Perform the High-Speed Modem Transmit Test (refer to section 7.13). If this test fails, perform
replacements listed below until problem is corrected.

Data communication problems could have many different causes. It would be almost impossible to design
a RAP to cover all possible situations. Therefore, once you have performed the above listed steps, replace
the following assemblies in the order listed:

1) Modem board. (OKIFAX 2350/2450 only)
2) MCNT board.
3) NCU-U board.

Note:

This procedure determines the cause of a problem which occurs after the OKIFAX unit connects

with a remote station. Before troubleshooting any communication problems, run Self-Diagnosis, then verify
that the Flash ROM version is the most current version (in accordance with the Product Bulletins (formerly
known as Technical Service Bulletins [TSBs ). If the Flash ROM version is not the most current, replace
the MCNT board before proceeding!
