Set Up Screen Fields
You can hear a high-pitched beep when pressing the Ctrl-Alt-
↑↑
keys and a lower pitched beep when pressing
the Ctrl-Alt-
↓↓
keys. The higher beep results from the higher CPU speed, while the lower beep results from
the lower CPU speed.
Note:
DIP switch I must be on in order to hear the beeps. See Chapter 3 for information on how to set the
DIP switches.
You can display the current CPU speed by using the Speed Utility. See the BatteryPro and Productivity
Software User’s Manual for more information.
Note:
In some cases, the above key functions (Fn-Pause, Ctrl-Alt-Pause, Ctrl-Alt-
↑↑
or Ctrl-Alt-
↓↓
) may
not be effective even when Enable is set on the Set Up screen. In this case, use the system timeout function
or change the CPU speed on the set up screen.
