Tips on using the
rechargeable Li-ion battery
(DSmobile DS-940DW
only)
• Charge the rechargeable Li-ion battery before use.
Do not use the scanner until the rechargeable
Li-ion battery has been fully charged.
• The rechargeable Li-ion battery charging can
take place in 5 °C - 39 °C environments. If the
surrounding temperature is out of this range, the
rechargeable Li-ion battery will not be charged,
and the battery indicator will remain lit.
• If the scanner is used when both the rechargeable
Li-ion battery is installed and the scanner is
connected to your computer, charging may stop even
if the rechargeable Li-ion battery has not been fully
charged.

Understanding the properties of the rechargeable
Li-ion battery will allow you to optimise its usage.
• Using or storing the rechargeable Li-ion battery
in a location exposed to high or low temperatures
may accelerate its deterioration. In particular,
using a rechargeable Li-ion battery with a high
charge (90% or more) in a location exposed to
high temperatures will considerably accelerate
battery deterioration.
• Using the scanner while the rechargeable Li-ion
battery is installed and charging may accelerate
the battery's deterioration.
• If the rechargeable Li-ion battery will not be used
for a long period of time, we recommend charging
it every three months.
• While the rechargeable Li-ion battery is charging,
the scanner may become warm. This is normal,
and the scanner may be used safely. If the
scanner becomes extremely hot, stop using it.
