Does anyone have instructions on the proper way to set the factory Peterbilt clock in the sleeper? 2005 Peterbilt 379, 63" flat top. I've finally got the time set, but I'm not sure how I did it. Now I need to know how to set and turn on and off the alarm.
If it's like my 387, is almost self explanatory. Mine had 4 buttons, time, alarm, hour, min. Push time and hold, then hot and minuet to count up. Do the same for alarm. To set the alarm, push both time and alarm to turn on and off. Hold hour and minuet to adjust brightness.
I have 2013 579 with small round sleeper clock. To set time hold button labeled snooze with clock hand symbol and push h or m buttons to change time. Then hold button label stop with speaker symbol and put h or m button to set alarm time.
Hit the mode button.The year will start flashing.Then hit the sel button until the hours start flashing on clock.Press up or down the press the sel.button and the mins.will flash.Press up or down.When u get it set,press mode.
