Detect |
While the Icon lights 1 second,
when there is no ANALOG INPUT OVER detection, the Icon stops lighting and returns to normal display. |
To detect the over-input of the
analog audio to
the A/D converter. When the Icon lights frequently, output level of the source equipment is high and a sound is distorted. Turn on the Analog Att switch. |

UPDATE PANEL Mode (Version update)
Preparations
UPDATE PANEL Mode (Version update)
1. Copy the UPDATE FILE to the root directory of the USB Memory.
Note: NEVER copy several UPDATE FILES to the root directory of the USB Memory.
Copy only the corresponding UPDATE FILE.
Enter the UPDATE PANEL mode.
Check a current version.
2. Turn off the power to this unit by setting Multi-Zone to "OFF".
3. Connect the USB Memory to the USB terminal (A type) of the front panel.

Procedure
1. While
holding down "TUNE↑" key on the front panel, press "STANDBY
ON/OFF" key and moves to the UPDATE PANEL mode.
2. The updating process is as follows.
2. The updating process is as follows.
Front Panel Key
[DOWN] : TUNE key
[UP] : TUNE key
[LEFT] : PRESET key
[RIGHT] : PRESET key
[DOWN] : TUNE key

If no key is
pressed within 10 seconds while booting UPDATE PANEL, the UPDATE PANEL is
finished and returns to the normal display. But the process does not become
timeout and continues while "FILE searching" or "Updating
