2. Operating voltage
Before switching on the unit, make sure that
a) the local power supply complies with the voltage
indicated on the rating plate
and
b) the unit has acquired ambient temperature.
3. Indications of compromised safety
If there is any doubt about safe operation being
certain, the unit must be disconnected from the power
supply and secured against accidental operation. Safe
operation may be impaired if, for example, the
apparatus is visibly damaged or no longer works
correctly. The unit is only completely disconnected
from the power supply if the power cord has been
pulled out of the plug-in socket.
4. Disinfection and sterilization
Contaminated surfaces of the apparatus, light probes
and anti-glare cone must be disinfected or autoclaved
before each use.
5. Light output
Before each use, make sure that the light output
permits adequate curing. For this purpose, check the
light probe for contamination and damage.
6. Heat development
As it is the case with all polymerization lights, the
high light output results in a certain development of
heat. Prolonged exposure of the pulp and soft tissues
may result in damage. Therefore, uninterrupted curing
times of more than 40 seconds in the same area, as
well as direct contact with the gingiva, oral mucous
membrane, or skin have to be prevented. Prevent heat
accumulation when polymerizing with a rubber dam in
place.
7. Eye protection
Direct or indirect exposure of the eyes must be
prevented. Prolonged exposure to the light is un-
pleasant for the eyes and may result in injury. It is
therefore advisable to use the anti-glare cones
provided. Individuals who are generally sensitive to
light, who take photosensitizing drugs, or who have
undergone surgery and people who work with the
apparatus or in its vicinity for long periods of time
should not be exposed to the light of this device and
wear protective goggles that absorb light below
515 nm.
8. Maintenance and cleaning
Any repair work must only be performed by a certified
service center. Liquids or any foreign substances must
not enter the handpiece, handpiece holder and parti-
cularly the power pack during cleaning (electrical
shock hazard).
9. Disposal
Do not dispose of the apparatus with normal domestic
waste. Dispose of curing lights according to the
corresponding national rules and regulations.
Start-up
Start
The light is activated by pressing the start button and
switches off automatically after 2 minutes. If you wish to
switch off the light before the set curing time has
elapsed, press the start button again. The fan is switched
on at the same time as the light is activated. After the
curing cycle has ended, the fan continues to run for some
more time. The power pack must not be disconnected
from the power supply as long as the fan is running.
Curing times
Observe the Instructions for Use of the material applied
when selecting the curing time. In general, a maximum
curing time of 20 seconds is valid for light-curing
adhesives and a maximum of 30 seconds for composites
with a layer thickness of up to 2 mm.
Acoustic signals
Start (Stop)
After 10 seconds
After 20 and 80 seconds
After 40 and 100 seconds
After 60 and 120 seconds
If preferred, the acoustic signals can be turned off. To
turn off the acoustic signals, press and hold the start
button for approximately 30 seconds while the light is
off. To turn the acoustic signals back on, press and hold
the start button for another 30 seconds while the light is
off.
