2. Product Information
The light has been manufactured with a super-high luminosity 10 W LED. The light
wavelength of LEDEX
TM
WL-090+ is between 390-480nm and the light intensity
is up to 2400mW/cm
2
. It can cure the composite over 2mm in 2 seconds. These
characteristics especially enable to phenyl propanedione (PPD) and Lucirine TPO
photoinitiator.
LEDEX
TM
WL-090+ dental curing light is characterized by :
•
8 powerful extensive modes including Low, Ramp, Standard, High, Fast Ortho,
Turbo, Plaque inspect and Caries inspect modes.
•
The light guide rod is made from genuine optical fiber and not inferior acrylic
that optimizes light conduction and minimizes loss of light from source to tip. It
ensures the highest possible intensity of light at the light guide tip.
•
Advanced and high efficient cooling heat sink are designed and accompanied
with over-heating prevention. A thermal protection circuit and safety mode are
also designed to prevent the light from overheating.
•
The automatic memorization of the last operation is another unique feature of the
light.
•
There is a built-in radiometer displaying light intensity.
•
Automatic sleep mode saves battery and extends usage time.
2.1. Indications for use
LEDEX
TM
WL-090+ is a visible curing unit programmed for polymerization of
dental light cured materials only by dental professionals.
FOR DENTAL USE ONLY!
2.2. Procedure
Please follow the instruction before use. As for handpiece instructions, please
refer to 2.6-2.7. It is required to use the disposable sleeves to prevent cross
infection.
Put the sleeve and cover the handpiece before operation. After conducting a
surgery on a patient, please take off the sleeve and throw away, as the sleeve is
prohibited to reuse.

2.6. Installation and charging
Startup
When receiving the unit, any damages may occur
during transportation. If necessary, contact your
supplier.
Handpiece
First of all, this product must be cleaned as normal
preparation for each patient to prevent cross infection
(see the chapter 7).
Remove the protective caps from the handpiece which
should be kept whenever not in use to prevent liquid
from damaging the LED. Next, insert the light guide into
the handpiece and ensure the light guide is properly
inserted.
Battery
We recommend you to charge the battery fully before
the first use.
Put the battery into the handpiece and rotate clockwise
until you hear a “click” sound and feel the battery
clicked into the right place.
Ensure all the segments of the display are shown. The battery supplied is only charged
to about 60% prior to shipment. Each time, charge it fully before using it.

•
While using plaque or caries inspect, please put on 5 mm light guide rod, it
is the best size to check plaque and caries in dark environment and observe
the pure violet wavelength output through FIND
TM
optical filter, you can see
easily and immediately where excavation of caries is.
•
While using plaque or caries inspect, please turn off dental unit lamp and
reduce ambient light of clinic, it will avoid other sources of light to ensure that
the distinction between red and green fluorescence is clearly maintained.
The plaque & caries area will be displayed on red fluorescent results.
•
While using plaque or caries inspect, patient can hold the FIND
TM
Mirror,
patient is easy to see their plaque or caries via the mirror.

When LEDEX
TM
WL-090 is operated frequently for long
period of time, the temperature may become too high.
Therefore, the “Safety” mode function will then be activated
automatically to prevent the light from overheating. The
safety mode cuts the light intensity in approx. half and
extends the irradiation time.

4.1. User
4.2. Ambient conditions

The LEDEX
TM
WL-090+ Dental Curing Light is an electric device
designed to meet the worldwide electrical safety standards, which
includes U.S.A. and Europe, so it’s safe and effective for all dental
applications.
To avoid electric shock:
•
Do not attempt to open or alter the unit in any way. Only the
service centers authorized by DENTMATE can open the unit
housing and repair the device.
•
Do not put any foreign objects into the housing of the unit.
•
Use only the LEDEX
TM
WL-090+ cradle when recharging this
product. Never attempt to use any other devices for recharging.
•
Connect the power plug into a suitably grounded and approved
outlet. When you use an extend cable, make sure the grounded
line is not interrupted.
•
Always unplug the charging dock before disinfecting.
•
Never use the power supply if the cord has been damaged.
4.3. To avoid electric shock (shock hazard)
As it is the case with all high-performance lights, the high light
intensity results in a certain heat development. Prolonged
exposure near the pulp and soft tissues may result in irreversible
or reversible damage. Therefore, this high-performance curing
light must be operated by trained professionals.
4.4. Heat development (burn hazard)
Use only original spare parts, particularly DENTMATE batteries
and charging bases. Do not short circuit battery. Do not store at
temperatures above 40 °C / 104 °F(or 60 °C / 140 °F for a short
period). Always store batteries charged. The storage period must
not exceed 6 months. It may explode if it’s disposed of in fire.
4.5. Battery
Note : At least 10 mm gap between soft tissues and optical fiber
light guide rod.

5.1. During operation, the light should be aimed straightly on the resin to ensure
solidification effectively.
5.2. Never aim the light directly at unprotected soft tissues because this may lead to
injury or irritation. Do not aim the light at eyes. Light reflected from the tooth surface
may also injure eyes. Use the protective shield supplied with the unit or suitable,
light filtering safety glasses.
5. Precaution
Problem Resolution
Can not turn on the handpiece
Remove the battery and insert it again. If the
error
persists, please plug-in the power supply to
cradle and charge the battery at least 10 mins.
Then push the ON/OFF button again.
Can not charge the battery Please clean battery contacts. If the error
persists, please change a new battery.

please wait a moment and then use it again.
Display shows “Error 1” sign LED module is unnormal, please call your
qualified technician.
The intensity is too low
If the result of intensity test in Standard mode
is under 700 mW/cm

7. Daily Maintenance
Read this entire section before cleaning the unit. This product must be cleaned as
normal preparation for each patient to prevent cross infection.
The use of the sleeve is an additional precautionary measure against contamination
and does not substitute disinfection of the device.
After using, remove the sleeve. Clean the optical light guide rods and the handpiece
with cloth moisture with alcohol or cleaner. Keep solvents or flammable liquids from
the unit because they may damage its plastic housing.
Always keep the charger, handpiece and light guide well. Moisture may cause
electrical short-circuit or dangerous malfunction.
1. The curing time interval should exceed 5 seconds
for each cycle.
2. Verify the radiometer sensor which can impact the
accuracy of the measurement. The surface of sensor
area can be wiped with a cotton swab with alcohol.
3. Carefully hold the unit, so the Light Guide
Attachment is aligned with the radiometer sensor
and centered within the white circle provided.
STANDARD
05
Tips:
Optical fiber light guide must be horizontal
alignment in the middle of the sensor area.
Test the Light Guide Attachment with the Radiometer
Verify the LEDEX
TM
WL-090 performance each time before using the radiometer
which is built into the cradle.
15

4. While holding the unit, press and release the ON-
OFF Button. The radiometer will then provide a reading
of the light intensity on the cradle display.
5. Wait till the light is off before moving the Light Guide
Attachment away from the radiometer sensor.

Notice:
The WL-090 built-in radiometer is only suitable
for measuring 8 mm optical fiber light guide rod.
It will cause incorrect measurement if it uses in
other sizes of optical light guide rod.
