Yamaha RX-V557 owner manual Memory back-up, Resetting parameters to the factory presets

EDITING SOUND FIELD PARAMETERS

5Repeat 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 53).

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.
