Changing The Processor Speed - Epson Pollution Preventer User Manual

Note
Some hard disk drives do not support a low-power standby
mode. Also, the delay caused by the hard disk drive
returning to active mode may cause errors in some
applications. If you have problems, you may want to disable
the standby mode for the hard disk drive.

Changing the Processor Speed

Your computer's processor can operate at two speeds: fast or
slow (8 MHz). The slow speed is available to provide
compatibility with older application programs, such as those
that require you to leave a key disk-the diskette that contains
the copy protection-in the diskette drive.
When your computer is operating at fast speed, the SPEED light
on the front panel is on. When the computer is operating at
slow speed, the light is off.
You should use fast speed for almost everything you do
because your programs will work faster. However, certain
application programs have specific timing requirements and
can run only at the slower speed. See your application software
manual to determine if this is the case.
You can change the processor speed temporarily by entering
one of the following commands from the numeric keypad on
your keyboard :
