Ok, you are fine it is just operator error/misunderstanding

.
When you turn on the radio it goes to "16" which is the "Distress Safety Calling" channel. After it scrolls a few times it just goes to a tag line of "Distress". If you go to other channels, you will see other "tags" based on their specific use. It doesn't have anything to do with the DSC function. You are good to go.
Have fun in the San Juans!
