5.8 Alerts
—The <Alert> menu
Alerts represent exception conditions. An Alert condition
may be presently active, or it may have been active at some
earlier time. When an Alert occurs, the MJ-5 stores it in the
<
ALERT > menu, and illuminates the Alert LED Indicator.
5.8.1 Viewing Alerts
If the Alert indicator is flashing, it denotes that an Alert has
occurred. Use either the Alert fast path key or the menu and
Scroll keys to view the <Alert> menu. Use the down arrow
key to scroll through the Alerts.
Table 5.8
Alert Data Items
If the Alert name is flashing, acknowledgment is required.
5.8.2 Acknowledging an Alert
To acknowledge the Alert, press the Cancel/Reset key. If
the Alert condition is still active, the Alert name will stop
flashing but the Alert indicator will remain on (steady) until
the condition clears. If multiple Alerts have occurred, you
can step through them, one at a time using the Alert key or
the ▲ and ▼ keys. The Alert indicator will continue
to
flash until all Alerts have been acknowledged.
The conditions listed in Table 5.8 activate ALERT status.
The conditions are listed in priority sequence from highest
priority at the top to lowest priority at the bottom.
Notes for Table 5.8:
1. Alert status is in effect if any Message condition is active. If the Alert status is the result of more than one condition, the Message Indicator
will flash until all Alerts requiring acknowledgment have been acknowledged. Whenever the Alert Indicator is flashing, it is an indication
that the contents of the <
ALERT > menu should be reviewed.
2. Continuous - Condition lasts indefinitely (may persist after Alert is acknowledged).
3. Momentary - Condition lasts briefly.
4. ACK required - The MJ-5 keeps the Alert active until you acknowledge it.
5. Auto-clear - The MJ-5 automatically clears the Alert when the condition ceases.
6.
The Tap Track Error alert can be disabled, if desired. See Table 4.2 on page 17.
