To change the time default setting from 12 hour to 24 hour, press the clock button and then the pushbutton located under the forward arrow label. Once the time 12H and 24H are displayed, press the pushbutton located under the desired option to select the default. Press the clock button again to apply the selected default, or let the screen time out. Setting the Time (With Date Display) If your vehicle has a radio with a single CD player, the radio has a clock button for setting the time and date. To set the time and date, follow these instructions: 1. Turn the radio on. 2. Press the clock button and the HR, MIN, MM, DD, YYYY (hour, minute, month, day, and year) displays. 3. Press the pushbutton located under any one of the labels that you want to change. Every time the pushbutton is pressed again, the time or the date if selected, increases by one. • Another way to increase the time or date, is to press the right SEEK arrow or FWD (forward) button. • To decrease, press the left SEEK arrow or REV (reverse) button. You can also turn the tune knob, located on the upper right side of the radio, to adjust the selected setting. The date does not automatically display. The only way to see the date is by pressing the clock button when the radio is on. The date with display times out after a few seconds and goes back to the normal radio and time display. If your vehicle has a radio with a six-disc CD player, the radio has a MENU button instead of the clock button to set the time and date. 190
