Cayin N3 Firmware Upgrade

· Each version of firmware might contain minor different, consumer please decide on your own accord whether you need to update the firmware of your N3 DAP.

· Under normal circumstances, firmware upgrade will not cause any damage to user information, but Cayin cannot exclude the possibility of upgrade failure due to mal-operation or any other reason. For these reasons, you might be required to format your N3 DAP and result in losing person data stored on the player. We strongly suggest you backup all your personal data stored on the player before you perform firmware upgrade.

· The N3 firmware cannot be used in other product, and the firmware from other product cannot be used in N3

   · While N3 has been turned on, select “System Setup” and scroll all the way to the bottom of the list, select “System Update”, the system will complete the upgrade process automatically, and reboot the player after update is completed.

   · While N3 has been turned off, hold the round physical “Enter” button, and then hold the “Power on/off” button, the system start the firmware upgrade process and will complete the process automatically.  It will reboot the player after update is completed.
