The Sangean PR-D17 AM/FM Portable Radio was designed with special consideration for those with visual impairment. Practical voice prompts, large yellow high-contrast rotary control knobs, and preset buttons with raised symbols have been thoughtfully implemented, keeping the operation on PR-D17 simple and intuitive. Each button pressed is followed by a voice prompt to guide the user through each step of the way such as station browsing, alarm clock setting, radio station information, time, and other settings.
