released from the AT870, then lift it out.
2.3.2 Installing the battery
Insert the bottom of battery into the sunken place located in battery compartment, and press the
battery latch to the above until the battery is installed completely.
2.4 Battery discharging
Several factors determine the life of your battery such as extreme temperatures, input devices, and
your usage, but generally you can use AT870 for 6~12hours.
If the AT870 is not on external power and battery pack is removed, it will enter suspend mode.

Figure8. Memory Allocation
4. Resetting the PDA
When the AT870 completely stops responding for your command, or an application is locked up and
does not respond, and when you want to upgrade the firmware, it may be necessary to perform a
reset.
Caution
Always attempt a Warm reset before initiating a Cold reset. Once you initiate a cold reset, all
applications are forcibly closed and working RAM and files are cleared.
It is a good idea to store important data in the resident (Flash Disk) for this reason.
Warning
Do not use force or a sharp object like paper clip to press the reset button. Use the stylus for
that purpose. Sharp object like paper clip could puncture the seal of the reset key.
4.1 Warm Reset
When you should perform the warm reset?
When you cannot turn on or off a program, or execute other programs because of “hang”-the
system error that stops responding. The “warm reset” for recovering the AT870 is to press R/S
button on the front of AT870. This method not guarantee that cashed disk data will be saved, so
transactional data maybe lost during the reset.
Procedure to Warm Reset. To initialize warm reset, press and hold the <Reset> key.
After Warm Reset
• The splash screen will appear shortly.
• The desktop appears with the application shortcuts on the screen.
• The custom settings in the registry are persistent.
• The RF Network PC Card if present, connects to the network system.
4.2 Hard Reset (cold reset)
When you should perform the cold reset?
If the performed reset method fails to restore system operation, it may be necessary to perform a
hard reset. This is a boot method that formats the object store to clean data and registry information

AT870 User Reference
17
from the AT870 system and restores them to their factory-default state.
This will erase the memory in the AT870, including all applications and data files found in the object
store (user store).
A Hard reset is a complete reset of the PDA in which all applications are forcibly closed and working
RAM and files are cleared.
Hard Reset Procedure. To perform a Hard reset, simultaneously press the <Reset> key with the
stylus while pressing the <power> key.
After Hard Reset.
When a PDA goes through the Hard reset sequence, it clears the working RAM and initializes the
file system.
• The splash screen will appear shortly.
• You will be asked to recalibrate the touch screen. Press the <ESC> key to circumvent
recalibration.
•The desktop appears with the application shortcuts on the screen.
• The custom settings in the registry are persistent.
• The RF Network PC Card if present, connects to the network system.
• The application saved in Flash Disk will not be deleted after cold reset (refer to section 5 Flash
Disk)
5. Flash Disk
In addition to the RAM-based storage standard on Windows CE .NET terminals, the AT870 is also
equipped with a Flash Disk, and all the application and data in the Flash Disk can be persisted in
its own condition after the hard reset. From this point of view, it is a kind of very useful method to
keep important application and execute user’s own application automatically after the hard reset.
To save your application program, please keep these following steps in your mind.
5.1 Hard reset
1. At first copy an execute file you want to re-execute.
2. Double-tap My Device > Flash Disk > Open Start folder >Open Hard Reset folder
3. Paste the copied file in the Hard Reset Folder.

If you don’t want to execute the application copied in the Flash Disk, after the hard reset is
performed, press the “Fn” key during the hard reset.
5.2 Warm reset
1. At first copy an execute file you want to execute after warm reset.
2. Double-tap My Device > Flash Disk > Open Start folder > Open Reset folder
3. Paste the copied file in the Reset folder.

If you don’t want to execute the application copied in the Flash Disk, after the Warm reset is
performed, press the “Fn” key during the Warm reset.
5.3 Return back to the existing place
When a PDA goes through the hard Reset sequence, it clears the working RAM and initializes the
file system, but because of Flash Disk you can make your files return back to their existed place
after the Hard Reset get performed. This method is also very useful to configure your system
without any action after the hard Reset.
To make files get replaced:
Copy files you want to replace after the hard reset.
Double-tap My Device > Flash Disk > Open CopyFile
Figure 7. Click Copy File Figure 8. Copy files you want to replace
To make your files return back to the background screen (\Windows\Background) after Hard Reset,
paste your Files into the Desktop folder.
To make your files return back to programs (\Windows\Programs) folder after Hard Reset, paste
your Files into the Programs folder.
To make your files return back to Windows (\Windows) after Hard Reset, paste your Files into the
Windows folder.

a very useful method to restore your AT870, when you perform the hard reset, and even if it is
discharged completely.
The main function of registry:
1. Makes connection between WLAN and AP.
2. Execute RegistryBackUp program and save registry.
3. Restores the connection between WLAN and AP after hard or soft reset.
