As your Icom is 'brand new' as you described it, I would strongly recommend to contact Icom support
Technical Support Department
Dedicated number 800-253-1498
Monday - Friday 4AM to 5PM PST
They are there to help you.
Just in case you are wondering: I did not find a number for Icom support in Argentina (based on your call) nor did I find a satisfying answer from Icom UK website (based on the fact that your user profile lists UK as your location).
However you may just want to contact Icom UK, to see if they have a support department locally to you.
Failing all that, you can try to contact the Japanese headquarters support
