3.1 Charging the Device
Before first use, fully charge the recorder. Connect the device to a computer's USB port or a USB wall adapter using the provided USB cable. The charging indicator light will show the charging status. A full charge typically takes approximately 10 hours for the initial charge, and around 2-3 hours for subsequent charges. Ensure the device is fully charged before use to avoid recognition issues with your computer.
The recorder offers up to 18 hours of continuous recording on a full charge.
3.2 Connecting to a Computer
To access recorded files or configure settings, connect the recorder to your computer using the supplied USB cable. The device will appear as a removable disk. You can then drag and drop files to transfer them to your computer. Ensure the device is fully charged for proper recognition by your computer.

4. Operating Instructions
4.1 Basic Recording
To start recording, simply slide the power switch to the 'ON' position. The device will begin recording automatically. To stop recording and save the file, slide the power switch to the 'OFF' position. The recorder will automatically save the current recording before powering down.
One-click recording: simply slide the switch to ON to start and OFF to save and stop.
4.2 Voice Activated Recording (VOR)
The recorder features a Voice Activated Recording (VOR) mode. In this mode, the device will only record when it detects sound, conserving memory and battery life by skipping silent periods. This feature is enhanced by a built-in DSP intelligent noise reduction chip, which helps to capture clearer audio by minimizing background noise.
The recorder utilizes DSP intelligent noise reduction for clear voice capture.
The Automatic Gain Control (AGC) algorithm compensates for gain, making recordings more realistic.
4.3 Saving Recordings
Recordings are automatically saved as WAV files. When the battery is low, the recorder will automatically save the current file and then power off to prevent data loss.
The recorder's compact and portable design allows for discreet placement, such as on a wall clock.
4.4 Playing Back Recordings
To play back recordings, connect the device to your computer. Navigate to the removable disk, locate the WAV files, and open them with your preferred audio player. The device records in 5-hour blocks, creating new files automatically after each block.
Users can view or play recording files by connecting the computer and the recorder without complicated operations.
