Ailunce HD1 is a DMR amateur walkie-talkie that can be written with computer software. But before installing and using the programming software, we need to install the HD1 dedicated driver software correctly.

Each file contains the .exe file, then we need to install the appropriate driver according to our needs. if your computer system is XP, then choose to install the driver in the "98ME_2k_XP" folder; if your computer is Windows 7/8/10, then choose the driver in the "win7" folder.

Or directly double-click "Vista3200_win7" and follow the prompts to complete the installation.
