An example of a Stored Events screen is shown here. Use the   arrow keys to select the

6.2.3.2.1 (Monitor: Stored-Events) Event ###

The event log can store up to 255 events. Use the  arrow keys to scroll from Event 001 to

Event 255. When an event occurs, the modem time- and date-stamps the fault and stores it in

the event log. Similarly, when the fault condition clears, the modem records this as well.

Note that, in accordance with European convention, the log shows the date in DAY-MONTH-

YEAR format and displays the time in military (24-hour) format.

The Stored Event reporting format follows the same symbol indications and meaning as

explained in Sect. 6.2.3.1 (Monitor:) Live-Alarms → Unit, Transmit, or Receive.

Press ENTER or CLEAR to return to the previous menu.
