Operation, cont’d
DVS 100 and DVS 150 Operation 3-4
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) of the DVS 150 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 selection 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) of the DVS 150 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 selection 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.
