Slide the battery onto the back of the radio until you hear a distinct click. The manual emphasizes ensuring the contacts are clean. Never force the battery.
FM Reception: The telescopic antenna is optimized for FM reception. Fully extend the antenna and swivel it for the best signal. For weak FM signals, an external 75-ohm antenna can be connected (sold separately).
AM Reception: The DX-AR-8108 utilizes a built-in ferrite bar antenna for AM. Rotate the radio body for the best signal nulling (to reduce interference).
