Firmware upgrade
- What is firmware:
- That is, the software control system of the turntable itself needs to upgrade the firmware when new functions are released or some original problems are corrected.
-
- Upgrade method:
- Download the released firmware package update_hm1.bin file to an SD card(It doesn’t matter if there are other files in the card)
- And copy this file to the root directory of the SD card, press and hold any button on the panel without releasing it, turn it off and then turn it on again, the interface will be upgraded automatically, and you can release the button.
-
- What should I do if the power is interrupted during the upgrade process?
- The turntable itself has a protection function, and the system will not be damaged if the power is interrupted at any time during the upgrade process.
