How do I set a timer to automatically turn the unit off at a specific time?

Press the TOFF button and 'OFF' will begin blinking while the display shows the last set timer time. Press the up or down button to adjust the desired timer time, then press TOFF again to confirm; the display will return to showing the current time with 'OFF' shown. To cancel the timer off, press the TOFF button one more time until 'OFF' is no longer displayed. (Page 6)
