Operation

Disinfect or autoclave contaminated surfaces of the
curing light, light probe and anti-glare cone before each
use. Furthermore, make sure that the light output permits
adequate polymerization. For this purpose, check the
light probe for dirt or damage and test the light ouput
with the integrated light meter.

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.

Selecting the curing time

Observe the Instructions for Use of the material applied
when selecting the curing time. The following curing
recommendations are valid for selected materials:

The curing recommendations for composite materials
apply to all colours and, if not mentioned otherwise in
the Instructions for Use of the relevant material, apply to
a maximum layer thickness of 2 mm.

Generally, these recommendations apply to situations
where the emission window of the light probe is placed
directly over the material to be polyermized. Increasing
the distance between the light source and the material
will require the curing time to be extended accordingly.
For instance, if the distance to the material is 9 mm, the
effective light output is reduced by approximately 50%.
In this case, the recommended curing time has to be
doubled.

Acoustic signals

Start (Stop) 1 beep
After 10 seconds 1 long beep
After 20 and 80 seconds 1 short beep
After 40 and 100 seconds 2 short beeps
After 60 and 120 seconds 3 short beeps
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.
Light output
If the 10-mm light probe supplied with the kit is used,
the light output is at minimum 500 mW/cm 2 . If one of
the light probes which are additionally available is used
(i.e. 8-mm light probe and 13>8 mm Power-Booster light
probe), the light output changes by such a small degree
that the above mentioned curing times remain unaffec-
ted.

Measuring the light output

The light output of bluephase C5 and the 10-mm light
probe supplied with the kit can be checked with the light
meter, which is integrated in the handpiece holder. For
this purpose, remove the anti-glare cone and place the
tip of the light probe in contact with the light meter
without applying pressure.
The indicator above the light meter lights up green
according to the light output measured. Each lamp
indicates a light output of approximately 200 mW/cm
(see Indicators on the handpiece holder). If the value
measured does not correspond with the expected light
output, proceed as follows:
– Check the curing program selected
– Clean the light meter with a moist cloth
– Clean any dirty light probes which may be dirty (see

Maintenance and cleaning)

– Replace any damaged light probe with a new one
If these measures do not improve the readings, please
contact your dealer or local Service Center.
The light meter is not suitable for measuring the light
output of other light-emitting devices or light probes.
Maintenance and cleaning
Liquids or foreign substances must not enter the hand-
piece during cleaning (electrical shock hazard). Dis-
2 connect the handpiece from the power supply when
cleaning it.

Housing

Wipe the handpiece and handpiece holder with a
standard aldehyde-free disinfecting solution. Do not
clean with highly aggressive solutions (e.g. solutions
containing orange oil or solutions with an ethanol
content of more than 50 %), solvents (e.g. acetone) or
pointed instruments, which may damage or scratch the
plastic. Clean dirty plastic parts with a soap solution.

Light probe

Clean light probes with a disinfectant and a soft cloth.
Carefully remove any possible material residue, such as
composite material, from the light probe with e.g. finger-
nails or a plastic spatula. Do not use sharp or pointed
instruments, as they may scratch the surface of the light
probe and thus reduce light transmission. Light probes
and anti-glare cones may be autoclaved (e.g. 134 °C,
3 bar, 5 minutes).
Check light probes for damage. If the light probe is held
against a light source and certain segments appear
black, then the glass fibres are broken. In this case, the
light probe has to be replaced with a new one.
