How do I mute the refrigerator alarms?

Alarms can be muted (except the 'power fail' alarm) by pressing and holding the 'freezer temperature up' key while simultaneously pressing the 'fresh food temperature down' key three times. This sequence must be completed within 5 seconds, and once muted, alarms will stay muted even if the refrigerator is powered down. To turn alarms back on, use the same key combination. (Page 13)
