Indicators.
The following indicators are provided on the control console to signal curing light fault:
• LED 5 and LED 1, green, steady on.
Lamp does not emit any light.
Contact technical service department.
• LED 5 and LED 2, green, steady on.
Instrument start up microcontroller fault.
Contact technical service department.
• LED 5 and LED 3, green, steady on.
Power supply too low.
Contact technical service department.
• LED 5 and LED 4 flash continuously.
Handpiece cut-out tripped. These LEDs will continue to flash until the light has cooled down enough (about 5 minutes) to be used again.
If the problem persists, contact technical service department.
Maximum curing thickness.
The maximum curing thickness with every single cycle is 3 millimetres (refer to the instructions of the composite material used as well).
The LED is a Class 2 light source in accordance with IEC 62471 standard. DO NOT STARE AT THE BEAM.
The light emitted may cause eye injury in case of direct radiation without eye protection.
Always use an eye protection shield when operating the curing light and do not direct the light beam to the eyes.
The light emitted may damage soft tissues (oral cavity mucous membrane, gums, skin).
Be extremely careful to aim the light precisely on the material to be cured.
• People with eye diseases, such as those who have had cataracts removed or retina diseases must be adequately protected when the curing
light is used, for example with suitable protective eyewear.
• The rotary end can turn 180° counter-clockwise in relation to the handpiece to change from wand to gun configuration.
To go back to wand configuration, turn clockwise.
A click is heard when these two positions are reached. Do not turn any more once the click is heard.
The intermediate positions can be used even if a click is not heard.
Put the fiber optics back into the correct position after turning the end section.
• Do not pull the power cord.
• Do not expose the handpiece to excessive vibrations.
• Do not drop the handpiece and in particular the fiber optics.
The lamp may break if accidentally banged.
Check the condition of the handpiece if it has been banged or dropped before using the curing light.
Try to turn on the light and check operation first without using it on the patient.
If cracked, broken or if there are any other faults, do not use the curing light on the patient and contact the technical service department.
The fiber optics is rather delicate and may crack or break if banged, affecting the final amount of light emitted.
If dropped, carefully inspect the fiber optics to verify if it is cracked or broken. If cracked, a strong light appears in the spot in which the fiber is cracked.
In all these cases, the fiber optics must be replaced.
• The curing light handpiece (sold separately) can be connected only to dental units with connections for this curing light handpiece.
Connection to any other equipment may damage the circuits inside the lamp and seriously injure the user and patient.
• The curing lamp handpiece is not protected against liquid penetration.
• The curing lamp handpiece is not suitable for use in the presence of flammable anaesthetic gas mixed with air, oxygen or nitrous oxide
(N
2
O).
Cleaning.
The curing light may be a means of cross contamination between patients.
The most contaminated parts are the fiber optics and the eye protection. Before sterilising them, make sure there are no residues of curing products: if
necessary, clean with alcohol or a plastic spatula.
Exclusively sterilise the optical fibre and the eye protection in an autoclave at a sterilisation temperature of at least 134°C.
