Cure Memory function
The last settings used, together with the combination of
curing program and curing time, are automatically saved.
Start
The light is switched on by means of the start button.
Once the selected curing time has elapsed, the curing
program is automatically terminated. If desired, the light
can be switched off before the set curing time has
elapsed by pressing the start button again. The fan is
activated simultaneously to the light. Once the curing
time has elapsed, the fan continues to run for a certain
time to cool the apparatus. The battery must not be
removed as long as the fan is still running.
Acoustic signals
Acoustic signals can be heard for the following functions:
– Start (Stop)
– Every 10 seconds
– Program change
– Curing time change
– Connecting the battery to the charging base
– Inserting battery
– Error message
If desired, the volume of the acoustic signals can be
adjusted. For that purpose, press the blue volume button
while the light is off and reduce the volume or turn the
acoustic signals off with the left program selection but-
ton. If you want to turn the acoustic signals back on or
increase the volume, press the blue volume button and
then the right program selection button.
Light intensity
The light intensity is maintained at a consistent level
during operation. If the supplied 10 mm light probe is
used, the light intensity has been calibrated to
1200 mW/cm
2
± 10%.
The use of a light probe other than the one provided has
a direct influence on the light intensity emitted.
In parallel-walled light probes (10 mm), the diameter is
equal at both ends. In focussing light probes (10>8 mm
light probe, Pin-Point light probe 6>2 mm), the diameter
of the rear end is larger than that of the light emission
window. The incident blue light is thus bundled to a
smaller surface, which increases the light intensity emitted.
Pin-Point light probes are suitable for the polymerization
of confined areas, such as the attachment of veneers prior
to excess removal. For thorough curing, it is necessary to
change the light probe.
Measuring the light intensity
The light intensity of the Bluephase N and the enclosed
10 mm light probe can be checked by means of the
Bluephase Meter.
If the measured value does not correspond with the
expected light intensity, proceed as follows:
– Check the selected curing program.
– Clean possibly dirty light sensor (radiometer).
– Remove the light probe and clean the light emission
window of the handpiece with a cotton swab dipped
in alcohol.
– Clean possibly dirty light probe
(see Maintenance and cleaning).
– Replace a damaged light probe with a new one.
If these measures do not improve the results, please
contact your dealer or your local Service Center.
