On/Off switch:
Turn the computer on by quickly depressing
the yellow on/off button on the upper right-
hand side of the computer (approximately ½ to
1 second). After the computer boots up, by
pressing the on/off switch again, the unit will
automatically follow proper Windows shutdown
procedures.
Pressing the on/off button twice in rapid
succession replicates CTRL ALT DEL
keystrokes. Holding the on/off button down for
a longer period of time (4-5 seconds) causes
an emergency forced shut down of the
computer.
When the HAMMERHEAD is operating, the
side switch will function according to the
selection on the “Advanced” tab of the Power Options. To see
the current setting, go to Start, Control Panel, Performance and
Maintenance, Power Options and click on the Advanced tab.
USB connector:
The Universal Serial Bus is a hot swappable, daisy chainable
serial port. It can be used for devices like keyboards, mice,
floppy drives, CD-ROM or DVD drives, cameras, modems,
scanners, etc. Devices can be connected to the
HAMMERHEAD XRT with the computer turned on, without
requiring a reboot. There is a limit of 128 concurrent devices
per USB port. The HAMMERHEAD XRT can supply up to .5
amps of current through the USB port. External USB hubs are
available that will supply power to external devices without
using the HAMMERHEAD XRT’s power supply.

Tips for proper use and care of your computer
The HAMMERHEAD XRT is a rugged field computer, but it is an
electronic device and reasonable precautions should be taken:
•
Don’t subject the computer to extreme heat by placing it on the
dashboard of a vehicle with the display facing the sun.
•
Don’t leave the computer in temperatures below -25
°
F.
•
Don’t pile tools or heavy objects on top of the computer.
•
Avoid severe impacts, especially on the display glass.
•
Don’t place the unit on the hood or roof of any vehicle, as it
might be left behind.
•
Don’t try to take the computer apart. Special tools are required
to disassemble the computer.
•
Don’t use excessive force when inserting PCMCIA cards in the
PCMCIA slots, as they may break.
