DVS 150 Operation3-4
Freeze mode
Freeze mode locks the output display to the current image. Freeze mode can be
activated only by issuing an RS-232 command (see chapter 4 for
more information). If freeze mode is activated, the LCD screen
displays the message displayed at the left.
If input 4 (RGB pass-through) is selected, you cannot activate freeze mode.
You can deactivate freeze mode in the following ways:
• By issuing another RS-232 command
• By pressing the input button
• Automatically, if the scaler is in autoswitch mode and the input source changes.
Executive mode
Executive mode limits the number of operations available from the front panel.
This is useful for situations in which many end users operate the scaler, and you
want to prevent them from changing the adjustments you have made.
To enable executive mode, press the horizontal shift and vertical shift control
buttons simultaneously for two seconds. The LCD displays the
message at the left for eight seconds, and then changes back to
the default screens.
When executive mode is enabled, the only front panel button that can be used is the
input selection button. If any other button is pressed, the LCD displays the same
message for eight seconds, then changes back to the default screens.
To disable executive mode, press the horizontal shift and vertical shift control
buttons simultaneously for two seconds. The LCD displays the
message at the left for eight seconds, then changes back to the
default screens.
Resetting the scaler
You can perform two types of reset:
• Channel reset restores the factory default picture control settings (color, tint,
brightness, contrast, horizontal shift, and vertical shift) for only the currently
selected input.
If input 4 (RGB pass-through) is selected, you cannot perform a channel reset.
• System reset restores all factory default settings, including all picture controls for
all inputs, the output rate, and all configuration options available from the
LCD menu.
Channel reset
To perform a channel reset, press and hold the input button for two seconds. The
picture control settings for the active input are reset to their
factory default settings. The LCD displays a message similar to
the one at the left for four seconds, and then changes back to the
default screens.
System reset
To perform a system reset, press and hold the input button while attaching the AC
power cord. The picture control settings for all input sources,
the output rates, and the configuration options are reset to their
factory default settings. The LCD displays the message at the
left for four seconds, and then changes back to the default
screens.
