Using the Color Keys
The red, green, yellow, and blue keys on
your BOOKMAN change functions ac-
cording to which book is selected.
When the built-in book is selected, the
color keys function as labelled on the
BOOKMAN keyboard. When a car-
tridge book is selected, the color keys
function as labelled on that cartridge.
Remember, the color keys for BOOK-
MAN books in cartridges function as
labelled on their cartridges, not as on
the keyboard.
AC adaptor jack: Your BOOKMAN
may be equipped with a standard 3.5
mm jack for use with a 9-volt, 200-300
milliamp AC/DC adaptor.
This symbol indicates that the inner
core of the plug of an AC adaptor is
negative and that the outer part of the
plug is positive. If your AC/DC adap-
tor does not have this symbol, con-
firm its compatibility at its place or pur-
chase.
Headphone jack: Your BOOKMAN
may also have a 3.5 mm stereo head-
phone jack for use with a standard im-
pedance 8 Ohm headset.
