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
Andromeda 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 color 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 grays. 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.
