Transaction Memory may
actually be full. Enter PD command on data
terminal. Examine transaction
pointers and, if they are
reasonable, calculate the
number of transactions in the
memory. Could the memory
actually be full? If the memory is full, poll all
transactions and using the RP
command, move the
transaction pointer ahead.
Defective RAM chip Place the Series 1000 in
diagnostic mode. Run
diagnostic test 6. Does RAM
test fail? If RAM test fails, poll or print
all transactions and any other
important information and
replace the RAM chip.
*
Reload all system data.
If RAM test passes, poll or
print all transactions and any
other important information.
Using the RT and LN
commands, reset the
transaction file. Verify all other
system data and reload any
incorrect data
NOTE: If the memory was
recently reset for a similar
problem, contact GASBOY
Technical Service.
* Replacing a RAM removes all system information, requiring it to be reloaded. Printing and/or
polling all your transactions and system information will ensure that you enter the correct
information when you reload your system.
If you have software version 8.1 or higher or a FleetKey system, it contains two RAM chips, an
8K and a 32K. Replace the 32K RAM chip located in socket U23. Run diagnostic test 6. If it
fails again, replace the 8K RAM located in socket U22. Reload all system data.
