Dip Switch Set 1 (Internal Operations - Epson 10020 User Manual

Note
Set the DIP switches only while your computer is off.
Because software programs check the settings each time you
cum on the system, do not change the settings while a
program is running.
Your computer has two sets of DIP switches; set 1 contains
eight switches which control the computer's internal
operations, and set 2 contains four switches which control the
parallel and serial ports. The label inside the DIP switch cover
shows the function and factory setting of each DIP switch.
A switch is ON when it is up and OFF when it is down. To
change the setting, use a hard, thin object, such as a small
screwdriver or a pencil.
