The new firmware corrects a number of Issue and offers improvements to the radio

  1. Fixed an audio problem when switching the band while receiving in the FM mode.
  2. Fixed a DTCS and tone squelch decoding problem when receiving in the 9600bps mode.
  3. Fixed an improper S-meter indication problem when the mode is changed while receiving.

Additionally, a USB3 compatible driver and cloning software update CS-9100 Rev. 1.01 is downloadable from the Icom website.

its suggested you make sure you backup memories and settings for your radio, this upgrade suggests it wipes the radio memories (however my device retained all memories)
