EDITING SOUND FIELD PARAMETERS
5
Repeat steps 2 through 4 as necessary to
change other program parameters.
Note
You cannot change parameter values when "MEMORY
GUARD" is set to ON. If you want to change the parameter
values, set "MEMORY GUARD" to OFF (see page 61).
Memory back-up
The memory back-up circuit prevents the stored data
from being lost even if this unit is set in the standby
mode, the power cord is disconnected from the AC
outlet, or the power supply is temporarily cut due to
power failure. However, if the power is cut for more
than one week, the parameter values will return to the
factory settings. If this happens, edit the parameter
value again.
■ Resetting parameters to the factory
presets
Use PARAM. INI (see pages 61).
