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.
Push the light guide into the handpiece until it snaps
into position.

Measurement of Light Intensity

The light intensity of the Elipar FreeLight 2 handpiece can
only be reliably determined using the Elipar FreeLight 2
charger! The light testing area is located on the charger
in the area where the handpiece can be placed.
Measurements carried out using the Elipar FreeLight
charger (predecessor of Elipar FreeLight 2), or another
unit will produce incorrect results due to the different
light sources and the varying arrangement of the
components of the units.
Caution!
Measure the light intensity using 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 LED's come ON for approx.1 sec.
- After this period of time, the number of illuminated
LED's is indicative of the measured light intensity:
5 LED's = 100%, 4 LED's = 80%, 3 LED's = 60%,
2 LED's = 40%, 1 LED = 20%.
If the light intensity is below 80% - fewer than
4 LED's are ON - check the light guide for
contamination 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 (3.) if (1.) and (2.) fail to improve the situation,
please contact the 3M ESPE Customer Service or
your retailer.

Low Battery Charge Display

If the battery charge is below 10% due to frequent use
of the handpiece, only a few more exposures will be
possible. The following signs indicate that the battery is
almost empty:
- A short audible alarm is emitted 5x at the
completion of an exposure, and repeated thereafter
whenever any button is touched.
- The 5-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 LED's are automatically turned off as the
handpiece switches to power-down mode.This reduces
the power consumption of the storage battery to a
minimal level. Outside the charger, the handpiece is
also switched to power-down mode, if it is not used 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 - Handpiece

An acoustical signal is emitted
• every time a button is pressed,
• every time the light is turned ON or OFF,
• after 5 sec of exposure time have elapsed (1 alarm
signal), 2x after 10 sec, 3x after 15 sec.
Two acoustical signals are emitted
• every time the power-down mode is terminated by
pressing any of the buttons.
A 2 sec-error signal is emitted, if
• the handpiece over-heats,
• the rechargeable battery is discharged to an extent
that reliable polymerization is no longer ensured.
