Transformer HD for a patient’s individual condition.
Precautions for Use
• Follow all warnings, cautions, and instructions marked on the product.
• Use Transformer HD on a stable, level surface such as a solid desk or table, according to its
intended design specifications.
• Avoid placing Transformer HD on an unstable table, cart or stand. It may fall causing serious
damage to the unit or bodily injury.
• Use Transformer HD indoors only – it should NOT be exposed to extreme or rapid changes in
temperature or humidity. Do not place Transformer HD near a radiator, heater or areas
exposed to long hours of direct sunlight. These conditions may cause damage to the unit’s
electronics or optics.
• At least once per week, clean Transformer HD with a soft dry cloth or an electrostatic dusting
cloth. DO NOT use liquid cleaners on its plastic surfaces. No additional methods of sterilization
or cleaning are recommended or required.
• Do not use Transformer HD near flammable materials or liquids.
Additional Mechanical Safety Precautions
Your Transformer HD features an adjustable Camera Arm. It has a variety of usable

Caring for Transformer HD
 Always turn the power OFF by pressing the green power button on the front of the device
for five seconds when Transformer HD is not in use and not connected to External Power.
 Optionally you may also place the device into “Standby” state which is a power saving
mode by pressing the green power button for less than 5 seconds or by disconnecting the
HDMI or USB 3.0 cable from the Transformer.
• Ensure that your Transformer HD is completely OFF before cleaning.
• Clean Transformer HD with a soft dry cloth or an electrostatic dusting cloth. DO NOT use
liquid cleaners on its plastic surfaces.
• To prolong the life of Transformer HD remove the battery from the device if it will not be in
use for one week or more.
• The protective glass covering the camera can be cleaned as needed with the lens cloth
provided within the packaging of Transformer HD. DO NOT use liquid cleaners on the
plastic surfaces. No additional methods of sterilization or cleaning are recommended or
Susceptibility to Interference:
There may be temporary degradation of the image when Transformer HD is subjected to a
strong radio frequency field, electro-static discharge or transient electrical noise. An electrostatic 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.
• This product contains moving parts. Please use caution when moving the adjustable arm or
when transporting the Transformer to avoid possible injury to hands and fingers.
• To avoid personal injury or damage to the Transformer, do not make any other type of
power connections to the input ports besides those indicated in these photos.
Additional Electrical Safety Precautions
• The power supply cord is a disconnect device for electrical equipment. The socket-outlet
should be installed near the equipment and be easily accessible.
• Do not use Transformer HD in, near or around water. Transformer HD is not designed to offer
protection against contact with liquids of any kind.
• Use only the power supply provided with your Transformer HD. Using unauthorized power
supplies may cause serious damage to Transformer HD’s electronic components.
• Using any other power supply than the one provided by Enhanced Vision for Transformer HD
will void the warranty.
• Always place the power cord away from traffic areas to avoid damage to the power supply.
• Prevent the risk of electrical shock by NOT attempting to disassemble the unit. Please refer
all service to an authorized repair facility.
• Please ensure that you make all proper cable corrections illustrated in this manual.
Transporting Transformer HD
• Transformer comes with a convenient carrying case for transport. To prevent the unit from
being accidentally dropped and damaged, always return the transformer to the carrying case
when not in use.
• Disconnect and secure all power and video cables before moving the unit.
• Carry the unit long distances by firmly grasping the Transformer HD Main Body when it is in
the folded position. Do not carry Transformer HD by the Camera Head since this may result in
damage to your device.
Optional Transformer HD Suction Base Precautions and Use Instructions
• As an Optional Accessory Transformer HD can be equipped with a Suction Cup base stand
which allows the user more desk space than the Standard Transformer HD Legs.
• In order for ideal contact the Suction Cup base
should be attached to a smooth surface that is clean
and free from debris.
•The suction cup base should be checked periodically
to ensure that it is still secure if being used on the
same surface for an extended period of time. Failure
to do so may result in the Transformer HD falling over
unexpectedly from insufficient suction force. The fall
could potentially result in damage to the unit.
•Please refer to steps 1 and 2 of the Transformer HD
Suction Base installation guide that is included when
you purchase this accessory. It contains the details of
attaching the suction base to the Transformer body.

achieved by turning the LED lamp on or off in the Transformer HD Toolbar.
-For small OCR Targets such as a business card or letter try placing a clean white sheet of
Paper in the background to eliminate any distracting patterns that may exist in the
Multiple Orientations
-Did you know that your Transformer HD supports all available viewing angles (Portrait and
Landscape)? If your target document is too large or unusually shaped you can reposition it at
another angle this enables you to get the perfect fit within the guide frame.

-Clean polarizing filter on the underside of the OCR camera with the nonabrasive lens cleaning
cloth provided with your Transformer HD (avoid using cleaning solutions).
-Make sure the target material is steady and flat. It might take a few moments for the camera
