Installing And Replacing The Battery Pack - Casio DT-X400 Series User Manual

Installing and Replacing the Battery Pack

Your terminal uses two types of battery: a battery pack and a memory backup battery.
The battery pack is used to power normal operations and to store data, while the memory
backup battery provides the power required to maintain memory contents when the battery
pack power is unable to supply power for some reason. You can use the HA-S20BAT battery
pack with this terminal.
The backup battery is installed inside of the terminal.
This guide uses the following terms to refer to the batteries.
Battery Pack:
Backup Battery: Built-in battery for memory backup
When the battery pack power goes low, immediately charge it or replace it with a charged
battery pack.
The battery pack can be charged using the Multiple Battery Charger, Dual Battery Charger,
USB Cradle or Ethernet Cradle.
See the relevant sections in this guide for the respective options about how to use.
Important!
Always keep backup of all important data!
• The battery pack powers normal operation and also provides power required to
maintain memory contents, while the backup battery provides backup power to
maintain memory contents. Because of this, you should not remove the battery pack
if the backup battery is dead. Removing the battery pack while the backup battery is
dead causes data in the memory to be corrupted or lost. Note that once data is lost it
cannot be recovered. Always keep backup of all important data.
• The charge of a battery pack when you purchase it may be depleted due to testing at
the factory or natural discharge during shipment and storage. Be sure to charge the
battery pack before you use it.
• The life of a battery pack is limited, and charging a battery pack causes it to
gradually lose its ability to maintain the charge. If your battery pack seems to
require charging very frequently, it probably means it is time to purchase a new one.
• If a battery pack is used past the end of its service life, it may swell up in size. In such
a case, replace the battery pack with a new one.
• It takes approximately 4 hours with the main battery pack installed in the terminal
for the backup battery to be charged fully.
