If there are no trigger pulls during the “scanner power time-out timer” interval, the scanner goes into power down mode. Whenever the trigger is enabled, the “scanner power time-out timer” is reset. If the scanner is placed in the 2020-5B cradle and the battery is in the process of being charged, the scanner will not go into power down mode.
