Rechargeable Li-ion
battery (DSmobile
DS-940DW only)
• At the time of purchase, the rechargeable Li-ion
battery is slightly charged so that the operation
of the scanner can be verified; however, the
rechargeable Li-ion battery should be fully charged
via the USB port before the scanner is used.
• If the scanner will not be used for a long period
of time, store it in a location where it is not
exposed to high humidity or high temperatures
(temperatures between 59 °F/15 °C and
77 °F/25 °C and 40 to 60% humidity are
recommended). In order to maintain the efficiency
and life of the rechargeable Li-ion battery, charge it
at least every three months.
• If you notice anything unusual about the
rechargeable Li-ion battery the first time it is used,
for example overheating or rust, DO NOT continue
to use the battery. Contact your Brother dealer or
Brother customer service.
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 41~102 °F (5~39 °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.
Rechargeable Li-ion
battery characteristics
(DSmobile DS-940DW
only)
Understanding the properties of the rechargeable
Li-ion battery will allow you to optimize 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.
• We recommend charging the scanner every
three months to maintain the efficiency and life of
the rechargeable Li-ion battery.
• If you touch a part of the scanner while the
rechargeable Li-ion battery is charging, that part
of the scanner may feel warm. This is normal, and
the scanner may be used safely. If the scanner
becomes extremely hot, discontinue use.
