Using the DeWalt DCR028B radio is easy. First, you can power it up. You can either use the detachable AC power cord or insert a DEWALT® 12V MAX*, 20V MAX*, or FLEXVOLT® battery (you need to buy the batteries separately). Once it's powered on, you can connect your device via Bluetooth. Just turn on the Bluetooth on your phone or other device and pair it with the radio. You can stream music from up to 100 feet away. If you don't want to use Bluetooth, you can connect an external device through the 3.5 mm auxiliary port. For the AM/FM radio, you can set your six favorite stations as presets for each band. There's also a USB port on the radio. You can plug your mobile device into it to charge. When it comes to the antenna, use the innovative handle to store and protect it when you're not using the radio. As for maintenance, keep the radio clean. Wipe it with a dry cloth regularly. Don't expose it to extreme temperatures or moisture. If you drop it, check for any visible damage. Remember, this radio comes with a 3 - year limited warranty, but following these steps will help it last even longer.
