Entering a level locked by security
code
For example, return to the Main Menu by
pressing the F4 key twice.
Attempt to enter an enabled level by
choosing the menu line. A new menu will
appear requesting entry of the security
code. Enter the correct code using the
correct sequence of function keys. The
asterisk (*) symbol will appear for each
entry.
If the code is incorrect, the message
“Ready” will appear in the line and access
to the locked level is prevented. If the
code is correct, the display will change to
the locked level after the last digit of the
correct code is entered.
NOTE
Once a locked security level has been
entered, it will remain unlocked even
after exiting to a different security
level. To protect the level, press the F4
(Lock..) key in the Main Menu after re-
turning from the locked level.
