How do I set the Timer ON function to start the air conditioner automatically?

Press the TIMER ON button to display the last auto-on setting time and the signal 'H' on the LCD. Press the TIMER ON button again to set the desired time — each press increases the time by 30 minutes between 0 and 10 hours, and by 1 hour between 10 and 24 hours. After setting, wait approximately 3 seconds for the remote controller to transmit the signal and return the temperature display. (Page 6)
