7. Technical Specifications

7.1. Memory Footprint (Approximate Recording Time)

The following table shows the approximate maximum recording time based on storage capacity and bit rate. Note that these are maximums for the device's storage capacity, not continuous battery recording time.

8. User Tips

• Adjusting Recording Volume (GAIN): If your recordings are too low, increase the GAIN setting in the RECSET.txt file. A higher number (up to 7) will make the boot recording louder.
• Voice Activated Recording (VOR): To enable recording only when sound is detected, set the VOR parameter in RECSET.txt to a value between 1 and 10. A smaller number makes the device more sensitive to quieter sounds.
• Compatibility: The V15 is compatible with Windows 2000 and above, Android, and Mac systems for file transfer and management.
• USB Interface: The device uses a Type-C USB interface for charging, data transfer, and connecting the wired remote control/headphones.
