The Storage column contains one of the following values indicating when and where the parameter is stored.

"Global"

"Preset"

"-" = not stored or not applicable

Globally stored parameters are not changed when a preset is executed. Only one copy of a global parameter is stored. Global parameters are written to non-volatile memory each time they are changed. Globally stored parameters retain their values when the power is cycled.

Parameters stored in presets are changed each time a new preset is restored/executed. Preset parameters are not saved in non-volatile memory until a PRESETW command is executed. Parameters

stored in the power-on preset (see PRESETP) are restored when the power is cycled.
