Section 8: Operating Instructions

sources on the Zones Keypad or via the IR Receiver.
POWERING THE ZONE ON AND OFF
The zone can be powered ON from the Keypad in two different ways:
1. Press the POWER Button on any keypad to turn the zone ON. If Power Management has been
enabled, and ALL zones were previously OFF, the source components will also power ON.
2. Pressing any SOURCE SELECTION button (located above and below the LCD display) when the
Zone is OFF will power the Zone ON and change to the selected source. If Power Management has
been enabled, and ALL zones were previously OFF, the source components will also power ON.
