Controls There are two buttons on the mouse: a mode button and a brightness button. These buttons are replicated on the control box front panel.

Negative mode, which Scroll Zoom displays enhanced contrast white letters on a black background.
several small increments; repeatedly pressing this button will cycle through these levels. If the button is pressed for longer than half a second, it will automatically step up and down through the different brightness levels until released. Scroll-Zoom Control Rotate the scroll-zoom wheel forwards and backwards to select the level of magnification you are comfortable with. Sliding the scroll wheel forwards increases the magnification, while rotating backwards will decrease the magnification.
The overview mode can also be used to orientate your position on a page or to view text or objects in awkward places. Be advised that the further the objects are away from the mouse camera, the smaller they will appear on screen. In overview mode it may be easier to view the image using the photo mode and if needed adjust the brightness level using the brightness button. For writing with your TVi Color see section entitled ‘Writing with your TVi Color’.
Reading with your TVi Color Your TVi Color is easy to use, and with a short amount of practice you should become proficient in its use. Remember, when reading, look at the television, not at the paper or the mouse, as the magnified image appears on the television. Put the full weight of your hand on the mouse. This will reduce fatigue and will give you more control over the mouse's movement. Find the start of the text and slide the mouse smoothly across the line of text.
Writing with your TVi Color The mouse has handwriting stands that can be pulled out that allow you to write with the aid of the camera. Flip out one of the stands: use the lefthand-side stand if you are right handed and vice versa. Rotate the scroll-zoom wheel on the mouse fully backwards i.e. into overview mode. When using the mouse for writing, it is best to use the full color mode.
Important Instructions for Use Use only the power supply adapter provided. Do not use the TVi Color in a bathroom, near water or other damp conditions. Do not open the TVi Color- there are no user serviceable parts inside and opening it will invalidate your warranty. Hints and Tips • If the text you are reading is not as clear as you would like, try pressing the brightness button to step through the settings. One of the levels of brightness should produce a better image.
