When “SETUP – DLT SAVING” is displayed, pressing the Mode button brings up the following menu:
SETUP DST Y
MAR 2 NOV 1
This submenu shows you a summary of all the daylight savings time parameters. The “Y” next to the “DST” indicates yes, daylight savings time is observed in your region. On the second line, there are 4 items, the spring forward month (March in this example), the spring forward Sunday (note that the 2 in this example means the second Sunday of March, NOT March 2nd), the fall back month, and the fall back Sunday.
This menu does not allow edits. It allows you to quickly see all the daylight savings time parameters. If you do not wish to change any of them, press the Up key to return to the previous menu. If you need to change any parameter, press the Mode key and cycle through the next 5 submenus. Changes made in each submenu are saved when you press the Mode key. If you press the Power button, you will exit Setup Mode and not save the change made in the current submenu. The default parameters shown below reflect the Energy Policy Act of 2005, which took effect in 2007.
