The LR-300 Digital Receiver is a low-cost digital receiver. It has the same exceptional audio quality as Listen's full-featured receivers and the same convenient recharging options, but it doesn't have the LCD display. It has 17 wide band channels to select from and channel SEEK capabilities, located behind a lockable door. It takes AA batteries (alkaline or NiMH rechargeable). SmartChargeTM capabilities prevent overcharging. An LED indicates power to the unit.
