This is true regardless of whether the AC power is being supplied through the AC power jack or the
power terminals.
•External AC power also charges the battery pack attached to the CASSIOPEIA. See"Charging a
Battery Pack on the CASSIOPEIA" on the later page for more information.

— 12 —
Main Battery and Backup Battery
Your CASSIOPEIA uses two types of batteries for power:a rechargeable user-replaceable rechargeable
battery pack for the main battery, and a button type lithium battery for memory backup.
•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 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

contents...”
Important
Be sure to observe the following important battery handling precautions. Failure to do so can cause
batteries to leak, resulting in damage to surrounding items and create the danger of fire and electrical
shock.

— 13 —
•Use only the types of batteries specified for use with this unit.
•Charge the battery pack in an area where the temperature is between 10˚C (50˚F) and 35˚C (95˚F).
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 CASSIOPEIA. Be sure to recharge the battery pack at least once every three months,
regardless of how much you use the CASSIOPEIA during that time.
•A battery pack that loses power too quickly after it is charged is probably near the end of its service
life. In such a case, you have to purchase a new battery pack.
Charging the Battery Pack on the CASSIOPEIA
1. Attach the rechargeable battery pack to your CASSIOPEIA.
2. Use one of the three following procedures to charge the battery pack.
Charge using the AC adapter
Charge using the AC adapter/charger
Charge using the cradle
•Charging starts automatically.
•The charge indicator on the CASSIOPEIA lights amber while charging is in progress, and changes
to green when charging is complete.
•An M Type battery pack takes about five hours to reach a full charge when the CASSIOPEIA is
turned off while charging.
•The time required to attain a full charge is greatly affected by ambient temperature and the type of
operations you perform on the CASSIOPEIA while charging is taking place.
•You can normally operate the CASSIOPEIA while charging is taking place.
However, you will not be able to perform any operation when setting up the CASSIOPEIA the first
time after you purchased it, or while charging a new battery pack for the first time.
Using a CompactFlash Card
Your CASSIOPEIA supports Type I and Type II CompactFlash cards (3.3V).
Important
•The card slot cover will not close when certain types of cards are in the slot. When using such a
card, detach the strap from the card slot cover, remove the card slot cover from the CASSIOPEIA,
and keep the cover in a safe place so you can replace it when you remove the card.
•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. Cards that can operate on 5.0V only
are not supported.

Infrared Communications
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 communications.The distance between the two infrared
ports must be less than 30 cm.
See the Pocket PC User's Guide for full details on performing infrared communications.
For infrared data communications with another device, the other device must conform with IrDA 1.1
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 communications are in progress.
•Infrared data communications 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 communications errors and other problems.
Use a soft, dry cloth to wipe the port clean of dirt and dust.

battery pack (JK-210RBM) takes about five hours to reach a full charge with normal (non-rapid)
charging when the CASSIOPEIA is being used to perform an operation that consumes a large
amount of power.
•Avoid using the AC adapter/charger to power the CASSIOPEIA while rapid charge is in progress.
Connecting the AC adapter/charger to the CASSIOPEIA can cause rapid charging to switch
automatically to normal charging.
