By default the naming sequence for recordings is a combination of the device name (e.g. SHOGUN, BLADE etc) and the scene, shot, take. You can change this to suit the naming convention for your project.
Press the Menu icon from the home page of the device and then press "File Naming".
To change the unit name tap the arrow under UNIT/MEDIA NAME, use the left and right arrows to select a letter and the up and down arrows to change its value.
To modify the scene and shot number under CONFIGURE FILE NAME, select plus or minus next to scene or shot (up to 999). The number you choose will then be shown in the file name at the top of the screen during recording. The take number is automatically increased with each take.
