8 characters. The first 4 are user selected (if nothing is selected, the generic word “TEST” is used). The
last 4 characters are the file counter “#000” followed by extension .TXT.
In this manner, the generic file name (if user selects nothing in the “File name” field) is “TEST#001.TXT”

“abcd#001.TXT” thru “abcd#999.TXT”. The number of files allowed per single recording is 999. The
recording will stop, and the unit will shut itself down once this number is reached.
