Setting the Time (Without Date Display) If your vehicle has a base AM/FM radio with a single CD player and preset buttons numbered one through six, the radio will have a clock button for setting the time. You can set the time by following these steps: 1. Press the clock button until the hour numbers begin flashing on the display. Press the clock button a second time and the minute numbers will begin flashing on the display. 2. While either the hour or the minute numbers are flashing, rotate the tune knob clockwise to increase or counterclockwise to decrease the time. Instead of using the tune knob, you can also press the SEEK, FWD, or REV buttons to adjust the time. 3. Press the clock button again until, the clock display stops flashing to set the currently displayed time; otherwise, the flashing will stop after five seconds and the current time displayed will be automatically set. Setting the Time (With Date Display) If your vehicle has a radio with a single CD player, the radio will have a clock button for setting the time and date. Press the clock button and the HR, MIN, MM, DD, YYYY will appear on the display. 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, will increase by one. Another way to increase the time or date, is to press the right SEEK arrow or FWD button. To decrease, press the left SEEK arrow or REV button. You can also rotate the tune knob to adjust the selected setting. 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. Press the MENU button. Once the clock option is displayed, press the pushbutton located under that label. The HR, MIN, MM, DD, YYYY will appear on the display. To change the time or date, follow the instructions given earlier in this section. To change the time default setting from 12 hour to 24 hour or to change the date default setting from month/day/year to day/month/year, press the clock button and then the pushbutton located under the forward arrow label. Once the time 12H and 24H, and the date MM/DD/YYYY and DD/MM/YYYY are displayed, press the pushbutton located under the desired option. Press the clock or MENU button again to apply the selected default, or let the screen time out. 3-60
