Adjusting display brilliance
The brilliance is adjusted from the Brilliance pop-up.
• Display the pop-up by pressing the Standby/Brilliance key, then adjust the display
brilliance by turning the rotary knob.
At first start-up, the display brilliance is set to 100%. When the unit is restarted, the brilliance

The system includes a Day and a Night color palette. When the brilliance is set to 40% or

You close the pop-up by pressing the Exit key.
Acknowledging alerts
The Alerts softkey is labelled Alerts Acknowledge (Alerts Ack on smaller screens) if there is an
unacknowledged alarm or warning in the system.
Acknowledge the most recent alert by pressing the Alerts softkey.
• Repeat pressing this softkey to continue to acknowledge alerts from the top of the Alerts
panel.
• Press the Exit key to exit the Alerts panel.
When an alert is acknowledged, the alert icon stops flashing and changes to the
acknowledged icon. The siren continues to sound if there are remaining unacknowledged
alerts, otherwise it is muted.
The acknowledged alert is not moved to its new position in the sort order until there has
been 2 seconds without any alerts being acknowledged.
