For your safety and to obtain the most benefit from the DaVinci, please
read these safety precautions very carefully.
The DaVinci is designed to enlarge and enhance images and read print
aloud in order to improve the quality of life for people who are visually
impaired. The extent to which this product can improve the ability to
see images depends on a person’s individual condition and level of
visual impairment.
The DaVinci is not designed to restore vision, correct eye conditions or
halt degenerative vision loss. An eye care professional can determine
the usefulness and suitability of the DaVinci for a patient’s individual
condition. Please follow these safety precautions:
• Use the DaVinci on a stable, level surface such as a solid desk or table,
according to its intended design specifications.
• Avoid placing the DaVinci on an unstable table, cart or stand. It may
fall causing serious damage to the unit or bodily injury to the user.
• Use the DaVinci indoors only – it should NOT be exposed to extreme
or rapid changes in temperature or humidity. Do not place the
DaVinci near a radiator, heater or areas exposed to long hours of
direct sunlight.

the AC power from the electrical outlet, wait 30 seconds, and connect the
AC power again.
Compliance Warnings
• Electromagnetic compatibility: The use of accessories and cables other
than those specified by Enhanced Vision may result in increased
emissions or decreased immunity of the DaVinci.
