Handpiece
• First, insert the electronic module into the handpiece
(Figure 10).
• Next, insert the battery into the rear end of the
handpiece/electronic module assembly (Figure 11).
Light-guide
• Before each use, autoclave the light guide and
handpiece.
CAUTION! Be certain to remove the electronic module
and battery pack from the handpiece.
• Disinfect the eye-protection shield.
• Insert the light guide into the handpiece (Figure 12).
Make sure that the light guide snaps into position.
Mount either the hard or soft eye-protection shield on
the light guide.
• NOTE: For the Detection mode (DT), the use of the hard
eye-protection shield is recommended for improved
visibility.
6. OPERATION
Activating the unit
• Gently insert one battery pack into the rear-end of the
D-Light Pro handpiece after the electronic module is
inserted. You will feel the connector guide the battery
automatically into the “Off position”.
• When resistance is felt, gently push the battery all the
way into the handle. A click will be heard when the
battery pack is completely inserted and correctly
seated in the D-Light Pro handpiece (Figure 11).
• Rotate the cap of battery pack by quarter turns in either
direction, to select the required curing program (Figure
13).
• Adjust the angle of the light if necessary by “rolling”
your pen-like grip.
• Press the start button (Figure 14). Keep the tip of the
light guide as close as possible to the surface of the
material to be cured. Prevent direct contact with the
material. In case of contact, carefully remove remaining
material from the light guide using a plastic spatula.
• The D-Light Pro handpiece may feel slightly warm
during prolonged operation. This is normal.
Curing programs
PROGRAM FEATURES
HP
High Power
Standard curing with dual wavelength featuring a 20 second cycle with high output power (approx.
1400 mW/cm
2
) for maximum effi ciency.
LP
Low Power
Low power curing with dual wavelength featuring a 20 second cycle with approx. 700 mW/cm
2
output, optimal for instance when curing close to the pulp.
DT
Detection
Violet light only featuring a 60 second cycle, for the visualization of fl uorescent restorative materials
and/or identifi cation of bacteria in plaque, fi ssures, infected dentin, etc. (see Indications).
Tone signals
TONE SIGNAL EXPLANATION
1x A curing cycle has started or ended.
1 Quick Tone and
a Flash
10 seconds of curing have been completed.
2x A curing cycle has been interrupted prematurely.
3x
The internal temperature of the handpiece is too high. After 3 minutes pause, the curing light can be
used again.
4x
Too many consecutive curing cycles have been performed (>10), and a short pause is required
(maximum 3 minutes)
5x Battery charge is low. The battery needs recharging.
Quick Tone(s)
Selection of a new program (Battery cap rotation)
HP=1 quick tone; LP= 2 quick tones; DT= 3 quick tones
Radiometer Usage
• Select the High Power (HP) curing program
• To confi rm proper light output, cover the window of
the built-in radiometer in the charging station with
the light-guide and press the start button (Figure 15).
• The green LED response means the light output is
suffi cient for usage.
• The red LED response means that the light output is
not suffi cient for curing. Check troubleshooting
section before contacting technical support.
7. AUTOCLAVING AND CARE OF THE UNIT
• The light guide and handpiece sleeve can be steam-
autoclaved at 134°C (275°F) maximum (Figure 16).
CAUTION! Prior to autoclaving, remove the electronic
module and battery pack from the handpiece by pulling
on the “Mode” ring.
• Clean and sterilize the light guide and handpiece in a
sterilization bag before each patient application.
• Use a validated sterilization process at a maximum
temperature of 134°C and for a time of up to 20 min.
Perform sterilization according to EN 17665-1:2006 and EN
556-1:2001 at 134 °C for at least 3 minutes and use steam
sterilizers that comply with the requirements of EN
13060:2004+A2:2010, class B or S.
• The eye-protection shields (soft and hard versions) cannot
be autoclaved, but should be disinfected using an alcohol-
based disinfectant.
• Remove the battery pack prior to routine cleaning,
disinfection and maintenance of the unit.
• The docking ports of the charging station can be cleaned
with a dry clean brush.
• The charging station, battery, and eye-protection shield
should be cleaned with a soft cloth moistened with
alcohol. Organic detergents such as thinners or petroleum
benzine should not be used. Take care not to get water
inside the charging station or on the contact points of the
battery.
8. TROUBLESHOOTING
If any diffi culty is experienced while operating the unit,
please check below for possible causes of the problem
and suggested corrective actions before seeking further
advice or repair from your point of purchase.
Problem Check Corrective Action
When the start button is
pressed, the light will not
come on.
Is the battery discharged or the charging
status extremely low?
Charge the battery.
Is the battery set correctly in the
handpiece/electronic module assembly? If not, reset the battery in the right position
(refer to section “activating the unit”).
Is the electronic module correctly inserted
into the handpiece? Remove the electronic module and insert it
again into the handpiece
Has an extended period of continuous
irradiation been carried out?
The unit is cooling down. After a minimum a
3 minutes where the device is not in use, it can
be started again.
The battery cannot be
charged.
Is the charging station correctly
connected?
Check to ensure the charging station is
correctly connected to the power supply.
Check if the power supply is correctly
connected to the mains.
Is the battery fi rmly set in the charging
station?
Remove any dust present in the docking ports
of the charging station and insert the battery
fi rmly in the docking port.
