for too long. Wearing yellow lens glasses can reduce the potential impact.
Bilirubin Photo isomers may have toxic effects.
Water balance: Water balance may be disturbed for some patients.
Photosensitive Drugs: Irradiation may reduce the effectiveness of light-sensitive drugs. Do not
store the medication near light irradiation.
Flammable gas: Do not use the device near combustible gases. (eg oxygen, nitrogen dioxide, or
other anesthetics)
Power off: When cleaning the light source, always turn off the power and remove the power
cable.
