USB-C Cable：
Coaxial Cable：
Connect the coaxial cable to an external DAC, to allow
the DX240 to work as a digital transport.
Connect the USB-C cable to a computer for charging,
data transfer, and USB-DAC function.The USB-C cable
can also be used with a USB charger to charge the
battery.
Clear TPU protection case:
Use the TPU protection case to protect the DX240
chassis from scratches.
Screen Protector：
Use the screen protector to protect the DX240 screen
from scratches.
Warranty Card：
The warranty card will be requested at the time of
warranty repair. Please retain the warranty card.
Quick Start Guide:
This reviews the basic functions of the DX240.
Balanced Burn-in Cable：
Plug the burn-in cable into the output socket and keep
playing music to burn-in the DX240. The burn-in process
helps the DX240 sound reach its full potential by forming
the capacitors and stabilizing the electronic components
used.

4
Tips for burn-in
The use of the cable is very straightforward. The burn-in
cable is used to form the capacitors and to condition the rest
of the circuitry. The method for burn-in is to use normal
resolution music, as higher resolution causes more heat due
to the higher demand on the system. Also, use a normal
listening volume, as the higher volume will have a higher
power consumption therefore more heat will be generated.
While burning in the DX240, both the balanced and the single
ended components are being affected and burned in.
The burn-in time can be from 100 to 200 hours and the
burn-in doesn't have to be continual. You can power off the
player and continue the burn-in process after a few days. It
is also not mandatory to use the burn-in cable, we supply it
as a convenience for when you are not listening to the DX240
and you would like to get your dap conditioned as soon as
possible. You can also just listen to the player and enjoy the
music as your player goes through this process while playing
through IEMs or headphones.
