Radio Shack 20-163 - Manual (Page 3)

PRO-163/PRO-164
CPU 1.07 Firmware Upgrade
Troubleshooting
• Ensure that the USB cable drivers are installed and that Windows recognizes the
cable and has assigned a COM port number.
• Ensure that the correct COM port is set in the upgrader.
• Ensure that no other applications are running that access the same COM port.
• Repeat the upgrade process, making certain that the on-screen instructions of the
upgrader are followed exactly.
If the above suggestions do not work, try running the upgrade utility on a different
computer. In some cases hidden applications can cause port conflicts. It is not always
possible to see these hidden applications and disable them to eliminate the conflict.
