Polycom Vortex EF2280 User Manual

● "-" = 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.
