Line Marker
A line marker is a horizontal line which can be
made to appear approximately a third of the way up
the screen.
It can be used as a reading guide by positioning the
reading table so that the line marker is just above
or just below the line of text being read. The line
marker is switched on using the "Picture" knob.
The "Picture" Knob
The smaller knob, between the Size and Focus
controls, is labeled PICTURE. It changes the
contrast of the display ONLY if the "Text/Photo"
switch (see below) is in the "Text" position.
Turn the PICTURE knob fully clockwise to enhance
the contrast of the material you are reading, which
can make it much easier to read. When the knob is
turned fully clockwise the line marker will appear.
