devices in accordance with Directive 93/94/EEC. Our products comply
with MDD 93/94/EEC with additions from Directive 2007/47/EC.

3Safety information
Only use the power adaptor supplied with the product. Using an
incorrect type of power adapter may cause damage to the system.
Never operate the product if it has been exposed to water or other
liquids. Damaged or wet product can cause electric shocks or fire.
Place the power cord in such a way that you can neither trip over it
or that crush damages can occur.
Place the system at least 10 cm from the edge of the table. When
moving the reading table, make sure your hands are not below or
behind the reading table, as there is a risk of your fingers
becoming trapped. When the reading table is in its outermost
position, an excessive load can cause the system to tip over,
resulting in personal injury.
If the system has to be moved, do not lift at the screen or reading
table as these are moving parts.
If the product is moved from the cold into a warm room,
condensation (moisture) can form inside the unit or on the camera
lens. To prevent problems with condensation, the apparatus should
be installed in the room at least 30 minutes prior to usage.
If the system requires cleaning, detach all cables. Use a slightly
damp (not wet) cloth to clean the system. Use only water or a
cleaning agent that is intended for monitors and computers.
Do not rely 100 per cent on the results of an OCR conversion; the
OCR engine can misinterpret the text. This is particularly important
to bear in mind when processing sensitive information such as a
medical prescription.
If in doubt, contact your supplier.
Warning
The product is supplied packed in a plastic bag. To avoid risk of
suffocation, keep the bag out of the reach of children and infants.

5Installation
Place your MagniLink Vision far enough in on the table in front of your
seat, but at least 10 cm from the edge of the table. Remember that the
reading table can be pulled out approximately 30 cm in three directions.
MagniLink Vision has a low total weight. It is therefore very important to
position the system in the right place on your table, particularly when you
are using the reading table in its most extended position. An excessive
load in this position can cause the system to tip over.
Connect the power cable to the wall socket and press the start button.
The unit is now ready to be used. The screen can be tilted approximately
10 degrees backwards and lowered 8.5 cm from its highest position. Use
the grips on both sides of the screen and move it to find the desired
position. Release the brakes on the reading table and start using
MagniLink Vision.
The following connection options can be found on the rear of the unit.
1. Port for headphones
Here you can plug in headphones.
2. USB ports
The unit has three USB ports. The hand control must be
connected to one of these ports. If you wish to save or open a
document, you can connect a USB memory stick.
