Changing the Time and Date Default Settings You can change the time default setting from 12 hours to 24 hours or change the date default setting from month/day/year to day/month/year. To change the time or date default settings, follow the instructions below: 1. Press the clock button and then the pushbutton located under the forward arrow label until the time 12H and 24H, and the date MM/DD/YYYY (month, day, and year) and DD/MM/YYYY (day, month, and year) are displayed. 2. Press the pushbutton located under the desired option. 3. Press the clock button again to apply the selected default, or let the screen time out. Setting the Time (Radio with a Six-Disc CD Player) If your vehicle has a radio with a six-disc CD player, the radio will have a MENU button instead of the clock button to set the time and date. To set the time and date, follow the instructions below: 1. Press the MENU button. Once the clock option is displayed, press the pushbutton located under that label. The HR, MIN, MM, DD, YYYY (hour, minute, month, day, and year) will appear on the display. 2. Press the pushbutton located under any one of the time or date setting labels that you want to change. Every time the pushbutton is pressed again, the time or the date if selected, will increase by one. • Another way to increase the time or date, is to press the right SEEK arrow or the FWD button. 3. To decrease, press the left SEEK arrow or the REV button. You can also rotate the tune knob to adjust the selected setting. 277
