Setting The Time, The First Time IMPORTANT: The first time you connect your new SmartSet clock radio to the AC outlet the internal computer will automatically set the time correctly for the Eastern Time Zone, which is the initial default setting. The display will scan for a few seconds and then show the correct Day and Time in the Eastern zone. If you live in the Eastern Time zone, there's nothing else to do. Your clock is set correctly and running. If you do not live in the Eastern Time zone you must change the default zone display to your own zone. You only do this one time and the SmartSet will remember the new default zone setting and will always return to that setting after a power interruption. There are 7 time zones programmed into your SmartSet clock radio as follows: ZONE 1 - Atlantic Time ZONE 2 - Eastern Time (Default Setting) ZONE 3 - Central Time ZONE 4 - Mountain Time ZONE 5 - Pacific Time ZONE 6 - Yukon Time ZONE 7 To c h a n g e t h e d e f a u l t t i m e z o n e d i s p l a y, depress the TIME ZONE button.
