1.7 *C MODE -- SECURITY

The *C Mode is used to block access to the
user's program information and certain CR10
functions. There are 3 levels of security, each
with its own 4 digit password. All passwords
are set to 0000 on power-up which disables
security (unless the CR10 has a custom PROM
with the password built in). Setting a password
to a non-zero value "locks" the functions
secured at that level. The password must
subsequently be entered to temporarily unlock
security through that level. Passwords are
stored in write protected memory and affect the
program signature.
When security is disabled, *C will advance
directly to the window containing the first
password. A non-zero password must be
entered in order to advance to the next window.
Leaving a password 0, or entering 0 for the
password disables that and subsequent levels
of security.
Security may be temporarily disabled by
entering a password in the *C Mode or using
the telecommunications L command (Section
5.1). The password entered determines what
operations are unlocked (e.g., entering
password 2 unlocks the functions secured by
passwords 2 and 3). Password 1 (everything

passwords can be altered.
When security is temporarily disabled in the *C
Mode, entering *0 will automatically re-enable
security to the level determined by the
passwords entered.
The telecommunications L command
temporarily changes the security level. After
hanging up, security is reset.
1.8 *D MODE -- SAVE OR LOAD
PROGRAM
