Warm Usage Tips
1. The original matching antennas are compact, which may lead to weaker induction sensitivity. To expand control range:
  • Purchase a separate 3.5mm large external antenna;
  • Attach a metal sheet or metal rod to the original antenna;
  • Place metal blocks on the antenna for stronger signal reception.
2. Turn on the device and let it warm up for 5 minutes, then the pitch sensing will become much more stable during playing.
