Radio Shack 20-163 User Manual

 

 

Upgrading your scanner is a quick, simple, and safe process. There is no way you can 
render your scanner inoperable by performing the firmware upgrade.   

Prepare for the upgrade by completing the following: 

1.  Download the 20-163/20-164 firmware upgrade package. 

2.  Install the drivers for the RadioShack Catalog #20-047 cable on your personal 

computer. 

3.  Connect the USB cable to an available USB port on your personal computer.   

4.  Know the COM port number that Windows has assigned to the USB cable. You can 

find the COM port number from Device Manager in Control Panel. 

1.  Upgrading your scanner will result in the loss of any programming that you have 

stored. We recommend that you save your work before proceeding with the upgrade 
using a third-party scanner programming software. For more information, see the 
“Setting the custom programmable trunking tables using third-party scanner 
programming software” section below.   

2.  There are two versions of CPU firmware:   

•  20-163_164_v106_BOOT100.EXE works with earlier versions that utilize Boot 

Version 1.00.   

•  20-163_164_v106_BOOT101.EXE works with more recent versions of that utilize 

Boot Version 1.01.   

To determine which version you should use, turn your radio off, hold down the PGM 
key, then turn the radio on again. Refer to the “uP Boot Ver:” line at the top of the 
display to determine the boot version used in your radio.   

3.  Double click on the correct upgrade file to start the upgrade process. Follow the on-

screen instructions exactly. 

4.  When the upgrade is complete, disconnect the USB cable from the scanner. Turn 

the scanner off, hold down the PGM key, then turn the scanner on again. Confirm 
that the radio now reports the CPU version as 1.06. Turn the radio off then on again 
to reset it.
