1. Press the Time/Mode Change Button or Power Button to wake from Power Save Mode.
2. Check that both cords are firmly connected together and to the electrical outlet.
3. Confirm power to the wall outlet.
1. Check Mode and Timing lights for correct time input.
2. Confirm all cord connections are fully seated.
3. Unplug and re-plug power cord into the electrical receptacle.
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 VALO 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
VALO 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 (adhesive/composite) by manufacturer recommendations.
Hold both Time/Mode and Power buttons down until a series of beeps indicates the curing light is unlocked.
