RESTORING FACTORY-DEFAULT SETTINGS

The procedure below outlines the process to restore factory-default settings. Before performing these steps, record custom settings on the installation worksheet (see page A-12). All parameters will be reset to their factory-default value. This procedure should be performed before setup begins.

To restore factory-default settings:

1.Record user-defined settings on the installation worksheet (see page A-12).

2.If the unit is on, place it into standby by pressing the

(standby) button on the remote control. If the unit is in standby, skip ahead to Step 3.

3.Power the unit on by pressing the@@@(standby) button on the remote control.

4.Quickly press and hold the MUTE button on the remote control until the following hidden menu appears:

FACTORY SETTINGS

EXIT

RESTORE DEFAULTS

The MUTE button must be pressed within 3s of powering the unit on. If the message “MUTE ON” appears in the top- left corner of the screen when the MUTE button is pressed, too much time has passed. Begin again with Step 2.

5.Use the up and down MENU arrows to highlight RESTORE DEFAULTS, then press the right MENU arrow to restore factory-default settings. (Selecting the EXIT option with the right MENU arrow will cancel the restoration of factory- default settings.)

6.The message “FACTORY SETTINGS HAVE BEEN RESTORED” will appear on the screen. Press any front panel or remote control button to restart the unit.

ROUTINE MAINTENANCE

The following routine maintenance should be performed on a periodic basis:

•Clean the exterior surfaces of the unit with a soft, lint-free cloth. Do not use alcohol, benzene, acetone-based cleaners, or strong commercial cleaners. Do not use a cloth made with steel wool or metal polish. If the unit is exposed to a dusty environment, a low-pressure blower may be used to remove dust from its exterior.

•Change the remote control batteries as needed. When the bat- teries are low on power, the remote control will enter a low- voltage condition that prevents it from operating the unit. Operation will be restored when new batteries are installed.
