[IHD-410PT/IHD-410PR] Why did it fail when upgrading firmware?


  1. The IHD-410PT has a different firmware from the IHD-410PR, so please choose the correct firmware before upgrading the firmware.
  2. Do not interrupt the upgrading procedure.

User should upgrade the firmware for every unit. (For example, if there are 3 Rx’s, user should update for 3 times.)
