Locking the Front Panel (Executive Mode)
To prevent access by unauthorized users or accidental changes to the DSC settings, you
can lock the front panel controls by placing the DSC in executive mode. In this mode, all
front panel buttons are disabled and control is available only by SIS commands.
To lock the front panel, do either of the following:
• Press and hold the front panel Menu and buttons until the OSD displays the
message Executive Mode Enabled (approximately 5 seconds). The message remains
on the OSD approximately 2 seconds.
• Enter the Enable SIS command (see the Front Panel Lock (Executive Mode)
commands on page 59).
To unlock the front panel, do either of the following:
• Press and hold the front panel Menu and buttons again until the OSD displays
the message Executive Mode Disabled (approximately 5 seconds). The message
remains on the OSD approximately 2 seconds.
• Enter the Disable SIS command (see the Front Panel Lock (Executive Mode)
commands).
Resetting
Resetting the unit causes various settings to revert to the defaults that were set at
the factory. Resets can be performed from the front panel buttons, the OSD, or SIS
commands. The following resets are available:
• Factory defaults: This reset clears all user-specified settings but retains the latest
firmware version. You can perform this reset by:
• Selecting Factory Reset from the Advanced submenu of the OSD (see the
Factory Reset option of the Advanced submenu on page 33)
• Entering the Reset all device settings to factory default SIS command
(see the Reset command on page 60)
When the reset is complete, the message Factory Reset is displayed on the OSD.
• Factory Firmware: This reset returns the unit to its factory default settings, including
the original firmware with which it was shipped. All user settings are cleared.
To perform this reset, press and hold the Enter button for 20 seconds while applying
power to the unit. When the reset is completed, the message Firmware Reset
appears on the OSD.
NOTE: The Firmware Reset and Factory Reset messages are displayed for 1 minute
after the reset to allow time for the display device to sync with the DSC output.
