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 Liion 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.
