All recorded files are protected by a digital signature. Use a special utility to prove the authenticity of files and
check for any editing.
The files can also be protected by a user password. While playing back these files there will be only 'white
noise'. Use a special utility to decode it.
The above utilities can be downloaded from the Telesystems website.
Preparing microSD Card
MicroSD card which is in the delivery set, doesn't require any preliminary preparation. It has a configuration
text file CONFIG.INI containing Recorder's settings. After inserting memory card into the Recorder, there will
be a short flash of the red LED, and the Recorder will write CONFIG_CARD24.INI configuration file of the
operation modes onto the card. After that, the card can be removed and the configuration file can be edited
in accordance with the settings needed.
The memory card used in the Recorder must be formatted in accordance with FAT 16, FAT 32 or exFAT file
system - for memory cards with a capacity of more than 32 GB.
After inserting a formatted memory card into the Recorder, there will be a short flash of the red LED, and the
Recorder will write CONFIG_CARD24.INI configuration file of the operation modes onto the card.
After that, the card can be removed and the configuration file can be edited in accordance with the settings
needed. For more details see the section 'Changing Recorder's Settings Using Configuration File'.
If a new memory card needs to be used, first make sure that the file system installed on the card is FAT32 or
ExFat. Next, install a new microSD into the Recorder. The Recorder will generate a configuration file.
