Communication error

Communication errors may occur when the condition of a particular phone circuit happens to be bad at
the time of attempting the communication job. Therefore, do the communication over again. If commu-
nication errors occur too many times, prepare another (operational) FAX unit and check the communi-
cation condition among the three FAX units, thus analyzing the troubles.
1) If normal communications are possible between A and C, and the communication trouble occurs B
and C, it can be assumed that FAX B is malfunctioning.
2) If normal communications are possible between B and C, and the communication trouble occurs A
and C, it can be assumed that FAX A is malfunctioning. Therefore, adjust the transmission attenua-
tor value (13-325, 13-430, 13-567, 13-616) and the cable equalizer value (13-328, 13-433).
3) If normal communications are possible between A and C and between B and C, it can be assumed
that there is a problem in the line between A and B.
