Silencing an alarm ( )
You can silence an alarm by pressing the Alarm Silence/Indicator ( ) button. This will silence the alarm for one
minute. If another alarm occurs while the silence period is active, the audible alarm portion of the new alarm will
not sound until the silence period expires. When the silence period expires, the alarm’s audible alarm is reactivated.
Touching the Alarm Silence/Indicator button while the silence period is active will restart the silence period.
alarm Message Screens
When an alarm message is activated, an alarm screen is displayed, showing the text or icon specific to the most
recent, highest priority alarm.
Pressing the control wheel will reset the alarm and remove the alarm screen from the display. Resetting the alarm
allows you to return to the previous screen. If multiple alarms occur during the same period of time, the alarm screen
will display the higher priority alarm (higher priority alarms take precedence over lower priority alarms).
