3. RESET OPERATION

Batteries

Your Pocket PC is powered by a dual power supply that consists of a main battery (rechargeable battery pack) and a backup battery (CR2032 lithium battery).

• We recommend that you use the Power Properties to keep informed about the current levels of your main and backup batteries. See the separate Pocket PC User’s Guide and Pocket PC online help for more information about these properties.

Important

The following messages appear whenever the battery power drops below a certain level.

Main battery

Recharge the battery pack (L36880-N9001-A106) as soon as possible after the following message appears.

“Main Batteries Very Low To prevent possible data loss, replace or recharge your main batteries according to the owner’s manual.”

Backup battery

Replace the backup battery as soon as possible after the following message appears.

“Backup Battery Very Low To prevent possible data loss, replace or recharge your backup batteries according to the owner’s manual.”

If the unit switches off due to insufficient power , the following warning message appears on the display the next time you switch on the unit.

“Warning Due to high current demand by the hardware, the system powered down in order to protect memory contents...”

If the unit switches off due to a sudden power drain by a CompactFlash card, the following warning message appears on the display the next time you switch on the unit.

“Warning Due to high current demand by the card, the system powered down in order to protect memory contents...”

Important

Make sure that you observe the following important battery handling precautions. Failure to do so can cause batteries to leak. This can result in damage to surrounding items and may result in fire and electrical shock.

• Always make sure that the positive (+) and negative (–) poles of the batteries are aligned correctly.

• Use only the types of batteries specified for use with this unit (L36880-N9001-A106).

• Charge the battery pack in an area where the temperature is between 10 °C and 35 °C. Charging in areas

that are very cold or exposed to direct sunlight can cause deterioration and leaking of the battery pack.

• To avoid deterioration and leaking, the battery pack is designed to discharge even when you do not use the Pocket PC. Make sure that you recharge the battery pack at least once every three months, regardless of how much you use the Pocket PC during that time.

• A battery pack that loses power too quickly after it is charged is probably near the end of its service life. If this is the case, you must purchase a new battery pack.

Page 10

Replacing the main battery

1. Make sure that your Pocket PC is turned off.

2. Turn the Pocket PC over.

3. The main battery lock to the FREE position.

4. Insert a new battery pack into the battery compartment.

5. The main battery lock to the LOCK position.

Replacing the backup battery

Important

• Never remove the main battery and backup battery from the Pocket PC at the same time. Doing so causes all data stored in memory to be deleted.

• Should the main battery and the backup battery both require replacement, always replace the main battery first.

• Make sure that you replace the backup battery as soon as possible whenever the following message appears on the display:

“Backup Battery Very Low T o prevent possible data loss, replace or recharge your backup battery according to the owner’s manual”.

1. Make sure that your Pocket PC is turned off.

2. Turn the Pocket PC over.

3. Insert the tip of the stylus under the backup tray, and pull the tray out.

4. Remove the old battery.

5. After wiping both sides of a new lithium battery (CR2032) with a dry cloth, place it into the backup battery tray with the positive side facing up.

6. Replace the backup tray holder into the Pocket PC.

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, however, is retained, as are all settings. 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 a reset is required.

• The unit does not respond when you tap the screen or press a button.

• The icon that indicates that a procedure is in progress remains on the display for a long time.

Important

We strongly recommend that you back up the data in Pocket PC memory, if possible, before performing a reset. Normally the reboot-type reset does not delete data in Pocket PC memory. If corrupted data is discovered, however, all data stored in memory will be deleted. No matter what type of computing device you are using, it is always a good idea to back up memory contents periodically to protect against unexpected loss of data.

Page 11

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

• Today screen

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 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 cuttently 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. The remainder of this procedure identical to the initial setup described in the Quick Start Guide. Perform the steps of the initial setup procedure.

• 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 following 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.

Full reset (memory initialize)

Full reset (memory initialize) deletes all data, and resets all unit parameters to their initial defaults. You should perform a full reset under the following conditions.

• 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...”

— 8 —

Page 12

Performing a full reset

Important

• The following procedure deletes all data in memory. Ensure that data is backed up or that you no longer need it before performing the following procedure.

• If there is a CompactFlash card and SD card/MultiMediaCard in the Pocket PC’s slot, remove the card before performing the full reset.

1. Make sure that the unit’s 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. The remainder of this procedure is identical to the

initial setup described in the Quick Start Guide. Perform the steps of the initial setup procedure.

You can abort the full reset operation while the messages in steps 2 and 3 are on the display by pressing the [Record] button.

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 because you failed to perform the reset procedure correctly before using the unit

for the first time
