EDITING SOUND FIELD PARAMETERS

Repeat steps 2 through 4 as necessary to 
change other program parameters.
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 59).
Resetting parameters to the factory 
presets
Note
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.
