Parameter
COM/IO LOCK CODE
Lock Code Value Range is 0 - 9999
Units None
Setting The
I/O Lock Code
COM/IO LOCK CODE
This allows changes of STC-2000A program parameters to be restricted to only those people
knowing this 4 digit password code. A non-zero number in the range of 1-9999 enables this feature and
becomes the lock code. If the lock code is programmed with a non-zero value, whenever you access an I/O
Program menu that can change a parameter or try to change a Communications Configuration parameter,
the STC-2000A will ask you for this lock code.
Caution
CAUTION If this lock code is entered inadvertently or forgotten it can be removed by
purging the unit of all its stored parameters. When this is done all program parameters including I/O
programming, System Configuration, Process Lists and Film Parameters will be lost and require
reprogramming. This could be several hundred items of data. All this data should be recorded prior to
purging the memory of the STC-2000A. Recording methods include downloading to a PC from the HOST
port, information written down by making a paper copy of the various parameter tables and circling the
selected element (see end of manual), downloading to the memory module. To purge ALL stored data from
the STC-2000A, press the fixed MENU key when on the RunTime screen then select the Service key on
the MAIN menu. Press the Purge (All Stored Data) key and the confirming ACCEPT key. After doing
this the STC-2000A will contain no user programmed information and will have to be completely
reprogrammed. Default values will be in effect elsewhere.
If lock code is forgotten and programming has not been saved in some other
media, call factory to eliminate passwords without purging memory.

Parameter
KEYBOARD BEEP
OFF / ON
Units None
KEYBOARD BEEP
KEYBOARD BEEP
This parameter tells the STC-2000A whether touch screen activity or fixed front panel key activity
will result in an audible sound upon key press. Key release is never annunciated. Various frequencies are
employed to convey different meanings. For example, a low frequency beep indicates an incorrect entry or
a non-existent key area. The STC-2000A audio system has a frequency range of approximately 330 Hz to
10 KHz.
