When being not used, the scanner can be also set on the cradle for battery

Memory Buffer Setting 
The collected data can be sent back to a host computer one by one via the WPAN 
connection as the scanner is set to the Batch Mode, or can be stored in the flash 
memory of the scanner being set to the Inventory Mode. 
By default, the Batch Mode is enabled for use when the scanner is out of range. 
Upon reading a barcode successfully within range, the scanner responds with one 
short beep (high tone) and its LED indicator becomes solid green and goes off 
quickly. However, the host computer may not receive the data immediately if 
getting out of range. With the 4 KB transmit buffer, the scanner can ignore the 
transmission status and keep on reading barcodes until the buffer is full. 
When the Batch Mode is enabled and the scanner is out of range, the scanner will 
respond with two short beeps, high-low tone, upon reading a barcode successfully. 
When the memory buffer is full, the scanner will respond with one long beep (low 
tone) and its LED indicator will become solid red and go off quickly. You are 
advised to get back to range.
