How do I arm the system in AWAY mode?

Enter your security code followed by the [2] AWAY key. The touchpad will beep for the duration of the exit delay, display an armed AWAY message, and the red ARMED indicator will light. Leave the premises through an entry/exit door during the exit delay period to avoid causing an alarm. The touchpad beeps rapidly during the last 5 seconds of the exit delay to warn you that it is ending. (Page 15)
