1. Check to see that PRESET is OFF.
2. Use the CP 3810 to select the destination(s).
The “page” of eight destinations can be scrolled with the arrow buttons to display up to 80 possible destinations. The
selected output button(s) will glow “high” green to show it will be affected by the switch.
3. Use the Main panel to select the source. This completes the switch.
When one of the source buttons is pressed, a Take command is issued to all levels of the switcher matrix. (Press the TAKE
key is not necessary.) A status signal is then returned to the control panel; this confirms the action by lighting the input
button that was pressed and displaying the name of the input in the “Current” window of the Main panel and the appropri-
ate windows on the CP 3810.
This action does not affect the output being controlled by the Main panel.
If the CP 3810 has been configured for “sticky output” operation (CP 3810S), selected outputs will remain selected until
the Take/Select button(s) are toggled off.
If entry of a password is requested on the Main panel (“PASS =00”), the output about to be affected has a password level
higher than that of the panel. For more information about passwords, refer to the operation instructions for the Main
panel.
