Rechargeable Battery Pack Danger
Never try to take apart the battery pack or modify it in any way. The battery pack has built-in safety and protection mechanisms that ensure safe operation. Damaging these mechanisms creates the danger of fire, smoke emission, and explosion. Never allow the positive (+) and negative () terminals of the battery pack to become connected by metal. Never transport or store the battery pack together with a necklace, hairpins or other metal objects. Doing so can short the battery pack, which creates the danger of fire, overheating, and explosion. Never use or leave the battery pack next to open flame, near a stove, or any other area exposed to temperatures of 80C/170F or greater. Doing so creates the danger of fire and explosion. Never charge the battery pack near a stove, under direct sunlight, in an automobile parked in the sun, or any other area subject to high temperatures. High temperature can cause the battery packs safety mechanism to operate making it impossible to achieve a full charge. Heat can also cause an abnormal chemical reaction, which creates the danger of fire and explosion. Never pierce the battery pack with nails, hit it with a hammer, step on it, or throw it. Doing so can cause internal shorting, which creates the danger of fire and explosion. Never use a battery pack whose exterior is extremely damaged or deformed. Use of such a battery pack creates the danger of fire, overheating, and explosion. Never use the battery pack with any device other than this product. Doing so can cause abnormal current that damages the battery pack and creates the danger of fire. Keep a battery pack that is emitting a strange odor or leaking fluid away from open flame. Fluid leaking from the battery pack is highly flammable. It creates the danger of fire and explosion.

Danger

Never expose the battery pack to direct flame, do not throw it into fire, fresh water, or seawater. Doing so can damage the built in safety and protection mechanisms, and cause battery fluid to ignite, creating the danger of fire and explosion.

Warning

Should fluid from the battery pack ever accidentally get into your eyes, do not rub them. Rinse your eyes with tap water and then consult your physician immediately. If the battery pack does not achieve full charge after the normal charge time, stop charging. Continued charging creates the danger of fire, overheating, and explosion.

Batteries Warning

Never try to charge backup battery, take it apart, or allow it to become shorted. Do not apply solder to battery or expose it to heat, and never throw battery into fire or water. While the lithium battery is removed from the unit, take care to keep it in a place where there is no danger of it being accidentally swallowed. Be especially careful around young children. Keep batteries out of the reach of young children. If a battery is accidentally swallowed, consult a physician immediately. Should fluid from the battery accidentally get into your eyes, do not rub them. Rinse your eyes with water and then consult your physician immediately. When loading batteries, make sure their positive (+) and negative () poles are facing correctly.
Misuse of batteries can cause them to leak, which damages and corrodes the area around the battery and creates the danger of fire and personal injury. Be sure to observe the following precautions. Remove battery from the unit if you do not plan to use it for a long time. Use only battery types that are specified for this unit.

AC Adapter Warning

Never use a voltage that is different from that for which the AC adapter is rated. Also, do not plug the unit into a power outlet that is shared by other devices. Doing so creates the danger of fire and electrical shock. Never modify the power cord or excessively bend, twist, or pull it. Doing so creates the danger of fire and electrical shock. Do not allow the power cord to become damaged. Do not place heavy objects on the power cord or expose it to heat. A damaged power cord creates the danger of fire and electrical shock. Never touch the AC adapter while your hands are wet. Doing so creates the danger of electrical shock. Should the power cord ever become seriously damaged (internal wiring exposed or shorted), contact your original dealer or an authorized CASIO service provider to request servicing. Continued use of a seriously damaged power cord creates the danger of fire and electrical shock. Use only the AC adapter specified for this unit. Use of another type of AC adapter can damage the battery pack and create the danger of fire and personal injury.

Unplug the AC adapter from the wall outlet whenever leaving the unit unattended for long periods. At least once a year, unplug the AC adapter from the power outlet and clean the area around the prongs of the plug. Dust build up around the prongs can create the danger of fire. Be sure to unplug the AC adapter from the wall outlet before attempting to move the unit to another location. Be sure to grasp the AC adapter when unplugging it from a wall outlet. Pulling on the power cord can damage it, and create the danger of fire and electrical shock. Keep the power cord away from stoves and other sources of heat. Heat can melt the insulation of the power cord and create the danger of fire and electrical shock.
Display Screen Precautions Caution
Never apply strong pressure to the LCD screen or subject it to strong impact. Doing so can cause the LCD panel glass to crack or break. Should the LCD panel glass ever crack or break, never touch the liquid inside of the panel. LCD liquid can lead to skin irritation. Should LCD panel liquid ever get into your mouth, gargle with water and contact your physician immediately. Should LCD panel liquid ever get into your eyes or onto your skin, flush the exposed area with clean water for at least 15 minutes, and then contact your physician.

Operating Precautions

The CASSIOPEIA is a precision digital instrument. Incorrect operation and rough handling can cause data storage problems and other malfunction. Be sure to read the following precautions to ensure proper operation. Charge the battery pack as soon as possible when they start to become weak. Continued use while power is low can lead to loss of memory data.
Do not leave dead batteries in the CASSIOPEIA for long periods. Doing so can result in battery leakage, which can damage the CASSIOPEIA and cause malfunction.
Use the CASSIOPEIA under the conditions listed below. Temperature: 0C to 40C (32F to 104F) No condensation Conditions other than those above can cause malfunction. Avoid using the CASSIOPEIA in areas subjected to the following conditions. Static electricity Extreme heat or cold High humidity Sudden temperature changes Large amounts of dust If you drop the CASSIOPEIA and damage it, immediately turn off power and contact your original dealer or an authorized CASIO service provider. Never continue using a damaged unit. Never place heavy objects on top of the CASSIOPEIA.

Never try to take the CASSIOPEIA apart. Doing so can cause malfunction.
Never insert foreign objects into connectors, slots, or other openings.
Take care to avoid spilling water or drinks on the CASSIOPEIA.
Use only the stylus that comes with the CASSIOPEIA to press the reset button. Never use a pen, pencil, or other sharp writing implement. Doing so can scratch the touch screen and cause malfunction. Never use thinner, benzene, cosmetics, or other volatile agents to clean the exterior of the CASSIOPEIA. Use only a dry soft cloth or a soft cloth moistened with a weak solution of water and mild neutral detergent. Be sure to use the soft case to protect the display panel of your CASSIOPEIA while carrying it. Important The TFT color LCD is a product of the latest color LCD manufacturing technology. However, virtually all TFT color LCDs have a very small number of pixels (about 0.01% of the total number of pixels) that do not turn on or always remain turned on. This is normal and does not indicate malfunction. Playing back movies, digital camera images, and audio files consumes large amounts of power and may cause the CASSIOPEIA to become warm to the touch. This is normal and does not indicate malfunction. Inserting or removing a Storage card while the CASSIOPEIA is off causes power to turn on automatically. This is done so the CASSIOPEIA can detect the card slot status.

Warning Use only the AC adapter that is specified for this unit. Use of another type of AC adapter creates the danger of malfunction and bursting of battery. Important Power also will not turn on if the main battery loaded in the CASSIOPEIA is dead. Long term use of the AC adapter can cause it to become warm to the touch. This is normal and does not indicate malfunction. Be sure to unplug the AC adapter from the power outlet whenever you are not using it. The AC adapter is designed for indoor use only. It should not be used outdoors.

Infrared Communication

The infrared port of this unit can be used to exchange data with another CASSIOPEIA, or with another device equipped with infrared communication capabilities. Remember that the two infrared ports must be pointed directly at each other when performing communication. The distance between the two infrared ports must be less than 20 cm. See the Pocket PC Users Guide for full details on performing infrared communication. For infrared data communication with another device, the other device must conform with IrDA 1.2 standards, and it must specifically support infrared data communication with a CASSIOPEIA. Important Take care so either of the units does not move while infrared data communication are in progress. Infrared data communication may be impossible under strong sunlight or inverter type fluorescent lighting. Infrared data communication problems can be caused by the distance between the two ports, the angle between the two ports, outdoor sunlight, and low batteries. Dirt and dust on the infrared port surface can cause communication errors and other problems. Use a soft, dry cloth to wipe the port clean of dirt and dust.

Using a CompactFlash Card
Your CASSIOPEIA supports Type I and Type II CompactFlash Cards (3.3V). The following describes the types of CompactFlash card you can use with your CASSIOPEIA. Storage Card A storage card functions the same as the CASSIOPEIAs data storage memory. You can use a storage card to store the various files created by your CASSIOPEIA, and you can even install programs on a storage card. Data you store on a storage card is retained even when you remove the card from your CASSIOPEIA, which means a card can be used to port data between your CASSIOPEIA and computer or other device, or to keep backup copies of important data. Modem Card A modem card lets you connect to a telephone line (standard household modular jack, public telephone with modular jack, etc.) for modem data communications.
Wireless Modem Card With a wireless modem card, you can perform mobile data communication without a wire connection to a telephone circuit. Important Gently but firmly slide the card into place as far as it will go, but do not force it. Forcing a card can damage connectors. If you have problems inserting a card, pull it out and check to make sure it is oriented correctly. We strongly recommend that you store all unsaved data you are inputting or editing before performing this procedure. Sometimes, your CASSIOPEIA may not be able to detect a CompactFlash card. This is indicated when a program on the card does not start up normally. When this happens, remove the card, reinsert it, and then press the CASSIOPEIA reset button. Your CASSIOPEIA supports 3.3V CompactFlash cards only. 5.0V cards are not supported. Important Your CASSIOPEIA comes with a dummy card installed in its card slot. Be sure to remove the dummy card before trying to insert another card. An empty card slot creates the risk of damage to the slot when pressure is applied to the CASSIOPEIA. Always insert the dummy card when you are using the CASSIOPEIA without a card.
To install a CompactFlash card
1. Make sure your CASSIOPEIA is turned off. Press the power button to turn off power. 2. If there is a dummy card or another CF card in the slot, remove it.
3. Slide the card you want to use into the card slot. Make sure the top of the card is facing towards the top of the CASSIOPEIA unit. A card that is not oriented correctly will not slide all the way into the slot.

The Modem Adapter (JK-720MA) and CompactFlash type Modem Card (JK711MC56) make it possible to use your CASSIOPEIA to access the Internet over an analog dial-up connection. See the documentation that comes with the modem card for information about how to use it. Important Check to make sure that the battery pack is charged before using the modem adapter and modem card. Low battery power can cause sudden interruption of communication, unstable communication, and loss of data.

Software Applications

Software applications are available for purchase from Microsoft and third parties who support Windows CE. For details on commercially available software applications, contact your local retailer or visit the Microsoft Web site at http://www.microsoft.com. Your Pocket PC also comes with a CASSIOPEIA Applications CD-ROM that contains a number of useful applications. Note that you must install the applications you need from the CD-ROM before you can use them. See the documentation contained on the CD-ROM for details on using the software applications. Important Whenever purchasing software applications, always double-check to make sure that it is compatible with the CASSIOPEIA. Some applications written for a Palm-size PC (Windows CE 2.11) may not run on a Pocket PC. Contact the producer of the application for information about an upgrade to the Pocket PC version.

User Maintenance

Batteries
Your CASSIOPEIA 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 Users Guide and Pocket PC online help for more information about this properties. Important The following messages appear whenever battery power drops below a certain level. Main Battery Recharge the battery pack 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 owners manual.
