Replacing the Backup Battery
Important

same time. Doing so causes all data stored in memory to be deleted.
•Should the main battery and the backup battery both require replacement, be sure to
always replace the main battery first.
•Be sure to replace the backup battery as soon as possible whenever the following
message appears on the display: “Backup Battery Very Low To prevent possible
data loss, replace or recharge your backup battery according to the owner’s
manual.”

							33 Charging the Battery Pack
1. Install the battery pack into the CASSIOPEIA.
2. Attach the AC adapter to the cradle and place the CASSIOPEIA onto the cradle.
•Charging starts automatically as soon as you place the CASSIOPEIA onto the cradle.
•The charge indicator is amber while charging is in progress, and turns green when
charging is complete.
•It takes about five or six hours to reach full charge.
•You can use your CASSIOPEIA while the battery pack is charging.
Important 
•Do not use the CASSIOPEIA while it is charging for the first time after you
purchased it or for the first time after you installed a newly purchased battery pack.
•If the battery pack does not achieve full charge after the normal charge time, unplug
the AC adapter from the CASSIOPEIA to stop charging.
Remove the CASSIOPEIA from the cradle after charging is complete.
The following illustration shows how to connect the AC adapter directly to the
CASSIOPEIA for charging.
•Charging starts automatically as soon as you attach the AC adapter to the CASSIOPEIA.
•Direct connection charging conditions are the same as those described for cradle
charging above.

Resetting the Unit
“Reset” is similar to a computer reboot. Performing a reset deletes any data that is in
the process of being input or edited, without yet being saved. Data stored in memory
and all settings, however, are retained.
Perform the reset operation whenever the unit fails to operate correctly due to
operational error or some other abnormality. Any of the following symptoms indicate
that reset is required.
•Failure of the unit to respond when the screen is tapped or a button is pressed
•The hourglass icon remaining on the screen
Performing a Reset
1. Use the stylus to press the RESET button.
•The unit performs a reset followed by a memory check operation.
If no data error is found, the following two screens appear on the display in
succession.
• Startup screen
• Desktop
2. Normal unit operation is possible after the desktop appears.
•Memory data and settings are retained when you reset the Pocket PC.
Important
If the above operation does not solve the problem, perform a full reset (memory
initialize, page 36). 
						

							35 Memory Error Message
If the memory check operation that the unit performs when the RESET button is
pressed detects a data error, the following message appears on the screen instead of the
startup screen.
“A problem with memory contents has been found. Press [Action] to continue with
the reset procedure, which restores normal system operation.
Note that if the system determines that user memory cannot be repaired, it will
delete all user data currently in memory.
See the User’s Guide for details about initializing memory.”
This message indicates that the memory error is fatal and so recovery is impossible.
Press the [Action] control to execute a full reset (memory initialize), which deletes all
data stored in memory.
•Pressing the [Action] control should display the Startup screen followed by the touch
screen calibration screen. Perform steps 5 through 6 under “Initial Setup” on page 12
to set up the unit.
•If pressing the [Action] control returns to the desktop without displaying the startup
screen first, see the following explanation for the procedure you need to follow.
What to do if the startup screen does not appear when you press the
[Action] control
Even though the desktop appears when you press the [Action] control, there is still a
data error in memory and you have to perform a full reset (memory initialize). Before
you do, however, there is the chance that some of the data in memory can be recalled
and even transferred to a computer. Try recalling the data you need before performing
the procedure described on the next page to perform a full reset.
Important 
Do not use the ActiveSync backup function to back up data to a computer when you
suspect a data error. Doing so may also include the corrupted data that is causing your
problem, which means the problem will reappear when you restore the data. 
						

							36
Full Reset (Memory Initialize)
Full reset (memory initialize) deletes all data, and resets all unit parameters to their
initial defaults.
The following are conditions when you should perform a full reset.
•When you want to delete all memory data and return unit settings to their factory
defaults
•When you forget your password and need to clear it
•When a data error causes operational problems
•Appearance of the message: “A problem with memory contents has been found...”
Performing a Full Reset
Important
•The following procedure deletes all data in memory. Be sure that data is backed up or
that you no longer need it before performing the following procedure.
•If there is a CompactFlash card in the CASSIOPEIA’s slot, remove the card before
performing the full reset.
1. Make sure that unit power is turned on.
2. While holding down the [Power] button, use the stylus to hold down the RESET
button for about two seconds.
•This causes the following message to appear on the display screen.
“Proceeding with this operation initializes memory. Press [Action] to proceed or
[Record] to cancel.”
3. Press the [Action] control.
•This causes the following message to appear on the display screen.
“Proceeding with this operation deletes all data stored in memory. Press [Action]
to proceed or [Record] to cancel.”
4. Press the [Action] control again.
•This starts the full reset operation, which deletes all data in memory.
•Pressing the [Action] control displays the Startup screen. Perform steps 5 through 6
under “Initial Setup” on page 12 to set up the unit.
You can abort the full reset operation while the messages in steps 2 and 3 are on the
display by pressing the [Record] button. 
						

							37 Errors Following a Full Reset
Either of the following two conditions can cause errors to continue, even after you
perform a full reset.
•Hardware defect
•System problem caused by failure by you to correctly perform the reset procedure
before using the unit for the first time
If you suspect that the problem is being caused because you did not properly reset the
unit before using it for the first time, perform the procedure on page 41 of this manual.
This should correct the problem.
