Troubleshooting

Before contacting your retailer or a Sony Support
Center, please check the following items. If the problem
persists, contact them.
The NSR does not work.
• Verify that the power switch is turned on.
• Verify that the power cable is connected correctly.
• Make sure the wall outlet has power. Test it by
plugging another device.
• Verify that the hard disk drives are not being accessed
(the HDD LEDs on the front of the recorder do not
blink), and then turn it off forcibly by pressing and
holding the power switch at the rear of the unit for
approximately 10 seconds. Restart the NSR.
• During the startup procedure, the NSR checks the file
system. The length of this check varies depending on
the amount of data on the NSR (in some extreme case,
it can take as long as two hours). During the file
system check, the HDD LEDs on the front of the
recorder blink.
• If the NSR does not start correctly, the following
screen may appear.
When it does, proceed as follows.
1. Select "7. Shutdown the system," and press the
Enter key.
2. Referring to "Cannot access the hard drive.",
verify whether the NSR hard disks are
correctly connected.
3. Restart the NSR and verify whether it starts.
