Enter a four-digit security code using
digits 0 to 9, A to F. The number
(shown on the display) changes in
ascending order between 0 and 9, A
and F each time the button is pressed.
Each button number (1 to 4)
corresponds to each digit (first to
fourth) of the security code.
The security code is registered in the
main unit and security is set.
The registered security code is
encrypted and then written to the

ATTENTION
When the security code is registered using
a Memory Stick that contains several kinds
of data, such as music, etc., be careful not
to clear the recorded data by formatting the
Memory Stick.
Refer to "Ejecting the Memory Stick"
on page 27.
