Positioning the Light Guide
Rotate the light guide into the optimal 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 power and must be replaced imme-
diately, sharp edges may cause serious injury.
Removing and Inserting the Light Guide from/into
the Handpiece
To remove the light guide from the handpiece strongly
pull towards the front of the device.
Push the light guide into the handpiece until it snaps
into position.
Measurement of Light Intensity
The light intensity can be reliably determined only with
the charger of the Elipar FreeLight unit! The light testing
area is situated in the area of the charger accepting the
handpiece. Because of differences in the light sources
used and arrangement of the components, determination
of the light intensity with the light testing components of
other units yields erroneous results.
Caution!
Measure the light intensity with the turbo light guide in
"Standard" exposure mode only!
Clean the test area with a wet cloth, if required,
taking care not to bend or damage the charging
contacts!
Without applying pressure, place the light guide on
the test area such that the light-emitting opening of
the rod is level with the test area.
Activate the lamp by pressing the Start button.
- All 5 blue LEDs come ON for approx.1 sec.
- After this period of time, the number of illuminated
LEDs is indicative of the measured light intensity:
5 LEDs = 100%, 4 LEDs = 80%, 3 LEDs = 60%,
2 LEDs = 40%, 1 LED = 20%.
If the light intensity is below 80% - fewer than
4 LEDs are ON - check the light guide for contami-
nation or defects.
Proceed as follows:
(1.) Clean the light guide, if contaminated; please
refer to the section on "Care" or
(2.) replace the light guide, if defective, or
6
(3.) if (1.) and (2.) fail to improve the situation, please
contact the 3M ESPE Customer Service or your
retailer.
Low Battery Charge Display
After frequent use the battery charge of the device may
drop to below 10%, so that only a few more exposures
can be performed without re-charging. Low battery
charge is shown by several means:
- A short audible alarm is emitted 5x at the comple-
tion of an exposure, and repeated thereafter when-
ever any button is touched.
- The 10-sec-LED of the handpiece begins to flash.
The handpiece should be placed in the charger as
soon as possible to re-charge the battery.
Power-Down Mode
Once the handpiece is placed in the charger, all internal
functions and LEDs are automatically turned off as the
handpiece switches to power-down mode.This reduces
the power consumption of the rechargeable battery to a
minimal level. Outside the charger, the handpiece is
also switched to power-down mode if left unused for
approx.10 min.
To terminate the power-down mode press one of the
three buttons.
- The power-down termination signal (two short
audible signals) is emitted indicating that the
handpiece is ready for operation: the handpiece
displays show the latest selected exposure mode
and time settings.
Acoustical Signals
An acoustical signal is emitted
• every time a button is pressed,
• every time the light is turned ON or OFF,
