Cause
These events are indicative of a modem that is starting to fail.
Resolution
The events typically are nothing to worry about until they start to appear frequently as shown in the above screenshot.
If there are only one or two occurrences of this modem error, the meter can be left alone. If, however, there are multiple events, the solution would be either to RMA the meter or purchase a new COMM Card. The COMM Card can be bought separately and installed in the field.
