4. On the Power Parameters screen, use the up or down arrow keys to toggle
the Advanced Power management selection screen to Yes then press the Yes
key.

5% above the Low Power warning onset. Press the Yes key to accept the
changes, then press the Esc key to return to the DOS prompt. The Low
Power alarm should no longer be sounding.
Recovering From a FS/2 Lockup
The FS/2 may lock up during field operations (seen infrequently during intense
system testing). To clear the locked condition, reboot the FS/2. The conventional
means of rebooting a DOS computer, pressing Ctrl-Alt-Del, works on the FS/2, but
only at the DOS prompt. If the FAMlog program is running, a program breakout or
hardware reset will have to be performed. The program breakout should be attempted
first, since the hardware reset may result in a total loss of the FS/2 memory contents.
Program Breakout
1. Turn the FS/2 off. If the power key does not respond, remove and replace the
battery cap to power off the FS/2.
2. Press the X and P keys simultaneously.
3. Press and release the power key while still holding the X and P keys down.
4. Release the X and P keys. The FS/2 boot screen should appear.
5. Press any key to reboot the FS/2, then restart FAMlog.
Hardware Reset
1. With the FS/2 off or on, press and hold down both shift keys and the Power
key.
2. Continue to hold all three keys down until the screen contrast turns to black.
3. Release the keys. The FS/2 boot screen should appear.
4. Press any key to reboot the FS/2, then restart FAMlog.
