Roland HP507 用户手册

You can change the language that is displayed in the screen.

With the factory settings, the unit’s power will automatically be switched off 30 minutes after you stop playing or operating the unit.
If you don’t want the power to turn off automatically, change the “Auto Off” setting to “Off” as follows.

This setting is automatically saved in the HP507.

The HP507’s settings will return to their default settings when you turn off the power, but you can store these settings so that they will retain the 

changes you made even after the power is turned off, then on again.

When you execute the “Factory Reset” function, the settings you’ve edited in Function mode will be restored to their factory-set state.

Save your settings as described in “Memory 

Backup” (p. 44).
