With the DPR-640, you can enjoy music exactly how you want it. This handheld device receives DAB+ and FM signals. The easily readable display also shows the signal strength indicator. Additionally, a key lock prevents accidental operation. You can power the radio and charge the batteries with a standard USB adapter or use 2 AA batteries (not included), allowing you to use your radio during all outdoor activities. A handy battery status indicator lets you know how much power is left in your batteries, so you'll never be caught with dead batteries. This pocket radio can wake you up anywhere with one of its two alarms, either by radio or buzzer.
