First Aid
Store-bought creams, lotions, or aloe can be applied to affected areas of the
skin. Seek immediate medical attention for skin burns and direct UV
exposure to the eyes.
Microwave Radiation
WARNING: The lamp system utilizes high powered RF microwave energy
generated by a magnetron to provide power to the UV lamp. This
technology is identical to that of residential microwave ovens and like these
ovens can be dangerous if misused. The lamp system is safe provided that
the RF screen and gasketing are intact. Any damage such as rips or holes
in the screen may cause leakage of dangerous amounts of microwave
radiation. The power to the lamp is interlocked to the RF detector and will
shut down if microwave leakage exceeds safe levels. Any excessive
leakage will cause the system to shutdown.
