Using the DeWalt DCR028B is easy. First, you can choose to power it with the detachable AC power cord or insert a DEWALT® 12V MAX*, 20V MAX*, or FLEXVOLT® battery (which you'll need to buy separately). To start streaming music, pair your device with the radio via Bluetooth within 100 feet. You can also connect an external device through the 3.5 mm auxiliary port. For AM/FM radio, use the six presets to save your favorite stations. There's a USB port on the radio, so you can charge your mobile device while listening to music. When it comes to maintenance, keep the radio clean by using a dry cloth. Avoid exposing it to extreme temperatures and moisture. Also, when you're not using the radio, store the antenna in the handle for protection. Remember, the radio comes with a 3 - year limited warranty, so if you have any problems, contact the manufacturer.
