A full charge typically takes approximately 1.5 hours. The device will indicate charging status (e.g., an LED indicator).
3.2. Initial Power On
Locate the power switch or button on the device. Slide or press it to the 'ON' position to power on the recorder. The device may display a startup indicator or light up.
4. Operating Instructions

4.2. Voice-Activated Recording (VAR)

To activate VAR: Consult your device's specific controls. Typically, there is a dedicated switch or a menu option to enable or disable voice activation. When enabled, the recorder will automatically start recording when sound levels exceed a certain threshold (e.g., >45dB) and pause when sound levels drop below it (e.g., <45dB).
