Unit Setup
1. Install the battery
The Lithium-Ion (Li-Ion) battery and battery
cover are shipped detached from the unit.
Insert the battery into the compartment so
the connectors on the battery mate with the
pins in the battery compartment. Press
firmly. Place the battery door over the
battery, with the flat side of the battery door
at the top.
Remove the cap from the end of the stylus
to expose a Philips screwdriver, or use a
small #1 Philips head screwdriver to finger-
tighten the four screws in the battery door.
NOTE: DO NOT use the screwdriver part
of the stylus on the touchscreen or it will scratch your screen.
Only use the spring-tip end of the stylus.
2. Charge the battery
The AC adapter that ships with your unit has multi-national plugs
that fit almost every electrical outlet in the world. Connect the
appropriate AC plug to the AC adapter for your country. Plug into
an electrical outlet and plug the barrel end of the AC adapter into
the unit.
Warning! Be sure to only use the AC adapter included with your
unit. Use of other adapters will void the product warranty.
IMPORTANT: Fully charge the battery once it’s installed in the
unit. The battery gauge may not be accurate until it has
been fully charged at least one time, which should take
approximately 4 ½ hours. The battery LED (right side of
unit
)
will turn

3. Install the screen protector
To keep the touchscreen clean and protected, install the screen
protector following the instructions provided in the screen
protector package. Unprotected screens become scratched and
scuffed over time. Screen protectors extend the life of the display
by providing a protective and replaceable barrier between abrasive
grit and the surface of the display.
Screen damage associated with failure to use a
screen protector is not covered under warranty.
4. Attach the hand strap
Attach the hand strap to the back case, as shown.
5. Turning your unit on and off
The unit should boot up when the battery is installed. If not, press
and release the green Power key on the keypad. To turn your unit
off, press and release the Power key again.
One of the most convenient features of your unit is “instant on”
and “instant off” (also known as “suspend/resume”). There is no
waiting for the unit to boot up every time it is turned on. “Instant
on” does not occur on the first boot-up.
When the unit first turns on, the message “Tap the screen to set up
your Windows Mobile-based device” will appear.
6. Align screen
The Align Screen message will display a series of targets to tap in
sequence on the screen. Use the stylus to tap the targets firmly and
accurately. Sometimes you need to repeat the alignment procedure
more than once to provide a satisfactory alignment.
7. Location – time zone
Select your time zone location, set the time and date to the correct
values and tap Next.
8. Password – lock (optional)
You do not have to provide a password unless you are concerned
about unauthorized use. To eliminate using a password, tap Skip.

6
If you opt for password protection, the password must be entered
every time you turn the unit on or use the Power key to resume
operation.
WARNING: BE CERTAIN TO REMEMBER THE
PASSWORD. The only way to recover from a forgotten password
is to perform a Clean Boot and you will LOSE all application
software, licenses, settings and data on your unit. See page 12 on
how to perform a Clean Boot.
9. Using the expansion ports
To access the expansion ports, use the
Philips screwdriver end of the stylus or a
small #1 Philips head screwdriver to
rotate the two quarter-turn fasteners
counter-clockwise and remove the Expansion Cap.
Under the Expansion Cap is a Secure Digital (SD) expansion slot.
(SD cards greater than 2GB are not currently supported). There is
also a CompactFlash (CF) type II slot and an 8-pin proprietary
connector (for third-party developer use).
Gently insert cards with the front of the
card facing toward the display side of the
unit. Insert the card into the slot and
release; the card should catch in the slot.
Always push the card in straight, never
at an angle or forced.
To eject an SD card, gently press the top of the card to release it.
To eject a CF card, press the eject button located next to the CF
card.
NOTE: DO NOT use the unit without reattaching the cap and the
boot. The unit is NOT sealed when the cap or boot is off and water
damage can occur, voiding the warranty.

10. I/O Boots
There are two types of boots available. The boots can be swapped
by loosening the screws pointed out in the picture below.
USB I/O Boot Serial I/O Boot
Both boots have a mini-USB client that uses a USB 2.0 A male to
mini-USB B 5-pin cable (included with the unit). The Mini-USB
can be used to connect to a personal computer (PC).
USB I/O Boot: This boot has a mini-USB client, a USB host port
(to connect to USB client devices) and an audio jack that is wired
for a headset with a mono speaker(s) and microphone
combination. (It is not for stereo headsets.)
NOTE: Many USB host peripheral devices supported on personal
computers are not supported by this unit. There are two classes of
USB devices that have native support in the OS:
1.) USB Human Interface Devices (HID). Examples include
keyboards and some barcode scanners.
2.) USB Mass-Storage devices. Examples include memory keys,
hard disks, some digital cameras and memory card readers.
Before purchasing a USB peripheral, check with the manufacturer
to ensure that it will operate with one of these natively supported
USB classes. Some devices have no applicability in Windows
Mobile. For example,mice do not make sense to use with your
unit because it is designed to be touchscreen operated.
Serial I/O Boot: This boot has a mini-USB client, and is for use
with serial devices. NOTE: COM1 is always reserved in software
for the 9-pin port, even if you don’t have a unit with a serial boot.

Working with the Unit and the Battery
Battery life: The Lithium-Ion (Li-Ion) battery life is dependent
upon the application and operating environment. Repeated usage
of the keypad and display backlight, heavy usage of the 802.11
(Wireless LAN or WLAN), cold temperatures, GPS, and high
power consumption CF and SD devices can all reduce the battery
life. Other factors that may have some impact on battery life
include heavy usage of the Bluetooth radio and heavy processing
by the CPU, but these factors are typically less significant.
Tips for extending the battery life:
- Keypad backlight:The default is off. Using this backlight
could reduce your battery life by up to 25%. For information
on changing the backlight settings, see page 17.
- Display backlight:The default is on, at 65% of full brightness
Minimize the amount of time the backlight stays on when
idle. Dim the backlight to only as bright as required to view
the display.
- 802.11: If your unit comes with 802.11 (WLAN) installed, use
ONLY when necessary. Turn off when not needed.
- Cold temperatures: Keep the unit as warm as possible. If
feasible, keep it inside your coat or a vehicle when not in use.
- GPS: Ensure that the GPS-aware applications that
communicate with the GPS are closed when not in use. The
Today screen indicates if the GPS is running.
- Expansion ports: Select low-power consumption CF and SD
cards and use them only when necessary.
- Auto features: Tap Start / Settings / System / Power /
Advanced. To conserve battery power, specify your unit to
turn off in a short time if not in use.
Charging the battery: The battery can be charged in the unit or
separate from the unit with an external battery charger (sold
separately, as an accessory). Connect the appropriate AC plug to
the AC adapter. Plug into an electrical outlet and plug the barrel
end of the AC adapter into the unit. The unit will be fully charged
in about 4.5 hours. A full charge is indicated by the battery LED
(right side of the unit) turning green. The manufacturer

9
recommended temperature range for charging the battery is
between +32°F and +113°F (0 C and +45 C). If the battery
temperature is outside of this range, the battery will not charge.
Warning! Be sure to only use the AC adapter included with your
unit. Use of other adapters will void the product warranty.

Changing the battery: The battery is designed to be quickly
changed. The unit saves enough power that if you swap the
battery within approximately one minute, it will not trigger a
reset. If the saved power runs out before the new battery is
installed, the unit will reset. This will not impact saved data,
programs or configuration, however unsaved data will be lost and
the time settings will need to be reset.
To change a battery, perform the following steps:
1. Close open applications and save data in case the battery
exchange takes too long.
2. Remove the hand strap from the unit.
3. Enter the Replace Battery mode (ensures that alarms will not
wake up the unit while changing the battery). Press and hold
the Power key and tap Replace Battery. See page 12.
4. Use the supplied stylus or a small #1 Philips head screwdriver
to loosen the four screws in the battery door.
5. Remove the battery from the unit.
6. Quickly insert the replacement battery onto the unit.
7. Place the battery door over the battery, with the flat side of
the battery door at the top of the unit. Use the stylus or
screwdriver to finger-tighten the four screws.
8. Replace the hand strap.
9. Turn the unit ON to resume operation.

10
Calibrating the battery: The battery has an internal gauge that
provides an estimate of the amount of energy in the battery as it
charges and discharges. If your battery is showing inaccuracy in
the power gauge or large jumps in capacity, (i.e. the power is
reading 50% and goes dead shortly thereafter) it may need
calibration.
Tap Start / Settings / System / Power / Calibration to see if the
message reads Calibration recommended or Calibration not
necessary.
If calibration is recommended or the battery is reporting
inaccurately, perform the following:
1. Plug in the AC adapter. The unit MUST stay charging while
doing the calibration or you may need to restart the process.
2. Ensure the temperature is between +32°F and +113°F (0 C
and +45 C) while charging.
3. Tap Start Calibration.
4. During the calibration process, the Power key is disabled
temporarily and the backlight is turned up to 100%.
It takes up to 25 hours to complete the calibration. A notification
will state Calibration is complete. It is recommended to not use
your unit during the calibration process, so calibrate when the
use of the unit is not required. If you wish to stop the calibration
process, tap Start / Settings / System / Power / Calibration /
Stop Calibration.
Possible error messages that can occur during calibration:
Error Message Solution

data, and real-time clock settings will be lost. Internal GPS
parameters will be reset to their default settings. To take the unit out of the shutdown
mode, press the power key and the unit will boot up. NOTE: While in shutdown mode,
the battery LED does not work, but if the AC adapter is plugged in, it will still charge.
Reset: Stops all running programs and restarts the unit. No file system data is lost,
only open or unsaved files will be lost. All registry settings, control panel, personal
information, GPS settings and databases are preserved.
Perform a Clean Boot
WARNING: All application software, (installed by
the factory and the customer) licenses, settings
and user data will be cleared if you perform this function!
Hold down the Power key and press the right soft key to
display a countdown. Continue to hold down both keys until it
counts down to zero, followed by a brief appearance of the boot
screen. Continue to hold both keys down until a screen appears
warning that if you continue, this operation will clear the persistent

13
store. Follow the instructions on the screen ONLY if you want to
completely clear your unit.
NOTE: GPS applications installed will need to be reinstalled, but
certain configuration parameters of the internal GPS receiver
(baud, parity, etc.) will remain unchanged.
Storage memory
Unlike many handhelds which can lose data if they lose power, all
your data is always stored in non-volatile persistent storage
memory. Losing power will not impact saved data or configurations
other than the real-time clock. This means that you do not have to
use a RAM backup utility to protect your data. However, you can
lose data by accidentally deleting or overwriting it. As with any
computer system, we recommend that you regularly backup your
data to removable media or to a PC.
Accessing storage memory using file explorer
File Explorer (Start / Programs / File Explorer) lets you browse
the contents of folders on your unit. To easily delete, rename, or
copy an item, touch and hold the item.
NOTE: Unlike PCs, Windows Mobile does not support a Recycle
Bin. Once a file is deleted, it cannot be recovered.

GPS
Tap Start / Settings / System / System Information / Wireless
to see if your unit has built-in GPS. If you do, COM2 is the
dedicated hardware port for the built-in GPS (COM1 is dedicated
to the external 9-pin). The GPS is compatible with applications
that accept the NMEA position information using a default setting
of 9600 bps.
If you want to use GPS capabilities on your unit, you must install
a GPS-aware application.
The GPS is turned on when a GPS-aware application accesses it,
and it is turned off when all GPS-aware applications are closed.
To see if the GPS is on or off, refer to the Today screen. You
cannot modify its state from there. Running the GPS will impact
the Nomad’s battery performance, so the GPS should be turned
off when not in use.
GPS settings: To allow your unit to use multiple GPS-aware
applications to obtain GPS data simultaneously, your unit can
manage access to your GPS. If you are using only one GPS-aware
application, these settings do not need to be changed.
To use multiple GPS-aware applications, tap Start / Settings /
System / GPS and select the following tabs:
Access: The GPS Intermediate Driver allows multiple
applications to access the GPS receiver. This driver is
disabled by default. To enable the GPS Intermediate Driver,
select the Manage GPS automatically check box.
Hardware:COM2 is the hardware port dedicated for the built-
in GPS. Verify that COM2 is selected. The internal GPS
communicates at 9600 baud by default. If this baud setting
has been modified by a third party program, you will need to
adjust the baud rate to match the baud rate of the receiver.
Programs: Programs that use GPS need to know which port to
use to access GPS data. Ensure that the COM port on the
GPS-aware application is set to the same port as shown in the
Programs tab of the GPS applet. The programs port must be a
different port than the hardware port. NOTE: Some GPS-
aware applications may not communicate over GPD ports.

15
If you are unable to connect to the GPS using the default GPS
settings, you can restore it to factory default settings by
performing a shutdown. See page 12.
Using the stylus
Ensure that you DO NOT use the metal screwdriver of the stylus
on the touchscreen; it will scratch your screen. Only use the
spring-tip end of the stylus.
Use the stylus to navigate and select objects on the screen.
Tap: Tap the screen with the stylus to select or open an item.
Tapping is the same as clicking the left button on a PC mouse.
Drag:Hold the stylus on the screen and drag across the screen to
select text and images.
Touch and hold: To access a pop-up menu, touch and hold the
stylus on an item name. A circle of dots will appear to indicate
that a pop-up menu will soon appear. This action is similar to a
right mouse click on a PC.
