Introducing MagniLink Vision TTS

Thank you for choosing this video magnifier. Our aim is for you to be satisfied with your choice of supplier and reading aid.
MagniLink Vision TTS is a combined reading camera and reading machine. The reading camera includes features such as autofocus, several artificial colours and the potential to set the magnification. The reading machine makes it possible to OCR-process a text and have it read aloud.

MagniLink Vision meets all the requirements for CE marking of medical devices in accordance with Directive 93/94/EEC. Our products comply with MDD 93/94/EEC with additions from Directive 2007/47/EC.

Safety 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.

Unpacking

The system is supplied in a box with the following contents:

• Combined reading machine and reading camera
• User Guide
• USB memory stick
• Power adaptor
• Hand control

Check first that the box has no external damage. In the event of damage, contact the delivery company and file a notification of damage.
Open the box and take out the MagniLink Vision; remove the packaging.

4.1 Packaging
The packaging consists of the following packaging material (LVI recommends that the packaging be kept in case you have to return the system or you need to move it):

• Packing material (EPP)
• Box (corrugated cardboard)
• Polyethylene (LDPE4)

For sorting and collection of packaging material, please call the packaging collection customer service department for information on the rules that apply in your municipality.
Note that the product and its accessories must be recycled as electronic waste. A worn-out battery is recycled as electronic waste.

Installation

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.

Use

To enable the voices, connect the USB stick to one of the unit’s USB ports 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.

6.7 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.

Ergonomics

It is important that the workplace around your system is comfortable, and that you sit correctly. This is so that you can use it 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 out 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.

Troubleshooting

No image is displayed after you start the system:

• Check that the power is on.
• Check that all connectors are properly connected as explained in the `Installation’ section.

The LED to the left of the start button shines red:

• Something is wrong and MagniLink Vision cannot be used. Press the start button once and MagniLink Vision will make three attempts to restart. If the system still fails to start, the LED will shine red again. Disconnect the power cable and contact service personnel.

The LED flashes red:

• The incorrect voltage is being supplied from the mains adapter. If the fault persists, disconnect the power cable and contact service personnel.

If the unit gives the voice response No text in the document after an OCR conversion.

• Check that the document is not rotated through more than 15 degrees.

Never remove any panels or the casing in order to attempt to repair the system yourself. In the event of problems, contact your local dealer.
