safety
Merlin ultra is designed to enlarge and enhance images in order to offer
improvement in the quality of life for people with visual impairment. The
extent to which Merlin ultra can improve the ability to see images depends
on a person’s individual condition and level of visual impairment.
Merlin ultra 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 Merlin ultra for a patient’s individual condition.
Precautions for Use
• Follow all warnings, cautions, and instructions marked on the product.
• Use the Merlin ultra on a stable, level surface such as a solid desk or
table, according to its intended design specifications.

may fall causing serious damage to the unit or bodily injury to the
user.
• Use the Merlin ultra indoors only – it should NOT be exposed to
extreme or rapid changes in temperature or humidity. Do not place the
Merlin ultra near a radiator, heater or areas exposed to long hours of
direct sunlight. These conditions may cause damage to the unit’s

outlet.
• Do not use the Merlin ultra in, near or around water. The Merlin
ultra is not designed to offer protection against contact with liquids
of any kind.
