TEXT ENTRY
The user is often required to enter text characters or numbers (when editing operator notes, for example). This
is done using the pop-up keyboards which are displayed when required. When only numerals are required a
special keyboard is presented which contains only numerals.
Figure 36 shows the three standard keyboards, along with a 'scan' direction for operations of both up arrow and
down arrow keys. To change keyboards, use the arrow pushbuttons to highlight the keyboard name ('Numeric',
'Symbols' or 'Alpha'), and then operate the scroll button.
Generally, to enter text, the required character is highlighted using the up and down arrows and the scroll button
is used as an 'Enter' key. Once text entry is complete, the Page button is used to confirm the edit (use the down
arrow to select 'Yes' then operate the scroll button).
Pressing and holding the scroll button and then immediately operating the up or down arrow, causes the
character insertion point to move to the left (down arrow) or to the right (up arrow).
The user can press and hold the scroll key to display variations on certain characters (the letter 'e' in the figure).
Once displayed, the up and down arrows can again be used to scroll through auxiliary list, allowing capital
letters, and characters with diacriticals (e.g. accents, umlauts, tildes, cedillas) to be selected and entered using
the scroll button.
