Verify communication
Check that a radio (or another keyloader) answers before you rely on the cable, the adapter and the connection.
Verify communication sends the radio the standard's opening handshake and waits for its answer. Nothing in the radio changes. Use it after connecting a new cable or adapter, or before a large load.
Run the check
Connect the radio over three-wire or USB, and turn it on.
On the main menu, tap Verify communication. The check starts at once:
