4.4 Zooming In and Out (Agilo Camera only)
Press the zoom in button ( ) or zoom out button ( ) on the keypad to
increase or decrease magnification respectively. A magnifier symbol will
appear on the bottom of the screen to indicate the zoom operation. The
zoom buttons will only operate in Camera or Split mode.
4.5 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 Picture mode. If you wait for at
least three seconds and press the button again the image will revert
back to the last used reading mode. However if you press within this
time period the negative image of the last reading mode used (including
semicolors) will be displayed. Another press will select the positive
image and pressing again will revert back to picture mode.
4.6 Brightness Control
When the Agilo is in camera mode or PC mode the split control buttons
function as brightness controls. The split left button (
) decreases the
brightness while the split right button ( ) increases the brightness.
You may find that details in some photographs will appear clearer at
different brightness settings.
