12.6. Protect Settings
Operation misses can be avoided by protecting front panel-mounted key operations.
Tips
• To make subsequent protections valid when the power is ON after the initial Protect function settings, save
the configuration (p. 60). (However, if the Protection function is enabled in the way described below, the
configuration save needs not be performed because the latest configuration including the Protection function
settings are automatically saved at the moment of the key operation.) Settings are saved as system data,
and setting status is maintained even if the preset memory is recalled.
• Control operations can be performed either by way of the RS-232C port or the remote control module even
when in protection mode.
• Configuration can also be saved by pressing the Setting knob at this screen.
