Problem
HFA2i instruments with the new CPU (P/N 55392), using application revision 3.4 software, may fail to
reach the main menu on startup. The display will be blank and the instrument will give no indication that a
failure has occurred.
Cause
Failures in the initialization of the RAM disk are one possible source for the blank display on startup.
Solution
Changes have been made to the application software in release 3.4.5. Load the application software
revision 3.4.5 to install the new RAM disk initialization routine and eliminate the start up problem. If the
software upgrade does not correct the start up problem, use the techniques found in the HFA2i service
manual to troubleshoot and repair the unit.
Instruments that have been manufactured with the new CPU and software revision 3.4, and require the
3.4.5 software, are in the following serial number ranges:
720i-5815 through 720i-5838
740i-11330 through 740i-11446
745i-4546 through 745i-4559
750i-9376 through 750i-9393
