When the system is locked, access to the above menus will be denied unless the
correct password is entered. The Model GC868 is shipped with a
default password
,
which is given later in this section. For increased security, the default password
should be changed.
IMPORTANT: Once the system has been locked, it can only be unlocked by entering
the password, because access to the SECUR submenu is restricted.
To program the SECUR submenu, press [
→
] and [F1] at the Global PROGRAM prompt.
Refer to Figure A-4 on page A-4.
IMPORTANT: It is recommended that all program parameters be recorded before
changing the password. (This information should be recorded in
Appendix B, Data Records, as a matter of routine.) If the password is lost,
the site data is not retrievable and will have to be re-entered.
