Chapter 1 - Introduction

The battery gauge consists of five LEDs, which indicate the approximate charge remaining on your computer. When all five lights are lit, the battery charge is full. As you use the battery, the lights will turn off from top to bottom, indicating the amount of charge that remains. Each light represents approximately 20% of the full charge. See Chapter 2 “Batteries and Charging Procedures” for more detailed information on the battery gauge.

The charge status indicator is lit whenever external power is available. It blinks as the battery charges and remains a constant green when the batteries are fully charged. The indicator identifies a positive connection when the HAMMERHEAD XRT is in the docking station with an external power source. The indicator will be green when external power is connected.

The indicator flashes as the internal hard disk drive is accessed.

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: When turning on the machine, DO NOT press the on/off button twice in rapid succession. A double press 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.

The on/off button is recessed to prevent accidentally turning the unit on or off. The HAMMERHEAD XRT will perform its self-check 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 XRT. 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 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.

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

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 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 it 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 Handwriting directory of the Control Panel.

The HAMMERHEAD XRT 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 pen directory of the Control Panel. Confirm the display is on the appropriate setting before attempting to realign the pen.

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

Chapter 2 – Hardware Operation

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.

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

Chapter 2 – Hardware Operation

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 XRT has the capability to run on one or two batteries in the field. The unit does not require both batteries to run. The twobattery 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

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

Chapter 2 – Hardware Operation

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 XRT 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.

The HAMMERHEAD XRT requires at least 14.5 v DC for fast charging. Do not use any external power source other than the AC or DC adapters provided with the HAMMERHEAD XRT. 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

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.

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

Chapter 2 – Hardware Operation

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 be 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.

• Do not let children play with batteries.

WalkAbout Computers HAMMERHEAD XRT User’s Guide – v030105

Chapter 2 – Hardware Operation

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 –30°C to

55°C, preferably room temperature.

• Store your battery at temperatures between –20°C to 45°C. Do

not store batteries in fully discharged states.

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 batteries in less time, compared to the current WalkAbout external battery charger. Typical Charge Time per battery is 1.7 hours.
