802 can operate either in "open" mode, which includes the ham frequencies; or it can operate only in the "marine" mode so it can transmit only on the FCC allocated marine frequencies.
If you don't have a ham license
, the safest thing to do is to place the radio
in the marine mode. This will protect you from accidently transmitting on the wrong frequency.
It's easy to do, and completely reversible if you later get your ham license
. See ICOM's instructions at: Icom America - Knowledge Base Article 57DG1541A3
In the marine mode, you should still be able to listen (but not transmit) on the ham bands.

P. S. I encourage you to get your ham license. It's fun !
