How to change video parameter (example):
Step 1: For example, you start with this status menu:
Step 2: Press the MENU button
Observe that the setting cursor appears. The arrows indicate that you
now can change the value at the cursor position with the arrow buttons.
Press MENU repeatedly to change the position of the cursor. If you don’t
wish to change anything, just press RETN to return to the status menu.
Step 3: Press one of the ARROW buttons. It doesn’t matter which one.
Observe that the current parameter at the cursor position is displayed.
Video standard and video format are shown. Everything else is blanked out.

Step 4: Press the DOWN ARROW button (two times in this example)
The video standard changes from SMPTE 274M-9 to SMPTE 274M-11,
and video changes from 1080p25 to 1080p23.98.
You can press up/down arrow buttons repeatedly to scroll though the list of formats.
Step 5: When you are satisfied with your choice, press the RETN button
The unit will return to the status menu and show you an overview of your settings.
Remember that pressing RETN will always bring you back to the status menu.
No need to worry about saving. The unit automatically saves your setting when you
change anything.

SOURCE:
INTERNAL: The unit runs on the internal oven crystal clock oscillator.
44.1 kHz to 10 MHz (see list below) : Enabling external synchronization at the selected frequency.
CLOCK OUT:
44.1 kHz to 6.144 MHz (see list below): It shows the selected word clock output frequency. It also shows the sampling
frequency for AES and SPDIF outputs. However, the sampling frequency for AES and SPDIF is limited to a maximum of
192 kHz. (see details in the list below.
VIDEO OUTPUT:
SD and HD Video formats (see list below): It shows the selected video format.
STATUS:
Shows the status of the unit: When the unit runs on INTERNAL, the status is shown as LOCK. When a change of video
format or clock frequency is made, the unit will briefly display WAIT until all phase locked loops have settled. Typically this
will last for less than 1 second.
When any external sync is selected (44.1 etc.) and no input sync is present at the BNC connector at the back, the unit will
display - - - - to indicate that no external sync is present. When the incoming sync is at a valid frequency, the unit will
perform a phase lock and display LOCK.
OBS: When the incoming sync is invalid, for example if it is at a different frequency than the SOURCE setting, the unit will
not lock, and the display will show ERROR.
There is a hidden setting in the STATUS position (the only one in the unit): Press the menu button until the arrows cursor
is at the STATUS position, and then press the up- or down arrow. You will then be presented with the choice TS OFF or
TS ON. This setting controls the Test Signal embedded in the video output: Color bar for PAL and NTSC formats, hatch
pattern (grid) for all other formats.
This feature is meant as a test tool for tracking down problems in installations. It is irrelevant for synchronization purposes.
