Moreover, the problem might be caused by something other than this unit. Please also check the operation of the connected units. If this product still does not operate correctly, contact the retailer where you purchased it. General The unit does not turn on. e Insert the power plug into an outlet. e Check the connection of the power cord to this unit. The unit automatically turns off. e This is because the automatic power saving function turned the unit off. Press the POWER button on the main unit to turn it on. Change the automatic power saving setting if necessary (page14). The unit does not respond when buttons are pressed. e Multiple button presses without pause can cause the unit to stop responding. After pressing a button, wait momentarily for the unit to respond. There is noise. e Place the unit as far away as possible from TVs and other devices that have strong magnetism. No sound is output from the speakers. The sound is distorted. e Check the connections with the amp and the speakers. e Adjust the volume of the amplifier and other devices. e No sound is output when playback is paused. Use the app to resume ordinary playback. Clock sync The CLOCK indicator does not stop blinking. e Set clock mode to OFF when not using it. e A clock signal to which the unit cannot synchronize might be being input. Confirm that the clock output frequency of the clock generator is 10MHz. In addition, check the connection of the 10MHz IN CLOCK connector and the settings of the con- nected devices. A cyclical noise is being output. e If a cyclical noise is being output when the unit is in clock mode, the connected device might not also be in clock mode. Check the connection of the 10MHz IN CLOCK connector and the clock mode setting of the connected device. An audio file cannot be played back (correctly). e Different media servers (NAS) support different types of files. Check the specifications of the media server (NAS), too. The sound breaks up during playback. e If files that use lossy compression, including MP3s, and files at 44.1kHz and other low bit rates play back normally, but the sounds of files at 384kHz and other high bit rates as well as FLAC and other files that use lossless compression break up, the ETHERNET speed might be too slow. The audio data is transmitted from the NAS through the router. For this reason, using LAN cables to connect the NAS to the router and the router to this unit is preferable. The sampling frequency (DSD 22M) is not shown. e Update the firmware to version 1.03 or newer. Troubleshooting Restoring factory settings Settings are retained even if the power plug is disconnected. Follow these procedures to restore all settings to their factory defaults and clear the unit’s memory. Press the POWER button while holding down the MENU button on the main unit.
