1. Safety Precautions
PLEASE NOTE!
Prior to installation and start-up of the unit, carefully read the instructions provided herein!
As with all technical devices, the proper function and safe operation of this unit depend on the user’s
compliance with the safety recommendations presented in these operating instructions.
 Before operation, you have to read user manual carefully.
 Refer to Section 10, Cleaning / Disinfecting / Sterilizing for sterilizing instructions.
 CAUTION: This curing unit produces extremely high curing energy output! A significant
increase in curing energy is possible compared with equipment you have previously used. It is
important to obey the following precautions and procedures:
 Do not place light directly on or toward unprotected gingival or skin.
 Adjust your curing techniques in accordance with the increase in curing energy. Some examples
are; decrease curing time, increase composite thickness, increase distance between light guide
tip and light cured materials.
 CAUTION: Do not look directly into the light emitted from this curing unit. Do not use this
device without suitable protective eyeshade for the operator, assistant and patient. Suitable
protective eyeshade should blocks most energy below 550nm wavelength.
 CAUTION: Persons having a history of photosensitive reactions or who are using
photosensitizing drugs should not be exposed to the light from this unit.
 CAUTION: Equipment is not suitable for use in the presence of flammable anesthetic
mixture with air, nitrous oxide or environment full of flammable material.
 CAUTION: Don’t dispose of the battery into fire or take battery apart.
 To protect the light guide, after each curing procedure is completed, the handpiece should
always be placed into its holder.
 To obtain a safety operation, we suggest that check your local AC power supply voltage before
you buy and use this product from oversea.

2. Product Description& Fields of Application
The Ultra-lite 1000E DUAL curing light with blue and violet LED is a light curing unit intended for
polymerization of light cured dental materials by dental professionals. The Ultra-Lite 100E DUAL
incorporates two types of LEDs to achieve broad wavelength with range of 390 to 480nm output to
polymerize virtually all light activated resins in the market and a high power mode to produce super fast
curing effect. The relevant range both for camphor quinine (CQ) and phenyl propanedione (PPD)
containing product. Though the majority of light-curing dental materials are responsive in this range of
wavelengths, it is suggested you should contact the filling material maker to make sure it before use.
Ultra-lite 1000E DUAL curing light is a fast-curing LED light. It emits highest light output at about 2,000
mW/cm² like a Plasma Light. 1 second can cure 2-mm-thick composite specimen. The Ultra-lite 1000E
DUAL with mini handpiece also features:
Palm-size, light-weight handpiece for comfortable hand holding.
A perfect product for dental clinicians with small hand.
Raised and large power switch for activating easily
4 Modes preset
High (High intensity) Low (Low intensity)
Ramp Up (Soft start) Cycle (for orthodontic procedure)
Built-in light checker in the charger
Lithium battery inside supports 500 cycles of 5 second curing prior to re-charging.
360 degree rotatable light tip allows treatment in any part of the mouth

6.3 Light Guide / Handpiece
 Autoclave the light guide
prior to first use.
 Then insert the light guide into the handpiece until it snaps into place.
 Standard fiber optic light guide: 8 mm optic probe
 Prior to the first use, place the handpiece in the charging base to fully load the new rechargeable
battery.
 The orange LED of the charging base flashes; please see also section LED Display of the
Charging Base. Once the battery is fully charged, the orange LED turns ON.
 Note: new batteries attain full capacity only after several charging / discharging cycles.
Therefore, the battery charge may initially be sufficient for a smaller number of exposures
only.

7. Operation Instruction
Activating and Deactivating the Light
► The light will enter “sleep” mode if the unit has not been used for more than 1 minute, the panel
display will turn off to conserve power. If the panel display is not illuminated, simply press on/off
button (the trigger button) to bring it out of the sleep mode.
► Activate the light by pressing the on/off button on the keypad.
► Press the on/off button again to turn off (interrupt) the light before the exposure time is over.
Adjust mode and curing time for the Light
► Always use the settings recommended by the manufacturer of the dental material when selecting
the settings
► Please refer to Chapter 6.4 for more information of mode selection and curing time setting.
► Make sure everyone is wearing the appropriate eye protection.
Position the light guide
► The probe tip shall be used in close proximity to the material to be cured. Avoid actual contact.
The flat end of probe should be parallel to the surface being treated.
► Rotate the light guide into the optimal position for polymerization.
► Place the light guide as close to the filling material as possible.
Avoid directly contacting the filling material!
► Keep the light guide clean at all times to obtain full light intensity.

► Damaged light guides must be replaced immediately, since damaged light guide may strongly
reduces light intensity or injures the patient.
Warning signal
► If the temperature on hand piece is over 50oC, the error code “E2” will show up and buzzer
continuously beep 5 tones until the temperature low than 45oC.
► If the battery voltage runs low, the error code “E1” will show up and buzzer beep continuously 3
tones. Please place handpiece back into charger for recharging.
Note:
 Follow manufacturer's directions for curing times on various materials. It is better to over cure
rather than insufficient cure. Over curing should not harm the restoration.
 If the LED remains activated for an extended period, a safety thermostat will cut off the LED
to protect curing gun from overheating. Normal usage may then be resumed if the handpiece
is idled for an extended period for cooling.
8. Operating Errors And Trouble Shooting
Error Cause and Solution
1. Can not activate the light and no
timer display on handpiece.

Battery runs out of power. Please recharge battery,
and try again.
 If not sure what happen, contact the dealer for
further inspection.
2. Error code “E2” shows up and
buzzer beeps 5 short tones.
 Handpiece is overheat,
please wait for minutes to
have handpiece cooled down. Waiting time can be
shortened if handpiece is cooled by compressor
air.
3. Error code “E1” shows up and
buzzer beeps 3 short tones.
 Low voltage, battery is run out of power. Please
place handpiece back to charging base for
recharging.
4. No indicator on charging base.  Check the power plug connects to power outlet
socket firmly.
 If not sure what happen, contact the dealer.
5. Battery working time is  Battery is exhausted after period use (generally

S-19-01-1110-U0031 V1.2 10
significantly shortened. two years). Please contact the dealer to replace
with a new battery.
 If not sure what happen, contact the dealer for
further information.
Note: We and our authorized distributors will make available on request circuit diagram, component
part lists and other information to assist user's appropriate technical personnel to repair the
light cure units which are designated by us as repairable.
9. Measurement of Light intensity
Measurement of Light intensity
Center optic probe on the detecting window which is located on the charging base. Blue LED on
indicates light intensity is over 500mW/ cm2. If blue LED is still off at intensity measurement, the
curing light should not be used. Firstly inspect battery voltage is low or not. If the battery voltage
is high, inspect the unit for deterioration of LEDs and light guide at the same time.
10. Cleaning / Disinfecting / Sterilizing
……………………………………… CAUTION…………………………………………
 The use of a dry heat oven, incompatible chemical vapor type sterilizing must be avoided as
damage can result to the optic fiber and its binding material.
 Do not use any instruments or abrasives on the ends of optic probe loss of light emission may
result.
………………………………………………………………………………………………………
Between Patients:
Probe shall be cleaned free of saliva or dirt prior to sterilizing. The cleaning consists of wiping the
surface slightly with a cleansing solution and wiping with a dry cloth. Sterilizing by autoclave is
preferred.
Power Unit and Curing Gun
……………………………………… CAUTION…………………………………………
 The power unit shall be unplugged before cleaning and disinfecting the power unit and curing
gun to prevent from electric shock.
