You've just opened the box, connected the battery and antenna.

Now what?

First, I recommend enabling the internal GPS. Steps to enable

If you are in a location where you think that the radio should be able to acquire a GPS signal, then wait for the GPS icon to stop blinking.

Once you have GPS signal put the radio in DR mode and select your closest repeater in the FROM field

Select Your Call Sign then Use Refelector for the TO field.

Listen, then talk!
