The brakes on the table can be used to restrict the table's movement:

• The rotary knob locks the side-to-side movement.

• The sliding knob locks the in-out movement.

Both brakes operate independently and you may find that locking one or

other allows you to scan a line of text or a column of numbers easily.

Locking both brakes facilitates writing under the unit.

4B. Power button

Press the power button to turn on the unit. Pressing the power button

again (after the start-up screen has cleared) will turn off the unit. The

Eclipse stores its settings only when it is powered off using the power

button. If the power is interrupted, either by a mains failure or by

unplugging the power, any changes made during the session are lost.

4C. Zooming in and out

Press the upper half of the zoom control to enlarge the magnification.

The button can be held until the desired magnification is reached.

When the maximum magnification is reached the key click will change to

a beep and zooming will stop.

Pressing the lower half of the zoom control will reduce the magnification

in a similar manner.

4D. Picture and Reading Modes

Picture mode offers a full colour image suitable for viewing

photographs and other images or for viewing text without enhancement.

There are two Reading modes, positive and negative; sometimes

referred to as normal and reversed. The positive mode enhances the

contrast and removes greys. Negative mode enhances the contrast and

also reverses the ink and paper making the letters white and the paper

black.

The Mode button

is used to select the desired image mode.

Repeated pressing of the mode button will switch from picture mode to

positive to negative and back to picture mode. Select the reading mode

you find easiest to use.
