CHAPTER 3 TROUBLESHOOTING
4.3 Recording the Sound of the Communications Procedure
If the Service Manual for the host machine instructs you to "record the sound of the
communications procedure on a DAT or MD, ask the Technical Center for analysis," refer
to the following (for a common way of connection):
DAT recorder
MD recorder
Use standard mode (SP) as the recoding mode.
Set the recoding level so that the sound of
communication may be clearly heard while it is free of noise.
5 Upgrading
For descriptions of how to upgrade the board, see Chapter 14 of the Service Manual for
the host machine.
