There are two NSR-S20 version upgrade methods: upgrading from the Setup menu and upgrading using
recovery files.
For upgrading from the Setup menu, refer to “Firmware Update” in the User’s Guide.
This section describes upgrading using recovery files. Use this method if the NSR-S20 cannot be started
or you want to reset the password.
Equipment and Tools
.Recovery files

n
For how to obtain these recovery files, contact your local Sony Sales Office/Service Center.
.USB flash memory (with a device recognition LED)
n
Use the USB flash memory formatted by the FAT32.
Preparation
1. When the NSR-S20 can be started, store the configuration data in the USB flash memory.
n
For how to store the configuration data in the USB flash memory, refer to “Importing/Exporting
Configuration Data” in the User’s Guide.
2. Turn off the power.
3. Remove all USB devices such as USB keyboard and USB mouse from NSR-S20.
n
Remove all USB devices before performing the version upgrade. Otherwise, the version upgrade may
not be performed according to the procedure.
Procedure
1. Copy the five recovery files to the root folder of the USB flash memory.
2. Insert the USB flash memory into the USB connector on the NSR-S20.
3. Press the power switch on the NSR-S20 to turn on the power.
4. The device recognition LED on the USB flash memory lights about 20 seconds later and the USB
flash memory is recognized.
n
If the device recognition LED does not light, the USB flash memory may be an unsupported type.
Use another USB flash memory.
5. The NETWORK LED 1 and the NETWORK LED 2 on the NSR-S20 light.

1-9 (E)
NSR-S20
6. The NETWORK LED 1 and the NETWORK LED 2 go out after 30 seconds.
7. The NETWORK LED 2 lights first after about 90 seconds, and then the NETWORK LED 1 lights.
The version upgrade has been completed.
8. Disconnect the power cable of the NSR-S20, and then remove the USB flash memory.
n
Power cannot be turned off with the power switch on the NSR-S20 immediately after step 7 is com-
pleted. Unplug the power cable and then turn off the power.
9. Attach the USB devices (including USB keyboard and USB mouse) detached in Preparation 3.
10. Connect the power cable to the NSR-S20 and turn on the power.
11. Restore the configuration data stored in Preparation 1 in the NSR-S20.
n
For how to restore the configuration data in the NSR-S20, refer to “Importing/Exporting Configura-
tion Data” in the User’s Guide.
n
The record data storage destination has not been set after recovery. It is set by restoring the configura-
tion data.
When the configuration data is not restored, add the storage destination referring to “Adding a Stor-
age Location” in the User’s Guide.
Record data in the hard disk after recovery
Though the configuration data is initialized by the recovery of the unit, record data (including video,
audio, and operation log) in the hard disk is not initialized.
To initialize the record data in the hard disk, format the hard disk referring to “Preparation for Recording”
in the First Step Guide.
Even in the case of NSR-S20 failure, it is possible to play back and back up the record data by connecting
the hard disk to another NSR-S20 unit and registering it as a storage destination.

1-8. Notes on Repair Parts
1. Safety Related Components Warning
w
Components marked !are critical to safe operation. Therefore, specified parts should be used in the
case of replacement.
2. Standardization of Parts
Some repair parts supplied by Sony differ from those used for the unit. These are because of parts
commonality and improvement.
3. Stock of Parts
Parts marked with “o” at SP (Supply Code) column of the spare parts list may not be stocked. There-
fore, the delivery date will be delayed.
4. Harness
Harnesses with no part number are not registered as spare parts.
1-9. Lead-free Solder
Boards requiring use of lead-free solder are printed with a lead free mark (LF) indicating the solder
contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)
: LEAD FREE MARK
m
.Be sure to use the lead-free solder for the printed circuit board printed with the lead free mark.
.The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is
recommended to use the soldering iron having a temperature regulator.
.The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly
longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so
be careful.
