Using Your Joystick
Clicking
1. First, place your fingers on the joystick.
2. Gently move your finger in the direction you want the cursor to move. The stick detects the
change in pressure and moves the cursor in the corresponding direction.
3. The left and right buttons located on each side of the joystick are the same in function as those on
a two-buttoned mouse. Clicking these buttons makes selections, drags objects, or performs a
variety of other functions depending on the software. To select an object, first move the pointer
over the object you want to select, and then press the left button one time. The functions of these
buttons are software specific.
NOTE The joystick also has the ability to do a left button click if it is tapped.
Double-clicking
Double-clicking is a common technique for selecting objects or launching programs from icons.
Once you have moved the pointer over the object you wish to select, rapidly press the left button
two times. This action is commonly referred to as “double-clicking” an object.
NOTE Double-clicking can also be accomplished by double-tapping with the joystick.
Dragging
Move the pointer to the desired location then press down the left button. While still holding down
the left button, move the pointer to the desired location. Release the button.
Move the pointer to the desired location. Tap the joystick twice quickly as if you were double-
clicking, however do not remove your finger after the second tap. Move the cursor to the desired
location. Lift your finger to finish dragging.
Adjust the joystick settings by selecting Settings/Control Panel/Mouse/Buttons. These settings allow
you to change the orientation of the joystick from right-handed to left-handed, and fine-tune the pointer
movement and timing of clicks.
General Guidelines
The mobile computer uses a Liquid Crystal Display (LCD), which is the type of screen used on many
notebook and sub-notebook computers. One problem experienced on computers with an LCD display,
especially in cold environments, is that the cursor seems to “disappear” whenever the mouse is moved
quickly. To improve the visibility of the mouse cursor, you should:
Enable the “Pointer Trails” feature to add trailing cursors.
Use a slow or medium speed/sensitivity level.
You can combine a higher level of acceleration with a slow or medium speed/sensitivity level. This will

allow you to move the mouse cursor quickly by increasing your finger pressure, while still providing a
finer degree of control when you apply minimum pressure.
NOTE To change the speed of the mouse, from the Start Menu select Settings, Control Panel, and then
choose Mouse to make adjustments.
Connecting an External Keyboard or Mouse
You can use your GoBook MAX computer with an optional external keyboard, numeric keypad, or
mouse. The devices are “ hot swap” capable, which means you do not have to power down the GoBook
MAX to connect these devices to the USB connection located on the right side of the unit.

Using the Battery
Monitoring Battery Power
There are two ways to monitor how much power the battery has left:
1. Click Start, Settings, Control Panel, Power Management; then click the Power Meter tab.
2. Moving the cursor to the battery icon on the taskbar, without selecting anything, is the simplest
way to check on battery power status. The status will show as a pop-up when you mouse-
over the
icon.
NOTE If you do not see the battery icon on the taskbar, enable it in Start, Settings, Control Panel,
Power Management. Choose the Advanced tab and select "Always show icon on the taskbar."
Low Battery Alarms
How your computer responds to a low battery condition can be set by going to Start, Settings, Control
Panel, Power Management, Alarms.
Two different power alarms can be enabled or disabled: the Low Battery Alarm, and the Critical Battery
Alarm. Use the slidebar to set the power level at which the alarms are activated. Click on the Action
button to choose whether the alarm sounds, displays a message, or both.
CAUTION When battery power is low, the Battery LED activity indicator will flash and a warning
will display on your screen. Take immediate action, such as saving files or connecting to the AC
adapter , or data may be lost.
When the computer alerts you that the battery is low, immediately do one of the following:
Save your work and suspend the computer by pressing and releasing FN+Q. Then either connect
to AC power to charge the battery or change the battery if needed.
Connect the AC power adapter
Save your work and suspend to disk (Hibernate) by pressing FN+F10

Battery Charging
When you use the AC adapter to connect your GoBook MAX to a power outlet, the internal battery will
automatically begin to recharge. While the battery is charging, the Power LED activity indicator on the
indicator panel will be flashing. When the battery is fully charged, the Power LED activity indicator will
turn solid.
It will take 4 to 5 hours to recharge the battery. Refer to the following table:
Power Saving Modes
Adjust the default power management settings in the Power Management (Power Options) dialog box in
the Control Panel. The Power Management (Power Options) dialog box allows you to set different
actions to take when the computer is left idle for a certain amount of time.
Suspend Mode
There are several possible settings for suspend mode. You may Suspend to RAM, Suspend to Disk
(Hibernate), or disable suspend altogether, which is not recommended.
Suspend to RAM
In a suspend to RAM, the contents of your computer’ s memory are held intact, while practically all the
rest of the components in your computer either turn off completely, or reduce power consumption to a
minimum. In a Suspend to RAM, your computer remains active but with the minimum possible power
consumption. Return the computer to full power by pressing FN+On. When the computer returns from
suspend mode, the desktop appears with the same files and programs open as when the computer was
suspended. A fully-charged battery can maintain a Suspend to RAM for many hours.
Suspend to Disk (Hibernate)
Suspend to Disk (Hibernate) is similar to turning off the computer, except that the current state of the

computer is copied to the hard disk as a special file. When the computer returns from suspend mode, the
desktop appears with the same files and programs open as when the computer was suspended. Suspend
to Disk (Hibernate) is very useful when you don’ t want to take the time to shut down all open programs
one by one to shut off the computer, only to have to open the same programs and files the next time you
use the computer. This mode is also called hibernation mode.
Initiating Suspend Mode
There are four ways to initiate suspend mode. The settings can be adjusted in the Battery panel profile
dialog box:
The computer will automatically enter suspend mode when not used for a set period of time
Selecting the Standby button in the Shut Down Windows dialog box
Pressing the suspend/system off function key (FN + Q)
Closing the lid (display) if enabled in power settings.
Power Saving Tips
Avoid operating the fax/modem, or audio and video applications when using battery power.
Operating a fax modem, video, or audio equipment increases the computer’ s power requirements.
Decreasing monitor brightness can also save power. Decrease brightness by pushing FN + F2.
Increase it by pushing FN + F3. 
When to Replace the Battery
Over time, the battery’ s capacity gradually decreases. We recommend that you replace your battery
when you notice that it begins to store significantly less charge.
Changing the Battery
Change the main battery pack as follows:
1. Turn off the computer.
2. Disconnect external power .
3. Close the display and turn the computer over.
4. Slide the latch to the un-locked position and slide the battery out of the compartment.
5. Make sure the replacement battery is properly orientated. Insert the battery into the battery
compartment. Slide the latch to the locked position. Check that the latch locks back into position.
6.
Charge the new battery by plugging the computer into AC power.

Heat Considerations
The computer’ s processor has been specially designed to consume as little power as possible, and
generates very little heat. However, working in a hot environment, or working for long periods may
raise the temperature. Your computer takes the following steps to lower temperature:
1. The cooling fan is turned on. You may hear the fan and feel air coming from a vent near the left
front of the computer when this happens.
If the temperature continues to rise:
2. Processor activity is reduced. You may notice a slight loss of performance when this happens.
If the computer overheats:
3. The processor will stop functioning and the computer will shutdown.

Battery Maintenance
Over time, as the battery is repeatedly drained and recharged, battery performance will decrease.
Occasionally, the battery needs to be recalibrated for maximum performance. This is the purpose of the
Battery Calibration application, to restore the battery to maximum performance levels.
To determine if the battery needs to be calibrated, run the Battery Calibration program. The initial screen
indicates whether or not calibration is necessary:
GoBook MAX™ Help

...
However, it is not necessary to open Battery Calibration to check if the battery requires calibration. The
System Monitor will display an alert when the battery requires calibration.
After launching, the Battery Calibration application requires no input from the user. The calibration
consists of four steps:
1. Partial Discharge - the battery is drained to a level below 88 %.
2. Charge - the battery is fully charged to 100 %.
3. Discharge and calibrate:
First, the battery is discharged all the way down to zero. Now the battery is 'calibrated' but not
charged. You may stop the process after this point and let the battery charge outside of the Battery
Maintenance application.
4. Charge - if the Battery Calibration continues running, the battery will fully charged to 100%.
During the process the Battery Calibration application reports the following information:
The Process Status box displays the currently active stage.
The Battery Information fields display status and current parameters of the battery.
Gas Gauge : Level of charge in the battery
Battery Current : Amount of current the charge (or discharge) process is drawing. Note that
this may be zero at times, due to the nature of the charge process.

NOTE The unit will not go into suspend mode while Battery Calibration is running.
CAUTION Do not disconnect AC power while Battery Calibration is running. If AC remains
disconnected for more than two minutes, the application will terminate.
CAUTION Do not remove the battery while Battery Calibration is running. Doing so will cause the
application to terminate immediately.

Customizing Your BIOS Settings
This chapter explains how to use the Setup Utility to modify the BIOS settings. The Setup Utility
displays and allows modification of the GoBook MAX components and the configuration of devices that
are connected to it. This information is used to test and initialize components at start-up time and to
make sure everything runs properly when the system is operating.
The BIOS is installed with a set of default values. You may be able to increase system performance by
changing some of the timing values in the Setup Utility, but this can be limited by the kind of hardware
you are using. In certain circumstances, the system may generate an error message that asks you to make
changes to the CMOS settings using the Setup Utility. This happens when the system finds an error
during the POST (Power On Self Test) that it carries out at startup.
CAUTION It is not recommended that you change any settings since this may cause the unit to not
function properly.

If you are not sure how to configure the BIOS settings we suggest that you load setup defaults on the
Exit Menu or press F9, yes, F10, then yes from any menu. This loads optimized default settings for
normal use.
Using the BIOS Setup Utility
The BIOS Setup Utility allows you to configure your computer’ s basic settings. When you turn your
computer on, the system reads this information to initialize the hardware so that it can operate correctly.
You can use the BIOS Setup Utility to change your computer’ s start-up configuration. For example, you
can change your system's security routine.
Starting the BIOS Setup Utility
You can only start the Setup Utility shortly after the computer has been turned on. A prompt appears on
the computer display that says “ Press F2 to run Setup.” When you see this prompt, press the F2 key and
the system will start the Setup Utility and display the main menu of the utility.
CAUTION Incorrect settings can cause your system to malfunction. To correct mistakes, return to
Setup and restore the Setup Defaults by pressing F9 and selecting yes.

I/O Device Configuration Menu
The CPU communicates with external devices such as printers through devices called Input/Output (I/O)
ports such as serial ports. These I/O devices require the use of system resources such as I/O addresses
and interrupt lines. If these devices are Plug and Play, either the BIOS can allocate the devices during
POST, or the operating system can do it. If the I/O devices are not Plug and Play, they may need to be
set manually in Setup.
On some systems, the chipset manages the communication devices. Other systems have, instead, a
separate I/O chip on the motherboard for configuring and managing these devices.
Many systems allow you to control the configuration settings for the I/O ports. 

Automatically connect to an external RF antenna
PRECAUTIONS
There are no user-replaceable parts within the vehicle cradle, so do not open the cradle case. The
vehicle cradle is internally protected; it resets automatically if there is a power fault.
Do not use the vehicle cradle to charge the computer battery overnight. Turn off the vehicle cradle
at the end of each work day to prevent draining the voltage in your vehicle’ s battery below
starting levels.
Charging Batteries
The vehicle cradle is designed to charge the computer’s battery with voltage from the vehicle battery
while you are traveling between jobs. Follow the procedure below to charge a battery.
To charge a battery installed in the computer
1. Place the computer onto the vehicle cradle, making sure it is securely latched.
2. If charging is required it begins automatically. LED #2 flashes.
3. When the battery is fully charged, LED #2 will be on steady.
Communicating with Other Devices
Connect the external device to either of the USB ports on the back of the cradle, and then place the
GoBook MAX onto the vehicle cradle. You can install or remove the computer from the vehicle cradle
without connecting or disconnecting the cables from the cradle.
Important
A temperature of 0°C to 40°C (32°F to +104°F) is recommended when charging batteries
with the vehicle cradle. Batteries may not charge successfully outside this temperature
range. The battery will not charge at >45°C (113°F).
If you charge your battery daily, rely on the gas gauge reading to determine battery
capacity. The gas gauge displayed by the Battery Slope may show that the battery is full,
but charging continues. This happens because the charging process is trying to put a little
more capacity into the battery. External power can be removed at this time since the
battery is virtually full.
If your battery is new or has not been used for several weeks, rely on the indicator light to
determine when the battery is fully charged. The gas gauge is unreliable in these cases; it
may read 100 percent, but the actual capacity is only 10 percent.

Surge Protection
A large number of computer and high technology equipment damage is directly related to AC power and
telephone line problems. These problems can include surges, spikes, noise, interference, and weather-
related problems, which in turn can cause glitches, hang-ups, crashes, performance slow downs, and
down time with computer equipment. The market is flooded with hundreds of AC power line surge
suppressors advertising high performance surge protection; only a few of them actually provide
adequate protection.
This section provides guidelines for selecting a quality surge suppressor to be used with your GoBook
MAX, and it helps identify a few sources for products with acceptable performance.
Selecting the Right Surge Protection
Consider the level of quality you need when selecting a surge suppressor. This depends on factors such
as surge environment, the type of equipment to be protected, and the quality of the electrical wiring and
service.
Surge Environment
Surge environment refers to the damage potential from electrical surges in a particular geographical
area. A high quality suppressor should be used if there is frequent lightning activity in the area and the
location service is fed by overhead utility poles.
Type of Equipment to be Protected
If the computer is equipped with a modem, the modem should also be surge protected. Protecting the
power line without protecting the modem line provides only partial protection.
Quality of Electrical Wiring and Service

...
Wiring should be up to current NEC standards and have verified good AC grounds. It is important that
your computer system be plugged into a grounded AC outlet when charging and that all peripherals
connected to your system reference the same AC ground.
Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors such as Sutton Designs, APC, and
Panamax. When you are looking for a surge suppressor, consider these things.
Expect to pay at least $50 for a good quality surge suppressor.
The surge suppressor should be a UL 1449, 497, and 1283 listed for surge suppression, modem
surge protection, and RFI/EMI noise filtering respectively.
The surge suppressor should have diagnostic LEDs that verify good AC ground, proper wiring,
and proper surge operation. Lighted on/off switches are not recommended since they can produce
electrical noise.
The Joule ratings should be a minimum of 480 Joules for the AC surge circuit.
The Joule ratings should be a minimum of 240 Joules for the modem.
The modem surge circuit should present low capacitance to the modem line or it will slow the
transmission rate. Capacitance should be specified at less than 50 picofarads.
Quality surge suppressor manufacturers generally offer a lifetime warranty.
Consider obtaining a protected equipment coverage policy which insures the equipment in the
event of surge damage.
The devices that will be attached to the computer also need to be surge protected.

Hard Drive Care and Handling
All hard drives contain media for data storage in the form of a rotating disk, read/write head(s), a motor,
and electronics for interfacing and control. Drives can be susceptible to damage from severe shock and
other stressful environmental impacts. The degree of susceptibility to damage is directly related to the
individual hard drive and the mounting system employed.
When reading or writing to the hard disk , the head is “ flying” on a thin layer of air, micro-inches above
the disk. A shock can cause the read/write head to contact the spinning disk, resulting in immediate loss
of stored data and possible physical damage to the disk. It could also create loose debris in the drive
enclosure that may cause progressive damage over time.
GoBook MAX™ Help
CAUTION
Always use an approved stylus or your finger.
Never use sharp, hard, or abrasive implements on the touch screen such as ball point pens,
pencils, or keys. They could damage the screen.
To clean the touch screen panel, apply a household glass cleaner to a soft, clean, dry cloth
and wipe the screen.

To reduce exposure to high operating shocks, the GoBook MAX uses power modes for the hard drive
that prevent the read/write heads from being positioned over the disk when it is not being used: idle
mode and standby mode.
You can reduce the risk of damage to the hard drive and increase the reliability of the hard drive and
data integrity by following the recommendations below.
Internal Hard Drives
Do not intentionally drop the computer. The unit is designed to withstand the day to day rigors of
the mobile environment and provide years of reliable service. The useful life of the product can be
enhanced by not intentionally abusing it.
Whenever possible suspend the unit by pressing FN+Q before moving it from one location to
another. This will unload the read/write heads and spin down the disk.
Maintain the environmental seal of the computer by keeping PC Card access door closed and
latched. Also avoid exposing the unit to extreme temperatures or moisture when the door is open.
Periodically backup or archive important files and data.
External PC Card Hard Drives
Each PC Card hard drive manufacturer provides specific guidelines for the care and handling of the
product. In addition, follow these recommendations:
When the PC Card hard drive is not inserted in a PC Card socket, store the hard drive in a
protective carrying case. This will help protect it from inadvertent shocks.
Always use care when handling the hard drive. Do not drop, bend, flex, or crush it.
Avoid exposing the PC Card hard drive to extreme moisture, heat, or sunlight.
Keep all debris out of the connector to ensure good electrical connections.
There are no user repairable parts in the PC Card hard drive. Do not attempt to disassemble any
part of the hard drive. The warranty will be voided if drive seals are broken or screws have been
removed.
Periodically backup or archive important files and data.
If you encounter or suspect hard drive problems, you can run SCANDISK, which provides a description
of file usage and syntax on selected drives. SCANDISK will identify any failures on the hard drive and
prompt you for corrective action based on selected options. If problems are found, it may be necessary
to run SCANDISK several times to determine the extent and severity of the problem. SCANDISK may
discover multiple bad clusters. Up to ten bad clusters can be allowed before returning the computer for
service. After you have run SCANDISK and the problem persists or becomes more severe, or if
SCANDISK finds more than ten bad clusters, return the unit for service.

Batteries
The battery does not charge
To prevent possible damage to the battery, the system will not allow a charge if the battery
temperature is extremely hot or cold (such as in a closed, unattended vehicle). If possible, charge
the battery in a location with a moderate temperature of around 20°C (68°F).
If possible, turn off the computer while the battery is charging.
If the battery is new or has been stored for a week or more, follow this procedure:
1. Make sure the computer is turned off.
2. Remove the battery.
3. Connect the AC adapter to the computer and an AC wall outlet, and then turn on the computer by
pressing the FN+On (spacebar).
4. Reinstall the battery.
5. Allow the system to remain idle for one hour with the AC adapter connected to the computer.
The Charging LED activity indicator blinks when the battery starts charging.
6. If the battery still fails to charge after an hour, remove the battery, wait several seconds, and then
install it again.
If the battery does not begin charging within several minutes, return the unit for service.
The batteries take much longer than seven hours to charge
Under moderate temperatures, about 21°C (70ºF), the computer’
s battery takes approximately 4 to
5 hours to completely charge. 
Under extremely cold or hot temperatures, however, the battery can
take up to 16 hours to fully charge.
The batteries don’ t last very long

maintained batteries eventually need to be retired. Consider replacing the battery if you are not
getting the usage you need from it.
The gas gauge isn’ t full after charging the battery
This may indicate that the charging process terminated prematurely.
The gas gauge reads “ full,” but the indicator light is still blinking
If you charge your battery daily, rely on the gas gauge reading to determine battery capacity. The
charging process may continue even if the gas gauge reads full. External power can be removed
because the battery is virtually full.
My battery seems to have less and less capacity
As your battery ages, the maximum capacity that it can hold naturally decreases, and even the best
maintained batteries eventually need to be retired. Consider replacing the battery if you are not
getting the usage you need from it.

The modem dials and the answering modem generates tone, but our modem does not begin the training
sequence to establish a connection
Although the problem may appear to originate from the computer, the source of the problem is the
answering modem.
Try setting up the answering modem to generate the correct V.22 tone, which can usually be done
by sending an AT command to the modem.
Add %!1300AO to the initialization string. If used, this command must be sent immediately
before the command to dial the desired phone number and sent again before re-
dialing the number
since the modem will default to the original setting at the end of the session.
