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 simul-
taneously 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 this purpose, press the blue volume button (see Product
overview) while the light is off and reduce the volume or
turn the acoustic signals off with the left time selection
button. If you want to turn the acoustic signals back on or
increase the volume, press the blue volume button and
then the right time selection button.
Light intensity
The light intensity is maintained at a consistent level during
operation. If the supplied 10>8 mm light probe is used, the
light intensity has been calibrated to 2,000 - 2,200 mW/cm
2 .
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 win-
dow. 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 20i and the supplied
10>8 mm light probe can be checked, for instance, 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 light sensor if it is contaminated
• Remove the light probe and clean the light emission
window of the handpiece with a cotton swab dipped in
alcohol
• Clean light probe if it is contaminated
(see Maintenance and cleaning)
• Replace a damaged light probe with a new one
If these measures do not improve the results, please con-
tact your dealer or your local Service Center.
