DB-30: Disabling Auto Power Off
The DB-30 contains a feature called "Auto Power Off" that shuts off the power automatically when no operation or adjustment has been made within 60 minutes. This can help prolong the life of the battery. Use the following procedure to disable the Auto Power Off function:
1. Power on while holding the TAP/MUTE button. When "OF" shows in the display, the function will be disabled, and you can release TAP/MUTE.
Note: The function will be enabled again the next time the power is turned on.
