How is the recorder controlled in the field?

The recorder can be controlled using a two-way long-range radio frequency remote controller to manage its operations and status.

How does the remote button work?

A long press (more than five seconds) starts or stops recording. A short press checks status: green LED blinking indicates recording, red LED blinking indicates stand-by mode.

How are recordings stored and secured?

Audio is stored on a detachable micro SD card in non-compressed linear PCM format and can be encrypted using AES 256.
