IMPORTANT SAFETY PRECAUTIONS

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.

• Always place the power cord away from traffic areas to avoid
damage of power supply.

• Prevent the risk of electrical shock by NOT attempting to
disassemble the unit. Please refer all service to an authorized

repair facility.

the product.

• The attached power cord is a disconnect device for electrical

equipment. The socket-outlet should be installed near the
equipment and be easily accessible.

• This product is equipped with a 3-wire grounding type plug as a

safety feature. This plug has a third (grounding) pin and can only
be plugged into a grounding-type power outlet. If necessary,
contact an electrician to replace your power outlet with a
grounding-type power outlet.

• Do not use the DaVinci in, near or around water. The DaVinci

is not designed to offer protection against contact with liquids
of any kind.

Important Safety Precautions

7

•

This product contains moving
parts. Please use caution when
moving the adjustable slide arm or
when transporting the DaVinci to
avoid possible injury to hands and
fingers.

•

To avoid personal injury or damage
to the DaVinci, do not make any
other type of connections to the
input jacks.

Susceptibility to Interference

There may be temporary degradation of the image when the DaVinci is
subjected to a strong radio frequency field, electro-static discharge or
transient electrical noise. An electro-static discharge (caused by static
electricity) may cause the screen to go blank. If this happens, disconnect
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.

•

Placement of equipment: The DaVinci should not be used adjacent to or
stacked with other equipment.
