With the med center system, taking your medications on schedule, every day becomes a party of your daily routine. How does it work? Set up to 4 daily alarms to alert you when your medication is due. A repeating friendly reminder notifies you of the time, the date and which daily dose to take. ("Good morning! Please take your morning pills for the 20th.") Press the "alarm acknowledged button" to confirm compliance and the med center talking alarm clock tells you when the next daily dose is due. Tri-date verification: matching the visual dates on pill boxes and clock with audible alerts assures accuracy. Talking alarm alerts users when it's time to take medication. Set up to 4 alarms daily to alert you when your medication is due. Loud & extra loud sound settings ensure the alarm is heard. Red & green color coding shows when daily dose is complete. The standard pill box (included in the med center system and all other standard med center organizers) has an individual dose compartment which measures roughly 15/16" wide x 1" long x 3/4" deep on the inside. Each pill box contains four of these dose compartments.
