110V / 120V supply only. This unit is built for standard North American household current (110V / 120V). Running it on 220V / 240V with the use of a transformer voids the warranty. Confirm your outlet voltage before powering on.

Notes
Do not place items directly on the tank bottom—always use a basket or rack.
For most jewelry soils, 95% of cleaning occurs in approximately 30 seconds; avoid prolonged runs on delicate items.
Generally safe for gold, silver, platinum, diamonds, rubies, sapphires, amethyst, and citrine.
Do not ultrasonically clean emeralds, opals, turquoise, pearls, amber, ivory, or other porous, soft, or heavily included stones.
Ultrasonics do not remove tarnish.
Do not submerge watch heads; clean metal bands with a holder suspended above the water line.
Operate with the tank at least 3/4 full; warm, pre-mixed non-ammoniated, non-flammable solution performs best.
Degas by running the unit for a few minutes before cleaning for maximum cavitation.
Decant settled solution each morning to reuse the clean upper layer; screen the dregs for valuables and dispose responsibly.
