Tips for proper use and care of your computer
The HAMMERHEAD RT 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 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 ½ to 1 second).
Note: Holding the on/off button down for a longer period of
time (4-5 seconds) causes an emergency forced shut down
of the computer.
The HAMMERHEAD RT 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
The pen is the primary screen navigation and data entry tool for the
HAMMERHEAD RT. 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. Attaching the tether to one of the zippers on the carrying case with
a split ring allows the tether to be anchored on either side of the
computer. By shifting the position of the zipper, the tethered pen is
convenient for right or left-handed users. 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
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 14
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.
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 98/2000/XP Pro
operating systems, look in the PenOffice tools folder found in the
Windows Program list.
The HAMMERHEAD RT 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 98/2000/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.

Chapter 2 – Hardware Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 15
Touch Operations
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. This should be taken into account when applications are
being developed for touch screen devices.
The touch screen unit comes standard with Windows XP Pro, Pen Office
Calligrapher and My-T-Pen on screen keyboard software and therefore
may not offer some of the Tablet PC functionality of a pen unit running
XP Tablet PC Edition such as screen rotation. It is also very difficult to
capture a signature on touch screen units.
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
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 16
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 RT 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, turn the round knob 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 for 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.

Chapter 2 – Hardware Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 17
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 RT 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 Walkabout 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.
Do not use any external power source other than the AC or DC adapters
provided with the HAMMERHEAD RT. Also, do not connect 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.
Chapter 2 – Hardware Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 18
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 suspend, 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 date
code on your battery.
Batter
y
knob

Chapter 2 – Hardware Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 19
Batteries beyond one year of service may experience shorter run times.
WalkAbout recommends replacing your batteries 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 WalkAbout Computers. If you need to purchase replacement
batteries for your Hammerhead computer, contact your WalkAbout 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, Walkabout Computers, 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
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 20
• 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 WalkAbout’s Hammerhead Computers are not
considered hazardous waste by EPA regulations; however local
regulations may require specific methods of disposal. We strongly
encourage recycling. WalkAbout will be happy to recycle batteries for
you. Please contact your area representative.
Battery tips for the best performance
• Fully discharge your battery before recharging.
• Fully charge within 24 hours of discharge.
• Battery charging should be done at temperatures between 0°C
to 45°C, preferably room temperature.
• Discharging should be done at temperatures between –10°C to
+60°C, preferably room temperature.
• Store your battery at temperatures between 20°C to +60°C. Do
not store batteries in a fully discharged state.
Calibrating Batteries
Periodically, batteries require calibration to improve accuracy of the
battery gauge. 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. (WalkAbout Model Number
900125-001)
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

Chapter 2 – Hardware Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 21
batteries in less time, compared to the current WalkAbout external
battery charger. Typical Charge Time per battery is 1.7 hours.
When should I calibrate my batteries?
You should calibrate your batteries if the HH Control Panel on your unit
indicates a max error of greater than 2%. To check the max error of the
battery, go to START, PROGRAMS, HHUTILITIES, HH Control Panel.
Click the Information Button, then click the BATTERIES button. On the
upper right, select the battery radio button of the battery you wish to look
at. The “Max Error” is shown on this screen.
Note: Only calibrate batteries when they need it. Calibrating a battery
unnecessarily will increase the cycle count and thereby reduce the
battery life.
What are the Over Temperature and Over Voltage boxes in the HH
Control Panel?
To insure the safety of the Hammerhead Computer at all times, the HH
Control program monitors battery temperature and voltage. If a
malfunction ever causes either of these values become too high, the
computer will shut down to prevent any permanent damage to the
computer.
Removable hard drive
The hard drive compartment allows field upgrades or repairs without

Connectivity
Most often connectivity with the HAMMERHEAD RT is via the docking
connector on the backside of the unit. Most customers also purchase a
port replicator, DESKDOCK, 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.
Male docking The male docking connector is inserted into the
connector: female docking connector on the back of the
computer to activate all ports in the port
replicator.
External External power connector. Use only the
power: power supplies provided especially for the
HAMMERHEAD RT, which supply the required
DC power from a standard AC outlet.

The standard port replicator also doubles as a desktop stand for the
HAMMERHEAD RT. 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. Do not connect the
port replicator to the computer while power is attached to the port
replicator. Attach the port replicator and then attach the power to the
port replicator.
Flat port replicators and custom cable sets are available when
connectivity is needed while the unit is mobile. External power should be
connected to the port replicators after being firmly connected to the
HAMMERHEAD RT. 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 RT on a desktop.
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 RT 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.
Security keys for fleet users are identical to eliminate logistic problems.
The HAMMERDOCK cannot be installed without a base to mount it in the
vehicle. Contact WalkAbout for a current list of vehicle mount providers.
Heater option
The HAMMERHEAD RT supports an optional heater package that
greatly improves display readability in colder environments and a hard
drive heater that prevents drive freezing. You can enable the heaters to
automatically activate while your machine is running, booting or even
while it is turned off. If enabled, the heaters will automatically activate
each time the ambient temperature falls below a predetermined level.

CardBus/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.
The Type III slot in the Hammerhead RT will support both CardBus
and/or PCMCIA cards. 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 RT). 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, WalkAbout 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 RT 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
WalkAbout. 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 RT933
computer has an internal “Flex Space” that will accommodate optional GPS,
GSM and Bluetooth modules. 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 is located on the upper left
hand side of the computer.

available while you are working away from your desk.
To check your battery power, double-tap the Power Meter icon in the
Windows system tray. The Power Meter icon appears as a battery when
your Tablet PC is running on battery power. The icon changes to a plug
when on AC power. You can monitor your battery as it charges to see
when it is fully charged.
Setting the battery alarm
You can set a warning alarm that is activated when your battery falls
below the levels you have defined as low and critical. You can change
the battery level at which the alarm or message is activated.
• On the taskbar, tap the Start button, and then tap Control Panel.
• Tap the Power Options icon.
• Tap the Alarms tab.
• Under Low battery alarm and Critical battery alarm, specify the
settings that you want by moving the slider.
• Tap Alarm Action to select the type of alarm notification and
resulting action you want. In the critical battery alarm section, under
Alarm Action, WalkAbout recommends a Shutdown or Hibernation
setting, not a Standby setting.
Turning off power-consuming peripherals
Peripheral devices on your computer use power. For instance, your
Tablet PC may have a wireless network connection, a modem card or
USB devices. Because some of these peripherals can draw a significant
amount of power, you should consider unplugging them or turning them
off in situations where you want to conserve battery power. For
information on turning off your wireless network connection, please refer
to the manufacturer's documentation.

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
the computer, your desktop is restored exactly as you left it. Use
hibernation to save power when you will be away from the computer for
an extended time.

Adjusting Screen Brightness and Backlight Settings
The Hammerhead RT comes with a Utility program that provides
additional 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 RT. 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, WalkAbout
recommends not to select any of the Auto Back Light Settings and to
slide the Brightness slider all the way to the right.

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 XRT
Pen Tablet.
(Note: This section is not applicable for units with XP Pro, Windows 2000 or
Windows 98 Operating Systems. Most computers with these operating systems
come standard with Pen Office Calligrapher handwriting software and My-T-Pen
onscreen keyboard.)
Tablet and pen settings
Windows XP Tablet PC Edition 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
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
Click the Input Panel button on the task bar. The Tablet PC Input Panel
opens. To hide the Input Panel, click the Input Panel button again. To
open Input Panel next to the location where you want to enter text, tap
Chapter 3 – Software Operation
WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 36
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.

WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 37
Writing Pad
You can enter text by using ink in the writing pad. The writing pad is
especially useful for tasks such as adding text to a Word 2003 document
or updating a Microsoft Office Excel 2003 spreadsheet. As you write,
Input Panel expands to accommodate more text as needed. If you want
to convert ink to text, Input Panel does so dynamically.
Character Pad
The character pad also converts your ink to text so that it can be inserted
into a program, but you use it to enter one letter at a time. The character
pad is particularly useful when you need the highest levels of accuracy—
for example, when you're entering an e mail address or a URL. The
characters that you enter into the character pad are immediately
converted to text, so you can spot and fix any errors immediately.

WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 38
On-screen Keyboard
Use the on-screen keyboard when you don't want to use ink but you do
want to use the pen, or when you're using a Tablet PC without an
attached keyboard. Simply tap the letters on the keyboard to form words.
Input Panel enters the text directly in the field or at the insertion point of
the active program. The on-screen keyboard is especially useful for
entering small amounts of text, such as passwords and file names.
Customization
You can customize Input Panel based on your personal preferences,
such as inserting text automatically, changing the ink thickness, and
defining the amount of space between the lines in the writing area.

WalkAbout Computers HAMMERHEAD RT User’s Guide – V030105 39
Speech
You can use your voice either to dictate or give commands. For example,
you can dictate to your Tablet PC to enter text into a program. You can
use voice commands to correct any errors, format text that you have
dictated, save documents, switch between programs, move around
within a program, or perform other actions to control any Windows-based
program. As you speak into your microphone, Input Panel changes your
spoken words into text.
Speaking to your computer is often easier and quicker than using your
tablet pen to enter text. It may also be more comfortable, allowing you to
rest your hands and wrists. You can also save thoughts or ideas
immediately, before you forget them. You can use speech features and
your tablet pen at the same time. Use the microphone to enter text, and
then use the pen to correct and format the text.
Handwriting using Microsoft Windows Journal
Microsoft Windows Journal allows you to take notes in your own
handwriting, just like on a piece of paper. You can later convert those
notes to text if you wish or leave them as "ink." In either case, they're
completely searchable. You can also create drawings or graphics that
can be saved or sent to other applications from Windows Journal. You
can even share journal files with non-Tablet PC users by exporting them
as MHTML files, which others can view with Microsoft Internet Explorer
version 5.0 or later, or by exporting them as TIFF images for viewing with
a viewer that is installed by default on Microsoft Windows 98 or later.
How to access Windows Journal
To access Windows Journal, click on Start, All Programs, and Windows
Journal.
How to convert handwriting to text in Windows Journal
• Click the Selection Tool icon on the toolbar.
• Circle the handwriting that you want to be converted.
• Click on Actions in the Menu Bar.
