When the STANDBY button is pressed, the display changes to read:
STANDBY MODE DISABLE
SIGNAL 0% Black
The word DISABLE indicates that Standby mode is disabled. Pressing the
front–panel ENABLE button toggles this choice between DISABLE and
ENABLE. The current signal selection is shown as Black 0% Setup, the factory
default. This selection is changed with the INCREMENT and DECREMENT
buttons, which scroll through the list of test signals available for use in Standby
mode:

When the desired signal is showing on the display, press the SAVE/RECALL
button to store the selection in the nonvolatile memory.
TEST SIGNAL Menu
The TEST SIGNAL menu selects the test signal for the rear-panel TEST
SIGNAL output. Making test signal selections does not affect any other aspect
of the VITS 200's operation.
All VITS selections, vertical characters, and any enabled standby text will be
applied to the selected test signal output while program video is present.
The behavior of this output when program video fails depends on how the VITS
200 is programmed to respond for Standby operation:
H If the VITS 200 Standby mode is disabled, the TEST SIGNAL output
will continue to provide the selected test signal, and the TEST SIGNAL
menu will continue to operate.
