Activating and Deactivating the Light

Briefly press the START button; the light will turn on.
- The LEDs first indicate the set exposure time; all
4 LEDs light up for 20 sec. Every 5 sec, as the
time runs down, the LEDs will turn off one at a
time; at 15 sec remaining time, 3 LEDs will still be
on, at 10 sec remaining time 2 LEDs, etc.
- The LEDs do not come on at all in continuous mode;
an audible signal is emitted every 10 seconds.
If desired, the light can be turned off by pressing the
START button again before the exposure time is over.
Holding down the START button activates the tack-
cure function: the device emits a single short light
pulse which enables the defined curing of Protemp
Crown temporary restorations or a light-curing cement
excess (e.g., RelyX Unicem) to enable easy removal.

Inserting and Removing the Light Guide from/into
the Handpiece
Attach the light guide to the handpiece by inserting it
with a slight rotation until it clicks firmly into place
and there are no gaps between the neck of the light
guide and the handpiece (see picture).
Remove the light guide from the handpiece by pulling
it towards the front.

Positioning the Light Guide

Rotate the light guide into the desired position for
polymerization.
To make full use of the light intensity provided, place
the light guide as close to the filling as possible.
Avoid directly contacting the filling material.
- Keep the light guide clean at all times to obtain full
light intensity.
- Damaged light guides substantially reduce
the light intensity and must be replaced
immediately! Sharp edges may cause serious
injury!

Testing of Light Intensity

Depending on the layer thickness of the filling material
being cured, it is possible to check the function of the
curing light using curing disks for composites:
Place the curing disk on a mixing pad.
Fill your preferred composite into a bore of the curing
disk at least twice as deep as the recommended
layer thickness of your composite.
Cure the composite in the curing disk for the time
recommended by the composite manufacturer.
Scrape off soft material from the bottom of the cured
material with a plastic spatula.
The solid thickness of the cured material in the curing
™
disk divided by two is the layer thickness which can
be properly cured.
If you have doubts about the correct function of your
curing light, clean the light guide and the protection
glass in the light guide mounting hole and ensure
proper fit of the light guide in the handpiece and
repeat the intensity test.
If you have still doubts about the correct function of
your curing light, contact 3M ESPE service.
The curing disk must only be used to test the
function of the curing light! For clinical depth of
cure, please refer to the Instructions for Use of
the filling material.
Commonly available devices for measuring light intensity
can also be used; their measurement values should not
be regarded as absolute values. When such devices
are used, we recommend recording the intensity of the
curing light before its first use and measuring it again at
regular intervals so that any decrease in light intensity
can be detected. The light intensity testing unit in an
Elipar S10 base station has a device for measuring
intensity on a percentage basis.
