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’.
Special functions
Sounds ON/OFF
When a button is pressed the TVi color will emit a tone,
signaling its activation. To disable or re-enable these
tones, switch off the TVi Color and switch it on again
while keeping the brightness button pressed in. The TVi
remembers this setting.
Factory Default Settings
If the TVi Color doesn't respond the way you expect it to,
or if you are unhappy with the current settings, the TVi
can be reset to the default factory settings by switching it
off and switching it on again while keeping the mode
button pressed in.
