→ X12345 CHECKSUM
NOTE: observe the changing checksum of the parameter list as new parameter values are ENTered
(designated by the X prefix). This checksum is an aid to identifying a parameter list (all parameter values
together) as unique. This allows tracking of film numbers to obtain specific results and repeatability.
When system problems occur, film numbers can be checked for integrity by use of this checksum. See
section 3.19, Checksum Validation.
For parameters whose values are not numeric, numerically represented values are selected per their
descriptions on the help line. In the following example, there are three choices to be made: RATE, RATE
DEVIATION, and POWER. The RATE choice is made by pressing the "1" key. The RATE DEVIATION
choice is made by pressing the "2" key. The POWER (PWR) choice is made by pressing the "3" key.
Scrolling up beyond the first parameter wraps to the end of the parameter list. Similarly, scrolling down
beyond the end of the parameter list wraps to the beginning of the parameter list. The beginning and end of
the parameter list is demarcated with a list line having the following " - - - -".
When starting from the main REVIEW FILM MENU screen (see Figure 3.9), pressing the ED
i T key may
generate the following screen if the PASSWORD LOCK# under the SYSTEM CONFIG. key on the
EXECUTIVE menu has a value other than zero (a non-zero value enables the password and is itself the
password). The EXECUTIVE menu key is on the MAIN menu.
Using PASSWORD LOCK, enter up to a four digit lock code as the password. Enter a zero to disable
password entry. Unfortunately, for someone who has forgotten the password, when a password is in force,
the password must be used to change it to zero, that is, to disable it.
Fortunity, for security this is true.
