Overview

Overview allows you to easily locate a point of

interest on the page you are viewing. Press and

release the Overview button to make the camera

zoom out fully and revert to full-colour mode. An "X"

is displayed in the centre of the screen as an aid to

location. Place the point of interest under the "X" and

press any key to restore the magnification to the

previous level.

The camera will continuously autofocus to achieve

the sharpest image. However, please be aware that

there is a limited range over which the camera can

focus. Raising the camera too high (greater than

30cms from the base of the camera to the page) or

placing the camera too low (less than 25cms from

the page) will mean the camera cannot focus at high

magnification correctly. If the image does not appear

to be in focus, try raising or lowering the camera to

correct it.

The image brightness can be adjusted to suit your

preference. Press and hold the Mode button for

three seconds and text of the form "Bri: 3" will

appear in the centre of the screen. Use the Zoom

Up and Zoom Down buttons to adjust the image as

desired. Press Mode again to save the setting. The

setting you choose will be saved and used

subsequently for that mode of operation.
