5.3. Setting Date and Time

The device automatically names files by date and time. To ensure accuracy, connect the device to a computer. The date and time settings can typically be configured through a text file on the device's storage or via specific software if provided by the manufacturer. Refer to the detailed instructions in the included user manual for precise steps.

6. Operating Instructions

6.2. Voice Activated Recording (AVR)

The Voice Activated Recording (AVR) function allows the device to record only when sound is detected, pausing during silence to conserve memory and battery.

2. Once AVR is enabled, slide the Record Button to ON. The device will intelligently start and stop recording based on sound levels.
3. Note: Voice activation is not recommended for important occasions where continuous recording is critical, as very low sounds might not trigger recording.

Then, use the USB-C to USB-A adapter (if needed) and the USB-A to USB-C cable to connect the recorder to your phone. You can then access and play files using a file manager app.

8. Troubleshooting

• Device not recognized by computer: Ensure the USB-C cable is securely connected to both the recorder and the computer. Try a different USB port or a different USB-C cable. Restart your computer and the recorder.
