9. Miscellaneous Information
Guidance and Manufacture's Declaration for Electromagnetic Emissions
The curing light is intended for use in the electromagnetic environment specified below. The customer or user should ensure that it is used in such an environment.
Emissions Test
RF emissions
CISPR 11
RF emission
CISPR 11
Harmonic emissions
IEC 61000-3-2
Voltage fluctuations/flicker emissions IEC 61000-3-3
1) Press the Time/Mode or Power Button to wake from Power Save Mode.
2) Check the red Low Battery Indicator for battery charge status.
3) Check that fresh batteries are correctly inserted into the unit.
4) If red and yellow Warning LEDs are flashing this means the curing light has reached its internal temperature safety limit.
Allow the curing light to cool down for 10 minutes or use a cool moist towel to cool the unit down quickly.
5) If red Warning LED flashes and beeps continuously, call Ultradent Customer Service for repair.
1) Check Mode and Timing lights for correct time input.
2) Check the Low Battery Indicator for battery charge status.
3) Check that fresh batteries are properly inserted into the unit.
1) Check lens for residual cured resins/composites.
2) Using proper amber UV eye protection, verify the LED lights are working.
3) Check power level with light meter. If using a light meter, Ultradent recommends checking the curing light in Standard
Power mode.
NOTE: The true numeric output will be skewed due to the inaccuracy of common light meters and the custom LED pack the
curing light uses. Light meters differ greatly and are designed for specific light guide tips and lenses.
4) Check expiration date on curing resin.
5) Ensure proper technique is being followed according to manufacturer recommendations.
1) Make sure batteries are inserted into the charger in the correct orientation and allow batteries to charge for 1-3 hours.
2) If red lights on the charger do not change to green, call Ultradent Customer Service to order replacement batteries and/
or charger.
3) If neither green nor red lights on the charger are visible, call Ultradent Customer Service to order or replace charger and/
or AC adapter.
1) Make sure charger is plugged in and AC adapter is plugged into a working power outlet.
2) If green or red lights on the charger are not visible, call Ultradent Customer Service for new charger and/or AC adapter.
1) Hold both Time/Mode and Power buttons down until a series of beeps indicates the curing light is unlocked.
Compliance Electromagnetic environment - guidance
Group 1 The curing light uses batteries and is not affected by EMI, RF, or surge suppression.
The curing light uses electrical and electromagnetic energy only for their internal
Class B
functions. Therefore, any RF emissions are very low and are not likely to cause
interference in nearby electronic equipment.
N/A
Harmonic emission and voltage fluctuation testing are not applicable to the curing
light because it is battery powered.
N/A
The curing light is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage power supply
network that supplies buildings for domestic use.
