To power this Scope Clock box, use a wall wart (9V preferred) with a 5.5mm DC connector, center positive; this is the most widely used connector size.


This clock has an on-screen menu operated by the red push button located on the front. This button is also used to change the time and date. Of course, if you use the built-in GPS device, you'll never have to do this.


Also supported is automatic Daylight Saving Time for the US and EU zones (2008-2014). Configure your clock once and you'll always have accurate time!


Use the built-in Demo Mode to show off your gadget to friends and family. Select the Binary Clock mode to impress your friends and family!


Also included is a CD with several utilities to control the GPS device (Trimble Ace III) and a technical manual in pdf format. Changing the GPS device configuration requires some electronics expertise since you will have to provide your own RS-232 level converter for the control serial port. As shipped, the GPS device comes completely configured for use with the Scope Clock.
