Epson Endeavor WG - Manual (Page 47)

If you frequently use programs that require low or automatic
speed, use SETUP to change the processor speed. Your new
setting remains in effect until you change it again using SETUP.
See Chapter 2 of the Setup Guide for instructions.
If you use these programs only occasionally, you should use
the keyboard commands or the ESPEED program (described
below) to change the processor speed. These methods
temporarily override the SETUP processor speed setting.
Entering Keyboard Commands
You can change the processor speed temporarily by entering a
command from your keyboard. You can use these commands
only if you have enabled the Software speed change option in
the SETUP program. (Enabled is the default setting.) If this
option is disabled, you cannot use the keyboard commands.
The keyboard speed setting commands are listed in the table
below.
