Operating Modes
470A series time zone displays are user programmable to provide a wide range of operating features.
• 470A series time zone displays can be used as stand-alone units, deriving their timekeeping from a
highly accurate internal quartz crystal oscillator, or to operate as slave displays controlled by time
signals from many different sources.
• Each time zone can be programmed to automatically adjust for individual seasonal time changes
according to British, European or North American conventions.
• In small systems one 470A series display may be used to control up to ten similar units using a simple
single cable pair interconnection - please refer to page 3 for further information. In large systems a
482D, 4800 or 4850 series master clock should be used for centralised control.
