Setup

1. Charging the Device

Before first use, fully charge the recorder. Connect the supplied USB-C cable to the device's USB-C port and the other end to a USB power adapter (not included) or a computer's USB port. The battery indicator on the screen will show charging status. A full charge provides approximately 12 hours of general use, with up to 45 hours of continuous recording time depending on settings.

2. Initial Power On and Basic Settings

To power on, slide the REC/SAVE switch to the 'SAVE' position or press and hold the power button (if available, otherwise assume it powers on by sliding the switch). Upon first use, you may need to set the language, date, and time. Navigate through the menu using the control buttons to access 'Settings' and adjust these parameters.

3. Setting Password Protection

For enhanced security, you can set a password to protect your recordings. Access the 'Settings' menu, locate the 'Password' option, and follow the on-screen prompts to set your desired passcode. This prevents unauthorized access to your files on the device or when connected to a computer.

Operating Instructions

1. Basic Recording

To start recording, simply slide the REC/SAVE switch to the 'REC' position. The device will begin recording immediately. To stop recording and save the file, slide the switch back to the 'SAVE' position. The recording will be saved automatically to the internal 32GB memory.

2. Recording Formats and Quality

The V619 supports both MP3 and WAV recording formats. You can select your preferred format and recording quality (bitrate) through the device's menu. Higher bitrates (e.g., 1536Kbps WAV) offer superior audio fidelity but consume more storage space. Lower bitrates (e.g., 32Kbps MP3) save space but may reduce audio quality. The device can store over 1000 hours of recording files.

3. Voice Activated Recording (AVR)

The Voice Activated Recording (AVR) function allows the recorder to automatically start recording when sound is detected and pause when silence occurs. This feature helps conserve memory and battery life by only recording when necessary. You can adjust the AVR sensitivity level in the settings menu.

4. Timed Recording

Set the recorder to start and stop recording at specific times using the Timed Recording feature. This is useful for scheduling recordings of lectures or meetings. Access this option in the recording settings to configure start time, end time, and recording cycle (e.g., single, everyday, working day).

5. Playback and A-B Repeat

To play back recordings, navigate to the 'Recordings Library' from the main menu. Select the desired file and press the play/pause button. The A-B repeat function allows you to loop a specific section of an audio file, which is ideal for studying or transcribing important phrases.

6. Connecting External Microphone/Line-in

The V619 supports external microphones and line-in audio sources via its 3.5mm audio jack. This provides flexibility for different recording scenarios, such as connecting a lavalier microphone for interviews or directly recording from an audio output device.

7. Transferring Files to Computer

Connect the recorder to your computer using the supplied USB-C cable. The device will appear as a removable storage drive. You can then easily drag and drop your recorded audio files to your computer for backup, editing, or sharing.
