2.3. Description of the unit.
This section describes the physical look of the PLEXTALK and the
layout of the keys and other controls to enable you to locate them
when referred to in later chapters. The names and main purposes
are also detailed here.
Holding the unit carefully, take a few moments to locate the top and
bottom surfaces. The top has 27 rubber keys on it whereas the
bottom has only 5 rubber feet.
Locate the perforated surface of the speaker grill of the PLEXTALK.
Keep the feet downwards and rotate it until the speaker grill is at the
upper right from you. The PLEXTALK should now be set up in its
normal operating position. You can confirm this by feeling the longest
side is closest to you. There should be a narrow, but noticeable,
straight dip in this edge. It is the CD slot.
2.3.1. Top surface.
The PLEXTALK has 27 rubber keys on the top surface. These are
grouped in 5 blocks - a column of 4 keys on the left side, a
rectangular block of 12 keys in the centre, a row of 3 keys below the
rectangular block, a row of 3 keys above the rectangular block and a
column of 5 keys on the right side.
In the column of four keys on the left side, the top key is an ellipse
shaped key and the bottom key is a triangle shaped key. The
remaining two keys in the centre are diamond shaped keys.
From top to bottom, the four keys are:
Menu key - used to access the Main Menu.
Bookshelf key - used to switch media.
GoTo key - used for page and heading navigation.
