Picture 1
6. Operation
6.1 Let the cathode of the battery face down to the battery
compartment, and tighten it to the main unit (See Picture 1).
6.2 Take o the red cap from the optical ber and then insert
the metal part into the front of LED.C, make sure to screw the
ber to the end.
6.3 To install the light hood on as show in picture 1.
6.4 Press the time button to choose the solidication time.4
working time modes are available: 5, 10, 15, 20 seconds.
6.5 Lightly press the mode key. Following three modes are
available.
6.5.1 Full power mode: blue light shine in full power.
6.5.2 Ramping mode: The power of the blue light turns from
weak to stronger, and reaches the highest power in 5 seconds.
6.5.3 Pulse mode: blue light work in the mode of pulse.

4
6.6 During the operation, aim blue light at the position
needing solidication. Press the ON/OFF switch, the LED starts
to work under the selected mode. Then it counts down to “0”
second to end the solidication.

continuously operate the curing light for 10 times under 20s
working mode (even the curing light works less than 20s, it is
counted as a full operation), then it will come into over-heat
protection status. And only after 2-minute sleep, it can restart
working 200s continuously.
7. Cleaning , Disinfection and Sterilization
The cleaning, disinfection and sterilization of optical ber is
as follow.
Unless otherwise stated, they will be hereinafter referred to as
“products”.
Warnings
The use of strong detergent and disinfectant (alkaline pH>9
or acid pH <5) will reduce the life span of products. And in such

5
cases, the manufacturer takes no responsibility.
This device shall not be exposed to high temperature above
138℃.
Processing limit
The products have been designed for a large number of
sterilization cycles.
The materials used in manufacture were selected accordingly.
However with every renewed preparation for use, thermal and
chemical stresses will result in ageing of the products. The
maximum number of sterilizations for optical ber is 500 times.
7.1 Initial processing
7.1.1 Processing principles
It is only possible to carry out eective sterilization after the
completion of eective cleaning and disinfection. Please ensure
that, as part of your responsibility for the sterility of products
during use, only sufficiently validated equipment and product-
specific procedures are used for cleaning/disinfection and
sterilization, and that the validated parameters are adhered to
during every cycle.
Please also observe the applicable legal requirements in your
country as well as the hygiene regulations of the hospital or
clinic,especially with regard to the additional requirements for
the inactivation of prions.
7.1.2 Post-operative treatment
The post-operative treatment must be carried out immediately,
no later than 30 minutes after the completion of the operation.
The steps are as follows:
1. Remove the optical ber from the Curing light Device,and
rinse away the dirt on the surface of product with pure water (or
distilled water/deionized water);
2. Dry the product with a clean, soft cloth and place it in a

6
clean tray.
Notes
a) The water used here must be pure water, distilled water or
deionized water.
7.2 Preparation before cleaning
Steps
Tools: tray, soft brush, clean and dry soft cloth Remove
optical ber from main unit and put it into the clean tray.
Use a clean soft brush to carefully brush the optical ber until
the dirt on surface is not visible. Then use soft cloth to dry the
optical ber and put them into a clean tray. The cleaning agent
can be pure water, distilled water or deionized water.
7.3 Cleaning
The cleaning should be performed no later than 24 hours after
the operation.
The cleaning can be divided into automated cleaning and
manual cleaning. Automated cleaning is preferred if conditions
permit.
7.3.1 Automated cleaning
•The cleaner is proved to be valid by CE certificationin
accordance with ENISO 15883.
▪There should be a ushing connector connected to the inner
cavity of the product.
▪The cleaning procedure is suitable for the product, and the
irrigating period is sucient.

with EN ISO15883. For the specific procedure, please refer
to the automated disinfection section in the next section
“Disinfection”.
Notes
a) The cleaning agent does not have to be pure water. It can

7
be distilled water, deionized water or multi-enzyme. But please
ensure that the selected cleaning agent is compatible with the
product.
b) In washing stage, the water temperature should not exceed
45 °C, otherwise the protein will solidify and it would be
dicult to remove.
c) After cleaning, the chemical residue should be less than
10mg / L.
7.4 Disinfection
Disinfection must be performed no later than 2 hours after the
cleaning phase.
Automated disinfection is preferred if conditions permit.
