The audio file can be saved on the HDD or on the USB device.

In Figure 4-173, when it is HDD mode, the newly added audio file can be saved on
the HDD automatically. You do not need to connect to the USB device if you want to
use it the next time.

In Figure 4-173, when it is USB mode, after you imported, you need to connect the
USB device all the time; otherwise, the audio link function may fail. So, if you want to
use the audio trigger function, please make sure the audio file is on the UBS device
and the USB device has connected to the DVR before the DVR boots up. You need to
make sure the USB device connection is always there if you want to manage and use
the audio file function.

If there is a USB device (containing the audio file) and the HDD (containing the audio
file) at the same time, the HDD mode has higher priority. That is to say, DVR uses the
audio file from the HDD.
