Product Safety Guide

DO NOT attempt to service the scanner yourself 

because disassembling the scanner may expose you 

to dangerous voltage points and other risks and may 

void your warranty. Refer all servicing to a Brother 

Authorized Service Center. For the location of your

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.

•  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.
