the right hand side of the pillar.
The control interface contains all the controls of
the i-See HD.

Display modes

Push the knob to switch between photograph modes or high contrast
modes. The last used mode will automatically be selected. Turn the
knob to select different display modes.

Zooming in and out

Turn the knob to the right to zoom in and to the left to zoom out.
5.4

Zoom presets

While reading texts and looking at images, you require a zoom setting
that suits your needs. The i-See HD contains a function that memorizes
these preferred zoom settings for you.
This means that when you switch from the photograph mode to a text mode, the i-See
HD will automatically switch to the last zoom setting you used in the text mode. The
same goes when you switch from a text mode to the photograph mode – the device will
automatically switch to the last zoom setting you used while viewing photos.
5.5

Blocking the autofocus

The i-See HD will always automatically focus on the object on the tableau. However, in
certain situations (like during writing), it can be useful to block the autofocus.
Push the zoom knob to block the autofocus. Turn the knob in either direction to unblock
the autofocus.
5.6

Brightness

Turn the knob to the left to decrease or to the right to increase the
brightness of the image on your screen.
