4. Operation
Disinfect contaminated surfaces of the curing light as
well as light guides and anti-glare cones before each
use. Additionally, the light guide can be sterilized using
the autoclaves intended for this purpose (see chapter
Maintenance and Cleaning). Furthermore, make sure
that the stipulated light intensity permits adequate
polymerization. For that purpose, check the light guide
for contamination and damage as well as the light
intensity at regular intervals (see paragraph Measuring
the light intensity).
Selecting the curing program and time
Bluephase G4 is equipped with the following
3 selectable curing times and 2 curing programs for the
different indications. Use the time/program selection
button to adjust the desired curing time and hence the
specified light intensity.
H (High Power Program), 1,200 mW/cm
The following curing times can be selected in the
High Power program: 10, 15 or 20 seconds.
PRE (PreCure Program), 950 mW/cm
The PreCure program is used to tack cure light-curing,
adhesive luting composites (e. g. Variolink Esthetic) in
order to facilitate the removal of excess material. The
curing time of the PreCure program is preset to 2
seconds and cannot be altered.
The PreCure program must not be used for
conventional light-curing!
