D.MODE switch
When turned on, any USB port will not charge the BTR17 when connecting to external power supply, and will not use battery.
Desktop Mode
When turned on, BTR17 has more output power and voltage swing.
How to turn on desktop mode?
1. Turn on the D.MODE switch
2. Connect the external power supply to the POWER IN port to power the BTR17.
(5V2A adapter power supply is recommended: power supply voltage range 5 ± 0.3V, otherwise it may not be able to enable the desktop mode due to insufficient power supply.)
After the two steps above are completed, BTR17 can automatically enter desktop mode.
