5.5. Advanced Settings (via PC)

You can adjust various recording parameters by connecting the device to a PC and editing the `MRECSET.txt` file.

1. With the device off, connect it to your computer via the USB cable.
2. Open the "USB DISK" and locate the `MRECSET.txt` file.
3. Open `MRECSET.txt` with a text editor (e.g., Notepad). You will see parameters like TIME, GAIN, VOR, BIT, PART, and Noise reduction.

Parameter Explanations:

• TIME: Represents date and time settings (year, month, day, hour, minute, second). Must retain 14 digits.
• GAIN: Adjusts recording sensitivity (0-7). Higher numbers result in louder recording sound.
• VOR (Voice Activated Recording): Voice control settings (0-10). 0 is off. 1-10 enables voice activation; higher numbers require less sound to activate.
• BIT (Bit Rate Setting): Sets the recording bitrate.
  • 0: 32kbps
  • 1: 64kbps
  • 2: 128kbps
  • 3: 256kbps
  • 4: 384kbps
  • 5: 512kbps
  • 6: 768kbps
  • 7: 1024kbps
  • 8: 1536kbps
  • 9: 3072kbps
• PART: Recording segmentation (0-120 minutes). 0 means off (default 2 hours per file).
• Noise reduction: (0 is off, 1-7 is on). Smaller numbers indicate stronger noise reduction.

6. Maintenance

• Keep the device dry and away from extreme temperatures.
• Avoid dropping or subjecting the device to strong impacts.
• Clean the device with a soft, dry cloth. Do not use harsh chemicals or cleaning agents.
