Appendix A
Setting the System Speed
There are two methods in changing
tire
system processing speed of your
AL486 VIO-U3. The first method is implemented through the hardware
turbo switch J2. The second method, software setting, requires the simulta-
neous pressing of several keys on the keyboard known as hot-keys. You
may change the speed during normal operation while working with your application program.
The
hot-key combinations for setting the system speed on your AL486
VIO-
U3 are shown on the following diagrams.
