Tips for proper use and care of your computer
The Hammerhead 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 store the computer in temperatures below -40°C.
•Don’t pile tools or heavy objects on top of the computer.
•Avoid severe impacts, especially on the display glass.
•Don’t try to take the computer apart. Special tools are required to
disassemble the computer. Disassembly of the unit by
unauthorized personnel may void the warranty.
•Don’t use excessive force when inserting PC Cards into the
CardBus slots, as they are keyed to go in only one way.

2Hardware Operation
Turning on the unit
Turn the computer on by quickly depressing the yellow on/off button on
the upper right-hand side of the computer (press for 1-2 seconds).
Note: Holding the on/off button down for a longer period of
time (5+ seconds) causes an emergency forced shut down
of the computer.
The Hammerhead will perform self-checking routines during the start-up
process. All units are configured at the factory to automatically boot to
the Microsoft Windows Desktop unless a custom configuration has been
requested.
Pen operations
(For Pen Based Computers only. If you have a Computer with
Touch Screen, see page 14 for Touch Operations)
The pen is the primary screen navigation and data entry tool for the
Hammerhead. Without a keyboard attached, the pen is the only
means of communicating with the computer. Do not lose or
misplace the pen. The pen is usually tethered to the unit or its carrying
case. All users are encouraged to purchase a spare pen as a backup.
The pen functions like a two-button mouse. There are two switches in
the pen, one in the pen tip and another on the barrel of the pen. The tip
switch performs the same functions as the left button on a mouse and
the barrel switch performs like the right mouse button. Very few
Chapter
Chapter 2 – Hardware Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 13
applications require the use of the pen’s barrel button. Do not depress
the barrel switch when writing on the display; it will adversely affect
handwriting recognition.
To activate the tip switch, simply press the tip of the pen against the
display. This is similar to clicking the left button of a mouse. Double
clicking is accomplished by double tapping with the pen. Move an icon
by pressing the pen directly overhead and dragging the icon to the
desired destination, keeping the pen in constant contact with the display.
For right click functions, just depress the switch on the side of the pen. In
addition, XP Tablet PC Edition allows right click via pressing and holding
the stylus on the screen for 1+ seconds. Press and hold is an optional
feature. You can turn the feature on or off by going to Control Panel, and
then Tablet and Pen Settings.
Tapping the pen requires only light to moderate pressure. It is possible
to damage the pen by pounding the tip against the display with force.
Most problems using the pen are related to tapping speed and the
tapping area size. When using XP Tablet PC Edition, attributes related
to use of the pen (e.g. tap speed) can be adjusted by clicking on Control
Panel, Tablet and Pen Settings, and then the Pen Options tab. You can
also improve handwriting recognition accuracy by indicating if you are
right or left handed on the Settings tab. For Windows XP Pro operating
systems, look in the PenOffice tools folder found in the Windows
Program list.
The Hammerhead utilizes a proximity-sensing electromagnetic digitizer.
This component tells the computer the pen’s exact position. The
computer senses the pen as it nears the display and the cursor appears
when the pen is approximately an inch away. This allows visibility of the
exact location of input before making actual contact with the display.
The location of the cursor on the display is the location of input
regardless of the location of the pen tip. The cursor and the pen tip
should be closely aligned when the pen is in contact with the display. If
the pen and the cursor are out of alignment, click on Control Panel,
Tablet and Pen Settings and go to the Settings tab where you can
calibrate the screen for both landscape and portrait orientations. If you
are using Windows XP Pro, follow the instructions provided in the
PenOffice tools folder found in the Windows Program list. Confirm the
display is on the appropriate setting before attempting to realign the pen.

DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 14
Touch Operations
(For Touch computer models only. See page 12 if you have a Pen
based computer.)
Touch Screen Operation
The touch screen replaces a mouse in normal Windows operation.
Wherever you touch the screen with your finger or stylus, the computer
interprets it as a mouse click. Due to the nature of the touch screen, it is
sometimes hard to drag objects across the screen and it is also hard to
move the pointer around the screen without selecting the object below
the cursor. It is also difficult to capture a signature on touch screen units.
This should be taken into account when applications are being
developed for touch screen devices.
Caring for the Touch Screen
With minimal maintenance, the touch screen will last many years. When
operating the touch screen, you should not use an abrasive or metallic
pointer. The touch screen is easily scratched if an abrasive stylus is
used. We recommend using your finger or a plastic tipped stylus. Be
careful not to let sand or grit sit on the screen. Cleaning of the touch
screen can be done with a regular plastic cleaner such as Plexus.
Chapter 2 – Hardware Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 15
Battery use and care
The Lithium Ion batteries used in your Hammerhead computer offer the
best technology available today. These 'Smart Batteries' provide
Hammerhead users with the greatest power density and the most
accurate gas-gauge possible. To achieve the best possible performance
from your batteries, we recommend using and maintaining the batteries
in accordance with the instructions provided below.
Getting started with your new batteries
Your unit comes with a Lithium Ion battery that is shipped (uninstalled) in
the box with the unit. The unit may also have a non-working battery shell
in the second battery slot that shows you how the battery is to be
installed. Due to current regulations regarding shipment of Lithium Ion
batteries, your battery(s) will arrive in a partially charged condition,
typically with a maximum charge of 30% to 50%. You need to install
your battery before turning on the unit. We also recommend that you
fully charge your batteries before using them. If you do not plan to
deploy your computer immediately, please be aware that the batteries
self-discharge at a slow rate, typically less than 10% per month at
normal temperatures.
How to install new batteries
The Hammerhead has the capability
to run on one or two batteries in the
field. The unit does not require both
batteries to run. The two-battery
design allows users to hot swap
batteries without turning the
computer off.
To install or replace a new battery,
locate the round knob in the battery compartment on the back of the unit.
The knob holds the batteries in place and is designed so the batteries
cannot be taken out at the same time. Simply turn the knob until the
quarter piece exposes the corner of the battery that is to be replaced. A
lip on the battery aids easy removal. Install the new battery by placing it
into the compartment and turning the knob to cover the edges of both
batteries.

When to recharge batteries
The green LEDs on the upper right front of the unit indicate the power
status of the battery. At full charge, all five LED indicators will light a
solid green. Each LED represents approximately 20% of the total charge.
As the battery power availability decreases, the LED’s will turn off from
top to bottom. For example, when the top light begins to flash, the
computer has approximately 90% charge remaining. If four LED’s are lit
a solid green, an estimated 80% of the total battery charge remains. If
three are lit a solid green and the fourth one begins flashing, the
computer has approximately 70% charge remaining.
The last LED indicator will begin to flash when approximately 10% of
battery power remains. When the remaining battery power becomes
critical, all data should be saved. Failure to do so may result in lost data!
Replace one of the batteries with a fresh battery or recharge the unit.
When the Hammerhead is turned off, the battery status indicators will
also turn off after a delay of a few seconds. When the unit is placed in
standby mode, the battery status indicators will flash as a reminder the
unit is on standby.
How to recharge your batteries
The Hammerhead’s batteries automatically fast charge
any time the Hammerhead is connected to an external
power source (AC or DC). This is accomplished using
either the Hammerhead internal battery charger or an
approved DRS power source/battery charger.
To recharge the battery using the AC adapter, plug the
circular connector of the AC adapter into the AC
connector in the Hammerhead or in the power supply
port on the replicator. Charging begins automatically
as the unit is docked when using a vehicle-docking
mount, desktop docking station or a wall mount docking
station. The Hammerhead is fully functional as it
charges. Using the unit as it charges will only slightly
lengthen the recharging process. Don’t be alarmed if
batteries feel warm to the touch during this process. It
is normal for a battery to become warm during charging
and discharging. AC adapter
plugs in here
Chapter 2 – Hardware Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 17
Do not use any external power source other than the AC or DC adapters
provided with the Hammerhead. The power supply “brick” for the
Hammerhead specifies 15V. DO NOT plug the external power supply
from the Battery Charger into the computer or docking mechanism.
This power supply is 24V and will cause permanent damage to the
computer. Also, do not connect the computer to more than one
power source at a time, such as an AC power supply and docking
station, when charging the unit or permanent damage to the battery
or computer may occur.
How to tell when batteries have finished charging
When charging, the green charge indicator light will flash while the unit is
recharging. When charging two batteries, the secondary battery (see
diagram below) will charge to 80% of full charge, then the primary battery
will charge to 80%. After both batteries reach 80%, the secondary battery
will then charge the remaining 20%, after which the primary battery will
complete its recharging process. This method provides the best ratio of
charge time to run time for short battery charge cycles. When batteries
are fully charged, the charge indicator light will stop flashing and remain
lit.
How to increase battery "run time”
The total run-time of the battery is dependent on a variety of factors
including temperature, backlight requirements and computer usage.
To ensure maximum performance of the battery, optimize your
computer’s power management features. Settings for the display and
the hard drive shutdown, as well as the use of stand-by and hibernate
mode, result in lower overall drain on the battery, effectively increasing
the computer’s operating time.
When to replace your battery
Battery life is dependent on battery usage. Every time a battery is fully
charged and discharged, it decreases the amount of energy stored in the
battery.
To determine if the battery is past its prime, first check the Silver
warranty label on the bottom of your battery. Batteries beyond one year

Chapter 2 – Hardware Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 18
of service may experience shorter run times. Recommended
replacement for batteries is once a year or every 400-500
charge/discharge cycles for optimal battery performance.
Where to purchase replacement batteries
The Hammerhead uses long lasting Lithium Ion batteries that are custom
made for DRS Tactical Systems, Inc. If you need to purchase
replacement batteries for your Hammerhead computer, contact your
sales representative. Do not substitute any other batteries. Substituting
batteries may result in a void warranty.
How to store batteries when they’re not in use
The following storage tips will help you optimize the capacity and
performance of your batteries.
•If the battery will not be in use for a month or longer, it is
recommended that it is removed from the computer for storage.
•Store batteries in a cool, dry place.
•Do not leave batteries in direct sunlight during the summer
months or any other unusually hot location.
•Do not expose battery terminals to metal objects or moisture,
which may short-circuit your battery.
•For long-term storage, store batteries below 50% state of charge
because the deterioration of battery capacity is slower at lower
state of charge. However, do not store batteries in a fully
discharged state.
Safety and handling considerations for your batteries
To make the batteries as safe as possible, DRS Tactical Systems, Inc.,
along with our approved vendors, has incorporated several built in safety
features to protect the pack. The safety circuit in your battery cannot
protect against handling abuse. Please use the following safety rules
when handling and using Lithium Ion batteries.
•Do not expose the batteries to extremely high temperatures. Do
not dispose of batteries in fire.
•Do not short circuit the battery or reverse polarity. Avoid placing
batteries around metal objects such as keys, pocket change,
paper clips and jewelry.
Chapter 2 – Hardware Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 19
•Do not let children play with batteries.
•Do not crush, dent or allow any deformation of the battery.
•Do not disassemble or open the batteries or try to alter or bypass
the safety circuit.
•Do not allow the battery to get wet.
•Avoid exposing the battery to extremely humid environments.
•Avoid exposing the batteries to electrostatic discharge.
•Avoid extreme shock and vibration to the battery. Avoid dropping
the battery.
•Do not use or connect the battery to any other devices.
•Do not allow batteries to remain discharged for long periods of
time.
Disposing of your batteries
The batteries used in the Hammerhead are not considered hazardous
waste by EPA regulations; however local regulations may require
specific methods of disposal. We strongly encourage recycling and will
be happy to recycle batteries for you. Please contact your local sales
representative or our technical support department for assistance.
Battery tips for the best performance
•Fully discharge your battery before recharging. By charging the
battery only when it has become completely discharged, you will
reduce the number of charge cycles and thus extend the life of
your battery.
•Fully charge within 24 hours of discharge. Batteries stored in a
fully discharged state may be subject to faster deterioration.
•Battery charging should be done at temperatures between 0°C
to 45°C, preferably room temperature. The battery could
deteriorate more quickly when charged at high temperatures.
•Discharging should be done at temperatures between –10°C to
+60°C, preferably room temperature.
•Store your battery in a cool dry place, preferably at temperatures
between 20°C to +60°C. Your battery may deteriorate more
quickly if stored in high temperatures such as a vehicle in the hot
sun.

DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 20
Calibrating Batteries
When used under normal operating conditions, where the battery goes
through a cycle of being charged, fully discharged and recharged again,
you should not have to calibrate your Hammerhead batteries.
Periodically, however, batteries may require calibration to improve
accuracy of the battery gauge, particularly if they go through continual
cycles of shallow discharges without ever achieving a fully discharged
state. To ensure that the batteries are operating accurately and at their
best performance levels, we offer a Smart battery charger that will
perform the calibration procedure for you. (DRS Model Number 9800-
17019-0000)
This Smart battery charger is based on Intel’s System Management Bus
(SMBus) interface for Advanced Configuration and Power Interface
(ACPI). In addition to calibration, the charger can fully charge two
batteries in less time, compared to the current Hammerhead external
battery charger. Typical Charge Time per battery is 1.7 hours.
Note: Only calibrate batteries when they need it. Calibrating a battery
unnecessarily will increase the cycle count and thereby reduce the
battery life.

Removable hard drive
The hard drive compartment allows field upgrades or repairs without
opening the Hammerhead. Some customers may have IT Departments
that will be trained to replace hard drives at the customer location. You
should not open the hard drive compartment without the proper
training from DRS Tactical Systems, Inc. Please contact our technical
support department at 888-872-1100 before removing the cover plate of
the hard drive compartment. Any tampering of the hard drive will result in
a void warranty.
Connectivity
Most often, connectivity with the Hammerhead is via the docking
connector on the backside of the unit. Most customers also purchase a
port replicator, desk dock, or Hammerdock vehicle dock that provides
standard ports for communications, keyboard, and power supply. Port
replicators and docking stations may be customized to your
requirements and may not be configured exactly as described below.
Port replicators
There are several variations of port replicators (flat, angled, custom, etc.)
New connectivity options are constantly in development. The following
features are available on the standard port replicator.

DB-9 serial connector, although only a subset of
standard signals are supported.
Thumb Thumbscrews secure a positive connection.
screws: Insert the port replicator fully before engaging
thumbscrews. Be careful not to over tighten
thumbscrews.
The standard port replicator also doubles as a desktop stand for the
Hammerhead. Simply press the male docking connector on the port
replicator into the female docking connector on the back of the unit. The
connectors are correctly oriented and only fit in one direction. It is
impossible to join them incorrectly. Make sure the connector is fully
inserted confirming the port replicator fits snuggly against the back of the
computer. Turn the thumbscrews in a clockwise direction to ensure a
reliable, positive connection. Do not over tighten.
External power should be connected to the port replicators after
being firmly connected to the Hammerhead. Do not connect the
port replicator to the computer while power is attached to the port
replicator.
Flat port replicators and custom cable sets are available when
connectivity is needed while the unit is mobile. Some custom
configurations provide access to ports in the computer housing.

Desktop docking station
The Desktop Docking Station
(DESKDOCK) provides complete
connectivity and integrated options (e.g.
LAN adapter, fax/modem, etc.) for using
the Hammerhead on a desktop.
At a minimum, the DESKDOCK offers the
following connectors for the connection of
external devices:
•Two RS-232 serial ports (COM1 and COM2 – 3-wire serial)
•One Centronics-compatible parallel port/floppy interface
•One keyboard port
•Power connector
•One USB port
•One SVGA video port
If the Hammerhead is equipped with video output capabilities, one COM
port can be used as a VGA port. If a DESKDOCK is equipped for
communication with a network, the connection is made through the USB
port.

Vehicle docking
The HAMMERDOCK offers compact versatile mounting for a variety of
automobiles. The one-piece aluminum body ensures sturdy docking with
no adjustments. The HAMMERDOCK has tilt swivel functionality, a built-
in keyboard tray, and a push button key lock. A breakout box with a 3-
foot or 6-foot cable provides convenient installation for permanent
connections.
SIDE VIEW FRONT VIEW
Noise reduction circuitry, surge protection, reverse polarity protection,
and power conditioning circuitry are built into the HAMMERDOCK. In
some cases a GPS receiver may also be included. Connectivity on the
rear of the HAMMERDOCK includes a power connector, keyboard
connector, and USB connector. Connectors in the “break out box” at the
end of a 3’ or 6’ cable include 1 keyboard, 2 COM ports, 1 USB and 1
parallel port.
No adjustments are ever required to assure precision insertions of the
docking connector. The tension of the tilt/swivel functions and the angle
of the keyboard tray are the only adjustments available on the
HAMMERDOCK. All tension adjustments are made at the time of
installation with an Allen key provided with each docking system. The
keyboard tray is removable.
The computer can be secured in position by turning down the spring-
loaded red retention latch. Once the latch is turned completely down,
the push button lock can be depressed to prevent unauthorized removal.

Heater option
The Hammerhead supports an optional heater package that improves
boot time in colder environments and allows the computer to operate at
temperatures down to -20oC. You can enable the heaters to
automatically activate while your machine is booting and/or while it is
running. If enabled, the heaters will automatically activate each time the
ambient temperature falls below a predetermined level.
CardBus/PCMCIA cards
The Type III slot in the Hammerhead will support both CardBus and/or
PCMCIA cards. CardBus and PC Cards are two alternative types of
PCMCIA interfaces (or slots) on laptops, desktops, and PDAs. PCMCIA
cards are based on a 16-bit interface, while CardBus is a 32-bit interface.
This allows the CardBus Card to transfer data at speeds exceeding 100
Mbps, while a 16-bit PCMCIA card transfers data at approximately 20
Mbps. CardBus also offers lower power consumption: CardBus Cards
are all 3.3-volt cards, while 16-bit PCMCIA Cards can be 5-volt or 3.3-
volt.
To insert a card, take off the door by removing the two screws that
secure the door. Cards should be inserted face up (i.e. the up arrow on
the card should point toward the front of the Hammerhead). Do not
apply excessive pressure when loading cards. They are keyed and
should slide in easily. Remove the card in the same manner.
Most PCMCIA devices are too fragile for direct connections in field
environments. In response, DRS provides a variety of doors that extend
beyond the housing to contain a combination of connectors and cable
assemblies needed to connect to common PCMCIA devices. These
extended doors serve two purposes: 1) they provide for a sturdy and
highly reliable connection not possible when connecting directly to a
PCMCIA device, and 2) they maintain the environmental integrity of the
Hammerhead by fully sealing the PCMCIA compartment while providing
the needed connectivity. Extended doors are available only for those
PCMCIA devices that have been tested and recommended by DRS.
Custom doors may be available for large purchases.

Internal “Flex Space” for OEM modules
In addition to a Type III CardBus/PCMCIA slot, the Hammerhead
computer has an internal “Flex Space” that will accommodate optional
radios such as GPS and GPRS. The antenna for the internal module is
mounted on the top right hand side of the computer and does not
interfere with the CardBus/PCMCIA door and antenna options, which are
located on the upper left hand side of the computer.
ProtectIT™ (this feature not yet shipping)
We have spent a considerable amount of time designing and
implementing shock-absorbing fixtures to protect the data on the hard
drive from damage in the likely event of an accidental fall. The
Hammerhead debuts an exciting new feature called ProtectIT™.
ProtectIT™ (a combination of hardware and software) can sense a
sudden increase in acceleration that may occur from the unit being
dropped from a standing position, or falling off the hood of a truck. When
a fall is sensed, the hard drive read/write heads are instantaneously
retracted preventing them from impacting the hard drive spindle
surfaces, preventing what is commonly referred to as a “head crash”.
Think of ProtectIT™ as a “Seat-belt” for your data.
The ProtectIT™ application is incorporated in the HH Utility, which is
preloaded on the Hammerhead. Simply click on the utility and select the
ProtectIT™ tab. With the HH utility running, you will notice the arrow will
change direction according to the movement of your Hammerhead
Tablet PC. The hard drive read/write heads are retracted or “parked”
when the color of the arrow changes from Green to Yellow. The
interface allows the user to enable, disable or control the sensitivity of
ProtectIT™.

Using power schemes
Power schemes are a collection of settings that manages the power
usage of your computer. You can select from a number of power
schemes that are available in Power Options in the Control Panel, you
can adjust individual settings of any available power scheme, or you can
create your own power schemes to suit your particular system and
preferences.
Standby
Standby is a low-power state in which your LCD and CPU turn off. When
you want to use the computer again, it comes out of standby quickly and
your desktop is restored exactly as you left it. Use standby to save power
when you will be away from the computer for a short time while working.
Hibernation
Hibernation is a state in which your computer shuts down to save power
but first saves everything in memory on your hard disk. When you restart

functionality to your computer. To launch the Hammerhead Utilities
program, click on the icon found in the quick launch bar.
If the icon is not found, you can launch the program by clicking on
START, ALL PROGRAMS HH UTILITIES.
Adjusting screen brightness
The brightness of your Tablet PC screen is often the number one
consumer of power, so you can conserve battery power by turning down
the screen brightness on your Hammerhead. For optimal battery
function we recommend that your computer is set for “Auto Off” in bright
light, “Auto Dim” in low light and the advanced backlight settings are
loaded with default settings. This configuration is designed to give you
an optimal balance between performance and battery life. For computers
with Transmissive (indoor viewable) displays, it is highly recommended
that you do not use the “Auto Off” backlight settings.
Manual brightness adjustment
The brightness slider control allows you to manually adjust the backlight
brightness. Click on the bar and slide it to the left or right to achieve the
desired brightness. When using the All-Vis LCD, DRS recommends not
to select any of the Auto Back Light Settings and to slide the Brightness

QuickBack™
QuickBack™ is a new backup and restore feature on your Hammerhead
computer that allows you to make an exact copy of your hard disk's
contents on a hidden partition of your computer, which you can use to
restore your PC if the main image ever becomes corrupted or unusable.
Hammerhead Rugged Tablets implement the QuickBack™ functionality
using the Acronis True Image OEM software package. The True Image
application provides a number of useful System Backup features
including the creation and storage of an Archival Backup Image, the
ability to store up to two additional User created Backup Images, and the
ability to create an Emergency Bootable CD for System Recovery.
The System Hard Drive is divided into several sections or “Partitions”.
•The C partition is the primary partition that contains the Windows
files, Application Program files, User files, etc and the C Partition
is used as the primary system boot drive for normal operations.
•The D partition contains low level tools for firmware upgrades
and the User Backup Images of the C Partition. The firmware
tools in the D partition are accessed by a system boot to the
Internal EFI shell (Intel Extensible Firmware Interface). Ideally
the D partition is made large enough to contain the Firmware
Tools and download files and at least two compressed User-
generated backup images.
•The DRS-Acronis SVC Partition is a “hidden” partition that is
used to store the Original Archive Backup Image. This partition
is sized by the True Image tool and is made to be just large
enough to contain the compressed Archive Backup Image.
The compressed image of a partition can only be stored in one of the
other partitions for backup purposes. This allows the User to overcome
the most common image corruption issues and to restore the system
back to the last saved image. Note that if the entire hard drive becomes
Chapter 3 – Software Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 35
defective of if the hard drive fails then the QuickBack™ feature will not
be able to restore the system. Even the System Recovery CD looks for
the backup image on the hard drive. The periodic use of an alternate
backup tool is recommended to provide backup images on external
media in case of catastrophic hard drive failures. You may decide to
purchase the upgraded full-featured Acronis True Image tool to be able
to backup and recover an image from an external drive.
Archive Backup Image
The original Archive Image is created and supplied by DRS as part of the
system manufacturing process. The Archive Backup Image contains the
original C and D partition images and is stored in a compressed form in a
hidden partition on the system hard disk. This hidden partition is not
visible or accessible to the user with the standard system file access
toolset. The Archive Backup Image can be used to restore the hard
drive by selecting the F11 option when prompted during the system boot
to immediately start the standalone True Image Application. Within the
True Image application, the User can select the “Restore Original
System Installation” button and follow the on-screen directions to restore
the entire Archive Backup Image onto the C and D partitions of the
System Hard Drive. Note that any changes or additions to either of
these two partitions will be lost. This includes User Backup Images that
have been placed in the D partition area.
User Backup Image(s)
The User can create up to two User Backup Images of the C partition
(Compressed Images of C can be stored up to the available space in the
D partition). The User Backup Images are typically created as desired
by the User using the True Image application under Windows. The User
Backup Images are stored into the D partition of the system hard drive.
Currently, the existing Image size and the D partition size allows up to
two User Backup Images to be saved at one time. If the user increases
the size of the image significantly with the addition of new software, then
only one backup image can be stored. With the addition of very large
amounts of user data it is possible to grow the image large enough that it
can not be compressed into the available space on the D partition (In this
case the True Image will inform the user that no backup into the
requested location is possible).

Chapter 3 – Software Operation
DRS Tactical Systems, Inc.
Hammerhead User’s Guide –V062906 36
Emergency Bootable CD
The user can create an Emergency Bootable CD using the True Image
Application under Windows and an attached CD/DVD disk drive with
write capability. If the C drive becomes corrupted and the system fails to
boot normally, then the Emergency Bootable CD provides the user with
the ability to boot the system to the True Image Application. The User
can then restore the C partition from one of the User created Backup
Images.
To boot from the Recovery CD:
•Place the recovery CD in a CD drive attached to the System
•Boot the system and press the ESC key when the DRS splash
screen appears
•Select Boot Manager
•Select the CD drive (the exact text depends on the type of drive
being used)
As well as reading an image you've already made, the rescue disc can
actually make a brand new image — handy if you want to copy a data
partition on a PC that's no longer bootable.
How to Access QuickBack™ for Initial Set-Up and Help Features
The QuickBack™ feature can be accessed by clicking on the Acronis
True Image shortcut on the computer’s desktop. You can also access it
by clicking on START > All Programs > Acronis > True Image. The
program includes an extremely easy to use wizard interface and detailed
HELP features.

Windows XP Tablet PC Edition Features
This section describes some of the unique features and benefits of
Microsoft’s XP Tablet PC Edition software for your Hammerhead Tablet.
(Note: This section is not applicable for units with XP Pro Operating Systems.)
Tablet and pen settings
Windows XP Tablet PC Edition 2005 lets you customize the tablet and
the tablet pen to suit the way you work. Not all users have to use the
same Tablet and Pen Settings. Individual users can save their own
settings. Attributes related to use of the pen can be adjusted by clicking
on Control Panel, Tablet and Pen Settings.
In this section you can:
•Change the screen orientation between landscape and portrait modes.
•Set the pen for left- or right-hand use.
•Change the default settings of the hardware buttons on Tablet PC.
•Change how a pen matches mouse movements, such as single-click,
double-click, right–click, and hover.
•Set handwriting-recognition language.
•You can also customize features of Microsoft Windows Journal, Input
Panel, and Sticky Notes to get the most from your Tablet PC.
Screen rotation – this section will be replaced with new instructions
XP Tablet PC supports rapid display rotation between portrait and
landscape modes without requiring the user to restart the computer. That
makes it easy for users to work in either mode according to their
preferences. For example, when annotating PowerPoint slides, it may be
preferable to work in landscape mode—the same orientation as most
PowerPoint slides. However, when taking notes in Windows Journal, it is
more natural to do so in portrait mode—just like taking notes in a paper
notebook. The Tablet PC screen displays rotate almost instantly, so the
user can go back and forth as often as desired or needed for a specific
task.

Handwriting using the Input Panel
One way to write with the digital pen when you're not using your
keyboard and mouse is by going to the Input Panel. The Input Panel has
three views, the writing pad, character pad and the on-screen keyboard.
You can input text into applications using your own handwriting on the
writing pad and/or character pad or tap in characters using your pen with
the on-screen keyboard. The Tablet PC Input Panel is hidden when you
first start, but is easily opened.
How to open the Input Panel
To open Input Panel next to the location where you want to enter text,
tap the floating Tablet PC Input Panel icon. The icon appears
automatically when you rest the pen near the field that you want to
complete, such as the "To" field in a new Microsoft Outlook e-mail
message, or when you tap the location on the screen where you want to
insert text, for example, in the middle of a paragraph in a Microsoft Office
Word 2003 document.

You can move Input Panel anywhere on the screen by using the move
handle, which appears at the far right side of Input Panel. Or, you can
dock Input Panel—that is, set it to appear at the top or bottom of the
screen. When docked, Input Panel is always available and does not
cover any open windows.
Input Panel offers three entry modes—the writing pad, the character pad,
and the on-screen keyboard.
