The radio and its controls are housed in one cup, and you"ll be able to quickly tune to your desired AM or FM radio stations with the easily accessible seek/scan tuning buttons. Reception strength may vary depending upon location. You can also save up to 10-preset stations with a dedicated key that sits below the LCD screen, which offers a large-sized display of the radio frequency. Other controls include a combined on/off/volume control and a toggle button that switches between AM and FM radio. The LCD screen also offers a low battery indicator of all controls. You can also connect an optional MP3 player (such as an Apple iPod), CD player or other portable devices via the stereo input jack. Additionally, the WorkTunes headset protects your hearing from both the external environment and the music you"re listening to thanks to a volume control limiter that tops out at 85 dB. The radio and digital input are powered by 2 AA batteries (not included), which provide approximately 140 hours of operating time.
