8. How to switch the six working modes?

The M27 supports six working modes in total, including Android mode, Pure Music mode, Bluetooth Receiving mode, USB DAC mode, Coaxial Decoding mode, and AirPlay Receiving mode.

The Android mode is as default for the first use, which can be switched on the drop-down menu or Settings->Working mode menu.

In Pure Music Mode, only the FiiO Music app is running, eliminating interference from other applications for a purer music experience.

In non-Android mode, you can tap the working mode icon in the upper left corner of the display to switch to other modes, or tap Settings to return to the Android mode.
