Reading
Reading is best done in positive or negative mode. These modes adapt the image for the visually impaired
to a high-contrast image with improved background. Background and letters can be set at your discretion.
The background can be set by means of background suppression (Vocatex Plus). This will allow you to
filter out the structure of a sheet. This unique KOBA Vision function allows you at all times to set a high
contrast background without annoying paper impurities. A newspaper can be read without annoying paper
impurities. Factory settings will take you back to the original settings.
Watch photos
Photos are best watched in photo mode. This mode is a unprocessed image without contrast
enhancement. By changing the brightness (Vocatex Plus), you can adjust the image so that the photo
becomes clearly visible. Quality is slightly improved when locking the auto focus.
Crafting
Crafting is best done with a small magnification. It is better to select a dark background during this activity
so that the camera is not hindered by large differences in contrast with whatever is darkened by the hands.
Writing
You can also write under your video magnifier. It is best to use a black pen and lined paper and to lock the
auto focus on the paper.

WARRANTY PROVISIONS
The warranty becomes invalid if the video magnifier:
•
Was not used according to instructions or was misused;
•
Was damaged as a result of a fall or impact;
•
Was disassembled or tinkered with;

Was repaired earlier by a non-official service partner.
Consequential loss is under no circumstances covered by the warranty.

warranty provisions explicitly stated above. This limitation to the liability does not imply a breach of the customer's
legal consumer rights or his or her rights vis-à-vis the vendor.
