Pressing this button also turns on power. Power can be turned off only by pressing the power button.
DESKTOP COMPUTER SYSTEM CONFIGURATION The computer configuration described below is required to support the installer and the software applications contained on the Microsoft CD-ROM supplied with the CASSIOPEIA. • Microsoft Windows NT Workstation 4.0 or Windows 95 (U.S. version) • Desktop computer with a 486/33DX or higher processor (Pentium P90 recommended) • 12 MB of memory for Windows NT Workstation 4.
Important • Should the display lock up or go blank at this time, first perform the full reset (page 12). If this does not correct the problem, remove the main batteries from the CASSIOPEIA and then remove the back-up battery. Wait for about five minutes, and then perform this procedure again, starting from step 1. Be sure that the positive (+) and negative (–) poles of the batteries are facing correctly when you reload them into the CASSIOPEIA.
REPLACING BATTERIES The CASSIOPEIA has a dual power supply that consists of main batteries and a backup battery. Be sure to load the main batteries and a back-up battery before using the CASSIOPEIA for the first time after purchasing it. Also, replace batteries as soon as possible after they start to get weak. Important! • Never remove both the main batteries and the backup battery from the CASSIOPEIA at the same time. If you do, data stored in memory can be corrupted or lost entirely.
5. Reattach the battery holder to the CASSIOPEIA. • The battery holder will emit a click and the battery holder release will automatically lock when the battery holder is securely in place. To replace the backup battery 1. Make sure the CASSIOPEIA is turned off. • If the CASSIOPEIA is on, press the power switch to turn it off. 2. Close the CASSIOPEIA and turn it over. 3. While pressing the release A with the stylus, slide the backup battery cover from the CASSIOPEIA. 4. Remove the old battery. 5.
RESET You should reset the CASSIOPEIA whenever it stops working or whenever some other operational problem has caused it to malfunction. To reset the CASSIOPEIA 1. Press the RESET button with the stylus. • This automatically turns off CASSIOPEIA power. 2. Press the power switch to turn on power and start the reset process. • What happens next depends on memory status. Case A: Memory Contents Not Corrupted In this case, the display changes in the sequence shown below.
FULL RESET Perform the full reset when you want to clear all memory contents and settings because memory contents are corrupted, because you have forgotten the security code, or for any other reason. Important The following procedure deletes all data in memory. Be sure to save any important data contents you may need later to a computer disk or other medium. Always keep separate back-up copies of important data. To perform a full reset 1.
CONNECTING TO A DESKTOP COMPUTER Use the following procedure to connect the CASSIOPEIA to a desktop computer. Note that exchanging data with a desktop computer requires Microsoft Windows CE Services, which is on the Microsoft CD-ROM that is included with the CASSIOPEIA. Requirements RS-232C cable (supplied with CASSIOPEIA) To connect to a desktop computer 1. Open the RS-232C connector cover on the side of the CASSIOPEIA. 2. Slide the cover into the CASSIOPEIA case as shown below. 3.
REPLACING THE PC CARD The CASSIOPEIA comes equipped with a PC card slot that supports memory, modem and other PC cards*. * Use only PC cards that are compatible with the CASSIOPEIA. Important • Be sure to keep the dummy card that comes with the CASSIOPEIA inserted in the card slot whenever you are not using a PC card. • Be sure to save any unsaved input or edited data before replacing the PC card. • Never remove the PC card from the CASSIOPEIA while a PC card operation is in progress.
REPLACING THE COMPACTFLASH CARD The CASSIOPEIA comes equipped with a card slot that supports CompactFlash cards. Important • If the card stops part way into the slot, do not try to force it. Doing so can damage the card or the CASSIOPEIA. Remove the card, make sure it is oriented correctly, and then try inserting it again. • Be sure to save any unsaved input or edited data before replacing the CompactFlash card. To replace the CompactFlash card 1. Make sure that CASSIOPEIA power is turned off. 2.
CONNECTING TO EXTERNAL EQUIPMENT You can connect external equipment to the data communication connector. You can also use special software to set up the CASSIOPEIA to exchange image data with a CASIO digital camera. See the documentation that comes with the software for details. Requirements Optional data communication cable (SB-62) To connect external equipment 1. Make sure the external equipment and CASSIOPEIA are both turned off. 2.
MEMORY BACKUP / RESTORE Make the backup copy by Windows CE Services to your PC before repairing PA-2500U, and restore the data from PC to user’s PA-2500U after repairing. For the details of Backup/Restore, refer to the operation manual of Windows CE Services. Notes: 1* Backup program of Windows CE Services back up only files and databases. Setup data including Owner, World Clock and so on, can not be backed up to PC. 2* Use AC adaptor when making backup copy and restoring. Backup 1.
6. Click “Full: back up all data” and “Back Up Now”. 7. Confirm the file name of bakup copy and then click “OK”. Backup starts.
Restore Execute Restore after repairing. 1. Turn on the user’s PA-2500U and then Welcome wizard appears. 2. Execute touch panel calibration and then skip other setups after calibration. 3. Connect repaired PA-2500U to your PC with RS-232C cable. 4. Start Windows CE Services on your PC. 5. Click “Restore” and confirm the file name backed up. Then click “OK”. 6. Click “Restore”.
7. Restoring starts. 8. Click “OK”.
