1. Press down repeatedly on the GROUP switch until the display reads TIME.
2. Release the switch. You are now in the Configuration Group.
Figure 4-1 shows the switch and indicator locations.
4.2.2 Display and Change Items in Basic Configuration Group
1. Press down repeatedly on the SET/NEXT switch until the display shows the menu you want to
