7. How to Use the Desktop Mode on the DM15 R2R?

Desktop Mode ((FiiO Patent)) Power Supply Method

When D.MODE is enabled, the device operates using an external power supply. In this state, the battery is not charged, and performance is enhanced.

When D.MODE is disabled, the device operates using battery power.

Note: When the battery level is at 0%, the battery will be charged regardless of whether D.MODE is enabled or disabled.

Usage Scenarios

Portable Scenario: Set the D.MODE switch to OFF. If the power adapter is not connected and D.MODE is switched ON, the DM15 will shut down.

Desktop Scenario: Set the D.MODE switch to ON. This helps extend battery lifespan and increases power output.
