3. Setup

3.1. Initial Charge

Before first use, fully charge the device. Connect the recorder to a USB power source (e.g., computer USB port, wall adapter) using the provided USB cable. The indicator light will show charging status.

3.2. Time Synchronization and Advanced Settings (RECSET.txt)

The device's time and advanced recording parameters can be configured by modifying the RECSET.txt file located on the recorder when connected to a computer. Ensure the recorder is switched to OFF before connecting to a computer.

To access and modify settings:

1. Switch the recorder to the OFF position.
2. Connect the recorder to your computer using the USB cable. It will appear as a removable disk (e.g., "USB DISK").
3. Open the "USB DISK" drive and locate the RECSET.txt file.
4. Open RECSET.txt with a plain text editor (e.g., Notepad on Windows, TextEdit on Mac).
5. Modify the desired parameters as described below.
6. Save the RECSET.txt file and safely eject the recorder from your computer.

Parameters in RECSET.txt:

• Time:YYYYMMDDHHMMSS
  This sets the device's internal clock. Modify the numbers to match your current date and time. For example, Time:20231027143000 for October 27, 2023, 2:30 PM.
• Gain:X (Adjust recording sensitivity 0-7, Advice:5)
  Adjusts microphone sensitivity. A higher number (up to 7) increases sensitivity, capturing quieter sounds but potentially more background noise. A lower number reduces sensitivity. A setting of 5 is recommended for general use to balance sound capture and ambient noise reduction.
• Vor:X (0 means voice activated mode is off, 1-10 means is on, Advice:0)
  Controls Voice Activated Recording (VOR). 0 disables VOR. Numbers 1-10 enable VOR, with lower numbers requiring less sound to activate recording. For example, 1 is very sensitive, 10 is less sensitive. A setting of 1 or 2 is recommended if VOR is desired.
• Bit:X (0-32kbps, 1-64kbps, 2-128kbps, 3-192kbps, 4-384kbps, Advice:3)
  Sets the recording bitrate (audio quality). Higher bitrates result in clearer sound but larger file sizes and shorter battery life. Lower bitrates save space and battery but reduce audio quality. 3 (192kbps) is generally recommended for good balance.
• PART:X (Recording file division, Adjustment 0-240 minutes, 0 meaning 8 hours, Advice:0)
  Divides recordings into segments. 0 means recordings are saved in 8-hour segments. A number from 1-240 sets the segment duration in minutes. For example, PART:60 saves recordings in 60-minute segments. No change is recommended for continuous recording.

3.3. Synchronizing Time (Windows Only)

For Windows users, a dedicated tool is provided to synchronize the recorder's time with your computer's time automatically.

1. Ensure the recorder is switched to OFF and connected to your computer.
2. Open the "USB DISK" drive and navigate to the Settime folder.
3. Run the SetDigitRecorderTm.exe application.
4. Click the "Settime" button in the application to synchronize the time.

5. Advanced Features

Advanced settings such as Voice Activated Recording (VOR) sensitivity, recording quality (bitrate), and segment recording duration can be adjusted via the RECSET.txt file as described in the Setup section. Remember to save changes to RECSET.txt and safely eject the device after modification.

5.1. Voice Activated Recording (VOR)

When VOR is enabled (Vor:1-10 in RECSET.txt), the recorder will automatically start recording when it detects sound above a certain decibel level and pause when there is no sound. This feature helps conserve battery life and storage space by eliminating silent periods in your recordings.

5.2. Recording Quality (Bitrate)

Adjusting the Bit parameter in RECSET.txt allows you to choose between different audio quality levels. A higher bitrate (e.g., 384kbps) provides superior sound clarity but consumes more storage and battery. A lower bitrate (e.g., 32kbps) is suitable for longer recordings where absolute fidelity is not critical.

5.3. Segment Recording

The PART parameter in RECSET.txt allows you to divide long recordings into smaller, more manageable files. This can be useful for organizing recordings or for platforms that have file size limits. Setting PART:0 will save recordings in 8-hour segments, while setting a value like PART:60 will create new files every 60 minutes.

6. Connecting to PC/Phone

The Vandlion V15 can be connected to a computer (Windows/Mac) or an Android phone to manage your recorded files.

6.1. Connecting to a Computer (Windows/Mac)

1. Ensure the recorder is switched to the OFF position.
2. Connect the recorder to your computer using the provided USB cable.
3. The device will be recognized as a removable disk (e.g., "USB DISK").
4. Open the drive to access your recorded files, which are typically in .WAV format, located in the RECORD folder.
5. You can copy, move, delete, or rename files as needed.
6. After managing files, safely eject the "USB DISK" before disconnecting the recorder.

6.2. Connecting to an Android Phone

To connect to an Android phone, use the provided OTG adapter:

1. Ensure the recorder is switched to the OFF position.
2. Connect the recorder to the OTG adapter, then connect the adapter to your Android phone.
3. Your phone should recognize the recorder as an external USB device. You may need to enable OTG functionality in your phone's settings if it doesn't automatically detect it.
4. Use your phone's file manager to access and manage the recorded files.

7.1. Battery Care

• Charge the device fully before extended periods of non-use.
• Avoid completely draining the battery regularly to prolong its lifespan.
• The device supports recording while charging, which can be useful for very long sessions.
• In case of low battery during recording, the device will automatically save the current file before powering off to prevent data loss.

7.2. Storage Management

With 64GB of storage, the device can hold a significant amount of audio. Regularly transfer important files to your computer or cloud storage to prevent data loss and free up space for new recordings.

7.3. Cleaning

Wipe the device with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials that could damage the device.

8. Troubleshooting

• Device not turning on: Ensure the battery is charged. Connect to a power source and try again.
• Poor recording quality: Check the Gain and Bit settings in RECSET.txt. Increase Gain for quieter environments or decrease for noisy ones. Increase Bit for higher quality. Ensure the microphone is not obstructed.
• Voice Activated Recording not working as expected: Verify the Vor setting in RECSET.txt. Adjust the sensitivity (1-10) to suit your environment.
• Cannot find files on computer/phone: Ensure the recorder is switched to OFF before connecting. For Windows, ensure your default media player supports WAV files (Windows Media Player is recommended over Groove Music). For Android, ensure OTG is enabled in your phone's settings.
• Time is incorrect on recordings: Follow the time synchronization steps in the Setup section.
