If you use the following switch settings and power the instrument up again,
the instrument firmware stays in the resident part, that is, it is not operable as
a spectrophotometer, but only uses basic functions of the operating system,
for example, for comunication and so on.
To return to normal operation, set switches back to your GPIB or RS 232
configuration settings.

Use the following tables for selecting the setting which you want to use for
RS232 comunication. The number 0 means that the switch is down and
