1. Select MENU > Recording > Rec Beeper/Tally .
Following options are available:
Rec Start Beeper The camera gives an acoustic indication for start of recording.
Rec Stop Beeper The camera gives an acoustic indication for stop of recording.
Media Full Beeper The camera gives an acoustic indication for stopping recording due
to full card. For better distinction, a different sound pattern than the
start/stop beeper is used.

16.7 File Naming Scheme
The ALEXA Mini LF automatically names files as they are created on the recording media. While it is
possible to change the file names later on a computer, it is not recommended, as the ALEXA naming
scheme has been developed to minimize the risk of duplicate file names.
A typical clip name would look like this: A004C010_190325_RN9O.mxf
The clip name consists of eight parts:
Camera Index (A) One character, A-Z. User assignable, should match the camera unit.
For example, the camera index A can be assigned to the A camera,
and B to the B camera etc.
Reel Counter (004) 3 characters, 001-999. Automatically assigned to each recording me-
dia, automatically advanced by one for each new media. The user can
change the counter for the next reel. This should only be done under
special circumstances, such as after changing the camera body in the
middle of a shoot.
Clip Index (C) One character, fixed to C. Main use is to separate the reel counter
from the clip counter.
Clip Counter (010) 3 characters, 001-999. Automatically advances each time a clip is
recorded.
Date (190325) Current date, in order YYMMDD, as set in Menu > System > System
time + date, separated from the other naming components by under-
scores.
Camera ID Prefix (R) One character, A-Z. Typical use would be setting one camera's ID pre-
fix to L (for left) and the other's to R (for right) for 3D applications.
Camera ID (N9O) The camera serial number encoded in 3 letters Base36 (0-9, A-Z).
N9O translates into decimal serial number 30156.
File name Extension (.mxf) All files are written as .mxf files.
The reel counter should be set to 001 at the beginning of a shoot. The camera will then automatically
advance the reel number each time a new recording medium is loaded into the camera, formatted and
recorded on. If a previously recorded medium is reloaded in the camera (comparable to a short end of a
film roll), it will keep its reel number and the camera will continue the reel count. If the medium is loaded
in another camera, it keeps its name, but a new folder with the according camera ID and reel number
is created in the root folder of the medium. It is possible, but usually not necessary, to manually change
the next reel number in the project menu.
