The Zeitgeist Talking Time Machine is a voice output unit with clock, calendar, timer, and stopwatch functions, designed for use by individuals who are blind or have low vision. This portable electronic device combines a number of time-related functions and speaks through either its integrated speaker or headphones (not included). The unit tells time (including dual time zone) in hours, minutes, and seconds, and automatically adjusts to Daylight Savings Time and leap years. Its talking calendar tells the current day of the week, date, calendar week, number of days passed and remaining in the year, and the current zodiac sign. The user can set up to 10 different alarms, each with a separate signal, along with a stopwatch and two countdown timers (seven day and one hour). The unit manages up to 10 non-recurring or recurring appointments, and calculates age in years, months, days, minutes, and seconds or the day of the week for any date. The unit fits in a pocket or can be carried around the neck on the attached lanyard. It comes with instructions on audiocassette as well as a braille and large print quick-start sheet. OPTIONS: Spanish language version. POWER: Uses 2 triple-A batteries (included). DIMENSIONS (HxLxW): 1 x 4.5 x 1.25 inches.
