Power Requirements
Your CASSIOPEIA can be powered using either a battery or external AC power.
Battery Power
Two types of batteries are used for power: a main battery and a memory backup battery.
The main battery is a rechargeable user-replaceable battery pack. The memory backup battery is a
button type lithium battery that provides the power required to retain memory contents. Note that the
memory backup battery is not user-replaceable.
• See "Main Battery and Backup Battery"on the next page for more information about the main
battery and memory backup battery.
External AC Power
Connecting the AC adapter or AC adapter/charger to the AC adapter jack on the left side of the
CASSIOPEIA unit provides power in place of the main battery. AC power is also supplied through the
power terminals on the bottom of the CASSIOPEIA whenever it is placed on the cradle.
• The CASSIOPEIA can operate under AC power only if its rechargeable battery pack is attached.
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.
