Can you use this as an AM/FM radio outdoors where there are no plugins since it has a battery-operated feature?
This is advertised as a battery-back up product. I want to know if you can just run it off the batteries outside to listen to the radio when you don't need the alarm.
No you can not. It's just a battery backup if the power goes out. When the power comes on, the time and what not is still correct. Still need to plug in to AC outlet.
