Several useful functions are in the Advanced Settings Menu. To get to the Advanced Settings
Menu, Press .or ,until YES is displayed for the first screen of the configuration menu
that looks like this:
The configuration of the SCU-2200 can be saved into the SCU-PDM2. The SCU-PDM2 can
then be moved to another unit (must be the same part number) and the configuration loaded into
the new unit.
• Enter Advanced Settings menu and then press .or ,until MEM is displayed for SETUP.
Press ;.
• To save the configuration into the SCU-PDM2. Press .or ,until SAVE is displayed for
MEMORY. Press ;.
• To load the configuration from the SCU-PDM2 into the SCU-2200. Press .or ,until LOAD
is displayed for MEMORY. Press ;.
Password Protection allows the user to create a 4-digit password
(0000-9999) to prevent tampering with configuration settings if the SCU-PDM2 is left mounted
to the front of the signal conditioner.
