System Reset; Front Panel Lockout (Executive Modes) - Extron electronics DVS 304 User Manual

System Reset

For a scaler reset, the DVS 304 can return to default values by holding down the Input 1
button while simultaneously plugging in the power cord. The System Reset message will
be displayed on the LCD screen.

Front Panel Lockout (Executive Modes)

To prevent accidental changes to settings, press the Menu and Next buttons
simultaneously for 2 seconds to enable the DVS 304's front panel lockout mode, also
known as executive mode 1.
Executive mode 1 locks all front panel functions except input switching and preset recall.
The menu system returns to the default menu within 10 seconds. The DVS 304's front
panel is affected by executive mode, but the IR 902 remote is not. See "IR 902 Infrared
Remote Control" later in this guide for information.
When executive mode 1 is active, all functions and adjustments can still be made through
RS-232 control. For details on RS-232 control, see "Communications and Control".
To disable executive mode 1, press the Menu and Next buttons simultaneously for
2 seconds. See the flowchart below.
Executive mode 2 locks all front panel functions completely. This mode can be enabled or
disabled by SIS commands only.
