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.
Only use the battery supplied with the product. If the battery needs
to be changed, please contact LVI.
Be careful not to catch your fingers when collapsing the camera
arm.
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.

6.5 Extra voices on a USB stick
It can be possible to use voices that are on an external USB drive. To

and wait until the unit says “voices are ready to be used”. It is then
possible to go into the menu and change voices and language settings
to one of the new voices.
6.6 Quality of OCR conversion
In order to optimize the results of the OCR conversion, you should bear
in mind the following.
Make sure that the text is large enough. If the text is too small, the
OCR results will be bad. At least 12pt is recommended.
Avoid glossy paper as this results in reflections in the image. This
impairs the results of the OCR conversion. If you intend to use
glossy paper, we recommend that the light on the unit is switched
off.
Certain fonts can be difficult for the OCR engine to interpret.
It is important that the text contrast is sufficient.
It is important that the chosen spoken language is the same as that
of the text.
The paper should be rotated as little as possible.
6.7 Maintenance charging
MagniLink Voice with a battery is also equipped with a smart battery
charger that uses maintenance charging to keep the battery in good
condition. To further extend battery life, we recommend that you use
your MagniLink Voice once a month with just the battery (disconnect the
mains adapter) until the battery is completely discharged.

MagniLink Voice

7Working with reading machine
Your reading camera is now ready to use. It is important that the
workplace around your MagniLink is comfortable, and that you sit
correctly. This is so that you can use the camera for as long as possible
without putting undue strain and stress on your neck and back.
You should bear the following in mind:
Your chair should be positioned close to the table on which the
equipment is located, and you should not sit in the chair for too
long. We recommend a good office chair with adjustable height.
The seat of the chair should be at a height that does not cause your
legs to become numb; legs should be at an angle of 90 degrees
and you should rest your feet on the floor.
The reading table should be at a height at which you can rest your
lower arm horizontally on it. It is important that the table is neither
too high nor too low for you. The ideal solution is if the screen is
slightly below eye level and in as straight a line in front of you as
possible.
Shield off daylight. Lights in the ceiling, table lamps and light from
windows can cause reflections on the monitor. For this reason,
avoid placing lights where they shine directly at the screen or at
yourself.
If you use the device for long periods of time, there is a risk of
repeated movements causing you pain in your neck, shoulders and
back. Your eyes can also get tired from looking at a screen for too
long.
