05.0 Battery
The Silverlight is powered by a rechargeable lithium-ion battery already contained inside the handpiece,
with no memory effect.
The Silverlight is equipped with microprocessors that check the battery continuously and maintain the
optimum battery charging parameters.
The handpiece may therefore be placed back into the recharging unit at the end of each treatment and left
there, regardless of the charge of the battery.
05.1 New battery - rst charging
NOTE: The battery of the Silverlight is supplied in a partly charged condition.
To charge the battery completely:
1. Insert the handpiece into its housing in the recharging unit (Fig.5 - Ref.B). The green battery LED will
light up (Fig.4 - Ref.B).
2. The recharging phase has been completed when the green battery LED extinguishes.
05.2 Battery low signal
When the charge of the battery becomes low after frequent use of the Silverlight, the microprocessor will
allow 6 more exposures to be carried out (FAST or SLOW RISE) without any need to recharge the battery.
A battery low state is signaled at the end of each of these six cycles by means of two beeps.
Once the six cycles have been completed, the handpiece enters a battery dead state (see point “05.3”).
Place the Silverlight back into the recharging unit.

06.2 Safety requirements during use
�
DANGER: Never point the beam of light in the direction of the eyes.
�
DANGER: Before each cycle of exposure make sure that the ber optic is tted correctly and
fully into the handpiece.
�
DANGER: Before each cycle of exposure always make sure that the optical protection has
been tted onto the end of the ber optic Fig.7.
�
DANGER: Point the beam of light directly onto the material to be polymerized.
Do not subject the gum or other soft tissues to the beam of light (shield these parts suitably if necessary).
The effect of the light should be limited to the oral cavity and in particular to the sector requiring clinical
treatment.
�
DANGER: Do not short-circuit the electric contacts of the handpiece with metal objects or
liquids (Fig. 6 - Ref. A Ref. B).
�
DANGER: During the rst few seconds of exposure avoid contact of the ber optic with the
material to be polymerized.
Deposits of composite material adhering to and polymerized to the surface of the tip of the ber optic
lower the amount of light transmitted and will therefore prejudice subsequent polymerization operations.
�
WARNING: If the ber optic is damaged or not efcient, this will reduce the intensity of the
light being emitted considerably.
In such cases it should therefore be replaced.
06.3 Instructions for use
The silverlight can be used in two different modes:
- FAST: exposure time of 10 seconds at the maximum light intensity.
- SLOW RISE: exposure time 20 seconds with a gradual increase of the light intensity during the rst
three seconds up to the maximum intensity.
Selecting the FAST exposure mode.
- To start the FAST exposure cycle press the push button on the handpiece briey (Fig.4 - Ref.D). An
acoustic signal will be heard (1 beep).
- After 10 seconds an acoustic signal will be heard (one beep). The FAST cycle has been completed.
Selecting the SLOW RISE exposure mode.
- To start the SLOW RISE exposure cycle hold the push button on the handpiece down for two seconds
(Fig.4 - Ref.D). At the start an acoustic signal will be heard and after two seconds another acoustic
signal to conrm the SLOW RISE cycle beginning.
- After 10 seconds an acoustic signal will be heard (one beep).
- After 20 seconds an acoustic signal will be heard (one beep). The SLOW RISE cycle has been com-
pleted.
After the end of the treatment, place the Silverlight handpiece back into the recharging unit (Fig.5 - Ref.B).
NOTE: Interrupting the cycle.
Both in the FAST and in the SLOW RISE mode, the exposure cycle can be broken off at any time by
