You can order all versions of the CK30 keypad with an
international overlay. The international overlay supports English
and many Western European languages, such as French,
German, Italian, Portuguese, and Spanish. You enter all of the
characters and functions printed above the keys just like you
would on a standard keypad.
Note: There are hidden characters (such as { and }) on each
CK30 keypad that require using the color-coded keys to access
them. For help accessing these hidden characters, see “Typing
Characters Not Printed on the Keypad” on page 152.
