Update Transmitter Firmware
Update Firmware Code
Occasionally there are updates to the transmitter firmware. In addition, in
rare cases, you may experience problems with the firmware and may need to
download one or more of the files to the transmitter. See “Appendix 1:
ApexPro Troubleshooting” on page 76 to determine which file, if any, should
be downloaded.
The files that may be involved have these extensions:
 .app (Application firmware code – for transmitter operation)
 .mfg (Manufacturing firmware code – for programming the
transmitter)
 .tbl (IQ table – for modulation)
When updating the transmitter firmware, these files are installed in
C:\Program Files\GE Medical Systems\Apex and ApexPro Programming
Box Software, except if a different location is chosen. When downloading
specific files after experiencing problems, you will find the necessary files on
your hard drive where the firmware was installed.
