Note:
- When RU7 is used as USB DAC for Windows-based systems, please install the custom-developed USB Audio device driver as provided on the Support page on the Cayin website
- RU7 does not have a Power on/off switch, please disconnect the Dongle DAC from the audio source when have completed your listening session. Otherwise, the RU7 will consume the battery of the audio source continuously.
