Charging the Battery in Your Motorola LS4278
You should fully charge the LS4278 scanner battery before using the scanner for the first time. To charge the scanner battery, pace the Motorola LS4278 in the cradle, ensuring that the metal contacts on the bottom of the scanner touch the contacts on the cradle. The battery begins charging when the LED indicators starts flashing green. A complete charge of a fully discharged battery can take up to three hours using external power and up to five hours using non-external cable power.
NOTE: To avoid battery temperature fault, always charge the battery in the scanner within the recommended temperature of 32° to 104° F (1° to 40° C) nominal, 41° to 95° (5° to 35°) ideal.
