Trivia

• Although this model has a schedule, it is not equipped with an internal clock. It is up to the user to set the calendar to the current date, and it is not possible to set alarms.
• Inside the case of the Digital Diary there are pads for a serial connection. With the aid of these connectors (and a secret network menu), it is possible to copy the stored data to another SF-4000 or to a PC.
