Alarms

The Current Alarms screen (see Fig. 12 on p. 19) allows you to set High or Low alarms for the
CO

gas channel and, if this option is present, the O

2

gas channel. The alarms for each channel

can be enabled or disabled independently in this screen.
Once enabled, these alarms become active in the Main screen; this is indicated by a bell icon.
If an alarm is triggered, the screen turns red and displays a flashing bell

icon. The audible

alarm, a beeper, sounds until the gas level has recovered beyond the set-point.
High alarms are triggered when the gas level exceeds the maximum value you set, while Low
alarms are triggered when the gas level falls below the minimum value you set.
To access the Current Alarms screen from the Main screen:

1. Press the Menu key on the instrument panel.
2. Press numeric key 2 to display the Utilities Menu.
3. Press numeric key 3 to display the Current Alarms screen:
