  • This product is equipped with a lithium-ion battery.
    Even if you do not use this product for an extended period of time, you should charge it once every three months to prevent the internal lithium-ion battery from degrading.
    Ambient temperature range during charging
    5–35°C
    However, in order to take full advantage of the lithium-ion battery’s performance, we recommend that you charge it in a temperature range of 10–30°C.

  • Use cables with monaural mini phone type plugs to connect to/from the SYNC IN/OUT jacks. Do not use cables with stereo mini phone type plugs, as these cables do not work.
  • Do not connect an audio device to the SYNC OUT jack. Doing so may cause a malfunction.
  • If an external device is connected to the SYNC IN jack, the unit synchronizes with the clocks inputted to the SYNC IN jack, regardless of the MIDI Clock Sync setting.

  • Use cables with stereo mini phone type plugs to connect to/from the MIX IN/OUT jacks. Do not use cables with monaural mini phone type plugs, as these cables do not work.
