Exposure times of 5,10,15, and 20 seconds are available.
For the compatible product at hand, use the exposure
time as stated in the product's Instructions for Use
and reduce to half.
Select the exposure time by pressing the "sec" button.
- The selected exposure time is indicated by the
4 green LEDs.
- Each time the button is pressed, the setting
advances to the next (higher) value; after
20 seconds the exposure time setting returns to
5 seconds. Keep the button depressed to scroll
through the available settings.
- The button for selection of the exposure time is
deactivated during light activation.

Activate the light by briefly pressing the green Start
button.
- Initially, the LEDs show the preset exposure time:
4 illuminated LEDs represent 20 seconds of
exposure time. After every 5 seconds of exposure,
one of the LEDs is turned off (e.g., 3 LEDs
correspond to 15 seconds of exposure time
remaining, 2 LEDs to 10 seconds of exposure
time remaining, etc.).
If it is desired to turn off the light before the preset
exposure time has completely elapsed, press the
green Start button again.
Positioning the Light Guide
Rotate the light guide into the optimal position for
polymerization.
To make full use of the light intensity provided, pla-
ce 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.
Removing and Inserting the Light Guide from/into
the Handpiece
To remove the light guide from the handpiece pull
towards the front of the device.
To put the light guide into the handpiece, push the
light guide in until it snaps into position.
Measurement of Light Intensity
The light intensity can be reliably determined only with
the charger of the Elipar FreeLight 2 unit. The light
testing area is situated on the charger base. Testing
the light intensity with any other unit produces
erroneous results because of differences in the light
sources used and arrangement of the components.
Caution: Measure the light intensity with the 8 mm
turbo light guide only.
If required, clean the test area with a wet cloth.
Take care not to bend or damage the charging
contacts.
Without applying pressure, place the exid tip of the
light guide level with the test area.
Activate the lamp by pressing the green Start button.
- All 5 blue LEDs come ON for approximately
1 second.
- 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%.
