If you press [ENTER], the connection between the DR-880 and the computer will be forcibly terminated. In this case, it is possible that the recovery will be incomplete, causing the operation of the DR-880 to later become unstable.
FACTORY RESET INSTRUCTIONSYou can restore the DR-880 to the condition it was in when it left the factory. This operation is called “Factory Reset.”
When you execute Factory Reset, the user data will return to its factory-set condition. If the DR-880 contains important data you want to keep, use Bulk Dump (p. 131) to save the data on an external MIDI device, or use USB backup (p. 138) to save the data on the computer before you execute Factory Reset.
1. With playback stopped, press [EDIT].
The edit menu screen appears.
2. Move the cursor to the “FACTORY RESET” icon and press [ENTER].
The display will ask “Factory reset?”fig.11-010d
3. If you’re sure you want to execute Factory Reset, press [ENTER]. If you decide to cancel without executing, press [EXIT].

10-1. Check the [MASTER OUTPUT] waveform.fig.outputdacheck2.eps
VOLT/DIV:2V TIME/DIV:1mS
10-2. Slowly turn [MASTER VOLUME] toward the minimum position.Verify that the square wave shown in the illustration from “OUTPUT L/R” gradually decreases.
10-3. Slowly turn [MASTER VOLUME] toward the maximum position.Verify that the square wave shown in the illustration from “OUTPUT L/R” gradually increases.
* Note: The waveform must not abruptly increase or cut out.
* Note: Misshapen waveforms or waveforms below the nominal level are NG.
10-4. Disconnect the plug from [MASTER OUTPUT] R, and check the waveform.fig.outputdacheck3.eps
10-5. Insert the plug back into [MASTER OUTPUT] R, and check the waveform.fig.outputdacheck4.eps
10-6. Disconnect the plug from [MASTER OUTPUT] L (MONO), and check the waveform.fig.outputdacheck5.eps

11. AF Gain checkfig.afgaincheck1.eps
Input a square wave (200 Hz, 100 mVp-p) from the “GUITAR/BASS INPUT.”
Check the square wave that is output from “MASTER OUT L (MONO)/R.”
fig.afgaincheck2.eps
Amplitude: 1.3--1.5 [Vp-p]
Press [BANK] to proceed to the next test item.
12. IN-OUT check, Residual Noise checkfig.inputadcheck1.eps
12-1. Check the “MASTER OUT” L (MONO)/R waveform.Input a sine wave (200 Hz, -10 dBm) from the “GUITAR/BASS INPUT.”
On your oscilloscope, set VOLT/DIV to 5 [V].
Check the sine wave that is output from “MASTER OUT L (MONO)/R.”fig.inputadcheck2.eps
VOLT/DIV:5V TIME/DIV:1mS
Amplitude: 9.0--12 [Vp-p]
If distortion is visible in the waveform, the result is NG.

12-2. Check the residual noise of “MASTER OUT” L (MONO)/R.Listen to the noise, and verify the following.
1. Noise level: -73 dBu or less (both L and R)
2. No abnormal sound is present in the output.
3. No abnormal sound is produced when you apply physical shock to the unit.
12-3. Check the residual noise of “MASTER OUT” (PIN).Listen to the noise, and verify the following.
1. Noise level: -82 dBu or less (both L and R)
2. No abnormal sound is present in the output.
3. No abnormal sound is produced when you apply physical shock to the unit.
12-4. Check the residual noise of “INDIVIDUAL.”Listen to the noise, and verify the following.
1. Noise level: -77.5 dBu or less (both L and R)
2. No abnormal sound is present in the output.
3. No abnormal sound is produced when you apply physical shock to the unit.

ERROR MESSAGES
Buffer full!
Cause 1: Too many MIDI messages were received all at once, and the DR-880 was unable to process all of them.
Action 1:Reduce the volume of the MIDI messages being sent by the transmitting device.
Cause 2: You attempted to play back an excessive amount of data, and the DR-880 was unable to process all of it.
Action 2:Reduce the amount of data being played back, or slow down the playback tempo.
Checksum error !
Cause: MIDI Exclusive messages could not be received correctly during a Bulk Load operation.
Action: Try the operation again.
File error !
Cause: During an SMF Import, you attempted to use a file of a type other than those specified, or one that is invalid.
Action: Use the specified type of file.
Memory full !
Cause: Memory is full.
Action: Save the pattern/song you are creating, and then delete unneeded patterns or songs.
MIDI off line !
Cause: A MIDI Active Sensing error has occurred. An abnormality has been detected in the device or cable connected to MIDI IN.
Action: Check the device or cable connected to MIDI IN.
Not supported !
Cause: You attempted to import SMF data that the DR-880 does not support.
Action: Check that the SMF is in a format that can be imported by the DR-880. (p. 135)
Now working...
Cause: Data is being processed.
Action: Please wait until the message disappears.
Now writing...
Cause: Data is being saved to memory.
Action: Never turn off the power while this message is displayed.
* If you turn off the power while this message is displayed, it is possible that previously saved data (in addition to the data now being written) will also be lost.
Too busy !
Cause: The system attempted to concurrently process abnormally large amounts of data, but was unable to succeed.
Action: Make sure that the unit is not being forced to handle an overly large amount of data (in patterns, or received MIDI messages) all at once, and try to reduce the amount of data.
Use pattern mode.
Cause: You attempted to use EZ Compose or Groove Modify in Song mode.
Action: Switch to Pattern mode before using EZ Compose or Groove Modify.
User data is damaged. Factory Reset
Cause: The data in the DR-880’s internal memory is damaged. (This message will appear when you turn on the power.)
Action: Press [ENTER] to reset the DR-880 to the factory-set condition.
System error !
Cause: An unknown error has occurred in the system.
Action: Immediately stop using the unit, and consult your dealer or nearest Roland Service Center.
