! Soft Reset Button — Lets you do a “soft reset” to the MobilePro in 
case of malfunction. Your data is preserved if it has been saved in a 
file. Use your stylus to press the soft reset button. 
The reset button design requires the use of 
the stylus. Only use the MobilePro 900 stylus to reset the system. Use 
of another tool can damage the MobilePro. 
! Speaker — Lets you listen to digital audio. You can program 
MobilePro audio to remind you of appointments, notify you of 
operation events, or play application-associated sounds. 
Opening the Display Panel 
Follow these steps to open the display panel. 
1. Slide the display panel latch to the right.

Using the Stylus 
To use the stylus, follow these steps: 
1. Open the MobilePro display panel. 
2. Locate the stylus holder on the lower right side of the display 
panel (see “Around the Front of the System” earlier in this 
chapter). To remove the stylus, slide it away from the unit. 
MobilePro 900 Stylus 
Although you can use your fingertip to activate 
the touch screen, never use hard-pointed or sharp objects. These 
objects can damage the touch screen. 
Never use a ball-point pen on the touch screen.  
The MobilePro 900 warranty does not cover damage to the touch 
screen caused by a ball-point pen or other sharp objects. 
3. Gently touch the pointed tip of the stylus to the screen to select an 
object. You can touch, tap, or double tap objects on the MobilePro 
touch screen.  
Note   The touch, tap, and double tap act just like a point, click, and 
double click of a mouse.  
See “Using Windows H/PC” in Chapter 3 of this guide for additional 
information about using the stylus. 
4. When you are done using the stylus, return it to its convenient 
holder in the MobilePro. 
  
						

							 
2-10 Introducing the MobilePro 
Using Power Sources 
The MobilePro 900 can be powered using the AC adapter or the 
system’s main battery, making it a truly portable system. The 
MobilePro also contains an internal data backup battery whenever the 
unit is connected to an AC power source.  
Read the following sections for information about using the 
MobilePro’s power sources. 
Before using the system for the first time, 
charge the MobilePro continuously for 6 to10 hours to fully charge the 
main battery. Allow the 6 to10 hours to pass even if the indicator light 
changes from amber to green before the 6 to10 hours have passed.  
To protect your data, do not use the system until the battery is fully 
charged. Recharge the battery whenever the battery charging LED 
lights amber. 
You must repeat this full 10-hour charge cycle only if the battery 
becomes fully discharged. 
 
Determining Battery Status 
You can determine battery status by using the power icon on the lower 
right-hand side of the taskbar or through the power icon in the control 
panel. The icon on the taskbar displays as an electrical plug when the 
battery is fully charged (battery charging LED lights green) or as a 
battery while charging (battery charging LED lights amber). 
To display battery status, use one of the following methods: 
! Double tap the battery/plug icon on the taskbar, if present. 
! Go to Start, Settings, Control Panel, and double tap the Power icon.  
						

							 
Introducing the MobilePro  2-11 
If you receive a message indicating that the 
main battery is very low, immediately connect the AC adapter to charge 
the battery.  
You cannot use your MobilePro when the battery lock is in the unlocked 
position. The system displays an error message. 
The battery does not charge when the battery lock button is in the 
unlocked position. 
 
Recharging the Main Battery Pack 
The main battery pack contains rechargeable lithium ion cells. 
Recharge a battery pack when you see the following message 
displayed on your screen: 
Main Batteries Very Low 
To recharge a battery pack installed in the battery bay, connect the AC 
adapter. See “Connecting the AC Adapter” in Chapter 1. 
The battery charging LED indicates the charging status of the main 
battery pack when the MobilePro is connected to an AC power source.  
The LED status is displayed as follows: 
! Lights amber while charging. 
! Lights green when fully charged. 
It takes approximately 5 hours to recharge a fully depleted battery pack 
regardless of the system’s power state. However, if the main battery 
has been depleted for a prolonged period, you must allow 6 to 10 hours 
for the main battery to fully recharge. 
Note   Through normal use, the capacity of a battery pack gradually 
declines. Should you notice that the battery does not stay charged as 
long as expected, it is probably necessary to replace the main battery 
with a new one. Please see “Replacing the Main Battery” later in this 
chapter. Depending upon use, a battery pack should recharge from full 
depletion approximately 300 times during the life of the battery.   
						

							 
2-12 Introducing the MobilePro 
Managing MobilePro Power 
When your MobilePro is connected to an AC power source and the 
main battery is removed from the system, be sure to replace the main 
battery before disconnecting the AC adapter to prevent possible data 
loss. 
The MobilePro’s internal data backup battery 
provides power to maintain the memory contents for a limited period of 
time when the main battery is removed and the unit is not connected to 
an AC power source. The backup battery does not provide sufficient 
power to operate the system. 
Do not remove the main battery from the unit for an extended period of 
time unless the unit is connected to an AC power source.  
Replacing the Main Battery 
Note the following when replacing batteries: 
! If the main battery becomes weak, the MobilePro automatically 
turns off. Recharge or replace the main battery immediately if the 
power goes off. 
! The MobilePro backup battery maintains your data for several 
hours whenever the main battery is depleted or removed. 
If you fail to replace a depleted main battery 
for an extended period of time and the backup battery is weak, the 
contents of the MobilePro memory and all user data may be lost. 
Should you notice the life of a charged battery pack is short, replace it 
with a new one. Use the following procedure to replace a battery pack. 
1. Save your data, turn off unit power, and close the display panel. 
Disconnect any cables attached to the unit, such as the PC Connect 
cable. 
2. Have a lithium ion battery pack available. 
3. Remove the battery pack as follows:

Precautions 
Follow these precautions when using your MobilePro and AC adapter. 
! Always plug the AC adapter cord into an easily accessible outlet. It 
is important to be able to easily shut off power by unplugging the 
AC adapter if needed. 
! Avoid dropping or bumping the MobilePro or the AC adapter. 
! Do not stack heavy objects on the MobilePro or the AC adapter. 
! When using the AC adapter, make sure the power source falls 
within the unit’s compatible range of 100-240 volts AC. Never use 
the AC adapter if the voltage falls outside of this range. (Watch for 
this when traveling to other countries.) 
! Turn off the MobilePro power before attaching or removing 
devices. 
! Do not push any foreign objects into the MobilePro bays, 
connectors, and slots. 
! Avoid using the unit or AC adapter for extended periods in direct 
sunlight. 
! Do not use the unit in humid or dusty environments. 
! Turn off the MobilePro power before cleaning the system. 
! Avoid exposing the MobilePro or AC adapter to extreme changes 
in temperature or humidity. If it is unavoidable, allow your 
MobilePro to adjust to room temperature before use. 
! When cleaning the system, use a soft, clean, slightly damp, almost 
dry cloth. Avoid wiping the display surface with abrasive material, 
including rough fabric. Do not use a cleaning solution; this may 
damage the plastic. 
! If the AC adapter becomes extremely hot, unplug the adapter and 
let it cool. 
! Keep the AC adapter away from the IrDA port to ensure stable 
communication/transfer operations.
