TROUBLESHOOTING AND ALARM SYSTEM
Overview of Alarms
This device contains an alarm system which monitors the state of the device and alerts of abnormal operation, loss of essential performance or failures. Alarm
conditions are shown on the LCD display. The alarm system functions are tested at power up by lighting all visual alarm indicators and sounding the audible
alarm (beep). All alarms are Low Priority Technical Alarms.
To mute the Audible Alarm, press and release power button. The Alarm Silenced symbol will appear on the display until the alarm condition is corrected.
