Power Supply - Casio DT-930M50E User Manual

Power Supply

The Handheld Terminal has both operating power supply provided by either two
AA (LR6)-size alkaline batteries or lithium-ion battery pack, and memory backup
power supply provided by lithium battery. In this manual, the words "main
battery"
refer to both alkaline batteries and the lithium-ion battery pack, unless
otherwise
noted.
Low main battery power is indicated when the low voltage message appears on the LCD
screen. Replace the main battery or charge the battery pack as soon as possible after the
low voltage message appears.
[Caution]
■ For Important Data
· Never remove both the main battery and backup battery at the same
time. Doing so causes all program settings and data in Handheld
Terminal memory to be lost or changed. Data cannot be recovered
once it is lost or corrupted. Be sure to make back-up copies of all
important data. One way to do this is to use one of the optional cradles
to transfer data to a computer.
Important!
power is turned ON. Doing so can cause data in Handheld Terminal
memory to be lost. Before you remove the battery, be sure to turn the
Handheld Terminal OFF.
· Use only two AA (LR6)-size alkaline batteries or the dedicated lithium-
ion battery pack.
· The lithium-ion battery pack discharges naturally during its
transportation from the factory to an end-user. Be sure to charge the
battery pack before you use it for the first time.
· Never allow the terminals of the lithium-ion battery to become shorted.
Doing so creates the danger of malfunction. Be sure to keep the
battery pack in its case when transporting or storing it.
· Repeat charging of the lithium-ion battery pack gradually shortens its
ability to recharge. If you find that a fully charged battery pack
provides only little operation time, it probably means you need a new
battery pack.
· Whenever you do not plan to use the Handheld Terminal for a long
time, load two new alkaline batteries or a fully charged battery pack
into the Handheld Terminal to protect against power failure during non-
use. Also, load new batteries or a fully charged battery pack before
using the Handheld Terminal after a long period of non-use.
· If the battery pack has been left over unused for a long period of time,
the capacity remained decreases due to spontaneous discharge or
chemical decomposition by the battery pack itself. If the battery pack
fails to hold its operating duration after it has been fully charged,
