The incredible feature (we should say features…) of the RCA RP312A is the intended usage of this radio. The RCA RP312 is small enough to easily fit in the palm of your hand, and was manufactured with small slots underneath allowing this to be used with the included armband strap. This universal armband is designed to fit all size arms comfortably, allowing users to securely restrain the radio from bouncing all over the place while jogging.

So there is no excuse not to get out there, get the blood flowing, maybe even break a sweat. There is also no reason you have to miss the big game, or weather updates while your doing. Precise digital tuning ensures you will get the exact station you want, when you want it. Using the supplied earbuds in your hands, you can start enjoying these new benefits immediately.
