Thanks, all! TrikeRadio and GrouserPad had the correct advice. I did a hard reset and coverted it to GMRS node.
1. Turn it off.
2. Press the * key and PTT at the same time, then turn it on.
3. A menu comes up offering: 1. Ham, 2. GMRS, 3. Normal.
4. Press 2 to get GRMS.
All set!
Many thanks for everyone's suggestions.
