Never radiate an undiagnosed injury.
• Never make extraoral application into patients who use photosensitizers medications; any high-in-
tensity light may interact with drug and spot irradiation site.
• Only skilled professionals should handle the equipment. An inappropriate use may bring irrevers-
ible injuries.
• Only components mentioned in this manual should be used together with equipment.
• This equipment cannot be used with power cable not supplied by DMC because it may provoke an
increase of emission or decrease of immunity of equipment.
• To avoid risks of shocks, the equipment should be connected only in grounded outlets.
• Do not connect power cable in difficult-to-access outlets.
• Disconnect the power cable from outlet by plug.
• No change should be made in the equipment.
• Do not obstruct equipment air input/output.
• Do not apply any protector film on handpiece in order to obstruct air input/output.
• Do not install the equipment directly on sunlight, dusty places or mechanical vibration.
• There are risks of fire and/or explosion when laser exit is used with flammable materials, solutions
or gases or in an environment full of oxygen. Avoid using flammable or oxidizable anesthetic gases,
such as nitrous oxide (N20). Due to high temperatures, some materials, like cotton, when saturated
with oxygen, may be ignited. Adhesive solvents and flammable solutions used for cleaning and dis-
infection should be evaporated before using equipment. Pay attention to the ignition of endogenous
gases.
• The user should be exposed to the equipment noise during a maximum period of 8 hours/day.
• Due to the reduced size of the equipment, some safety items could not be inserted, such as: means
of protection against non-authorized use, control switch and emergency stop for the laser. Thus, the
user shall keep the equipment in a safe and protected place.
EQUIPMENT SAFETY ITEMS
Laser Beam
The equipment uses a low intensity laser beam (red laser) to indicate the infrared laser irradiation
point of the laser therapy handpiece.
As the target beam passes through the same delivery system as the working beam, it offers a good

7
way to check the integrity of the delivery system. If the target beam is not present in the distal end
of the delivery system, if its integrity is reduced or if it seems diffuse, this is a possible indication that
the delivery system is damaged or not working properly.
Alarms
For operator’s safety, during emission of laser light, the equipment sounds an alarm.
Spacer
A spacer is sent to be inserted into the tip of the optical fiber, so as to have a contact application,
i.e., the spacer is an applied part of the product. To replace the spacer, simply pull out the one that
has already been used, clean the equipment and the new spacer, according to item “CLEANING/
DISINFECTING”, and insert it into the end of the optical fiber.
Handpiece Led
When the led of the handpiece is blinking fast, the laser has been activated.

The label below illustrates the notice for laser radiation according to IEC 60825-1.
HANDPIECE
(A) Blue LED: it indicates that the red laser (R) is selected.
When this led is blinking fast, the laser is active and when it is
slow, the battery is charging.
(B) Blue LED: it indicates that the infrared laser (IR) is selected.
When this led is blinking fast, the laser is active and when it is
slow, the battery is charging.
(C) Left button: it selects the red or infrared laser.
(D) Right button: it selects the energy (in Joules) and the Ilib
technique.
(E) Display: it indicates the dose to be applied in Joules and
the application time in seconds.
