Record

Record is a troubleshooting tool used by the end user in

conjunction with support personnel. This function allows
the end user to retrieve and report any sequence faults to
support personnel. A sequence fault is an irregular or
unexpected event.

There are two selections under Record: Display and

Clear. Display allows up to eight sequence fault messages
that have been recorded by the modem to be displayed on
the LCD. If no sequence faults have occurred, then
Modem O.K. appears.

Clear is used to remove all sequence fault messages

from nonvolatile memory and the LCD.
