Chapter 3 — Troubleshooting and Maintaining the SF51
Troubleshooting the Firmware Upgrade
If the SF51 locks up during the upgrade procedure and does not
respond when you press the Scan button or place it in a charger,
you may still be able to connect to it from your PC and upgrade
the firmware.
To troubleshoot a locked up SF51
1 Make sure that the SF51 is not seated in the 1-bay or 4-bay
charger.
2 From your PC, use the Bluetooth application to search for
Bluetooth devices.
3 If your SF51 appears in the list, connect to it from the
Bluetooth application.
If your SF51 does not appear in the list, contact Intermec
Support Services at 1-800-755-5505.
4 When the Bluetooth PIN Code Request box appears, enter
the following case-sensitive PIN in the Bluetooth PIN Code
field, and click OK:

The Bluetooth application connects to the boot loader code
on your SF51. "Intermec SF51 Boot Server" may appear in
the Device Name list instead of the name of your SF51
scanner.
5 Use your Bluetooth application to connect to the Intermec
SF51 Boot Server.
6 Start the SF51 Firmware Upgrade Utility.
7 Click Browse to browse to the location of the firmware (.ldr)
file. Select the firmware file and click Open.

port that the Intermec SF51 Boot Server is using for
