supplied with the keyboard are 4 die cut self-adhesive A4 label sheets that may
be printed by most conventional means with whatever legends are required by
the application.
Each type of key top (with transparent key cap) listed in the table at
end of BRIEF INTRODUCTION can be separately purchased in certain
quantities and applied for variety in keyboard layout presentation.
The user may use the
key clip (to be found in the
accessory box) to pull off the
key caps and apply the printed
legend label on the key top then
recap the transparent key cap for
identification.
The user may also use
a flat bladed screwdriver (not

example drawing above.
