When being not used, the scanner can be also set on the cradle for battery
charging.
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.
MS840 features 2 memory mode settings: Batch Mode and Inventory Mode
Note: The 4 KB of memory buffer in the scanner can hold as many as 256 scans
based on EAN-13 barcodes. Data will be cleared out once the scanner is not
powered!
