3.2.3 Concentration Alarm Menu

When the gas concentration exceeds the alarm threshold, the 
detector will give visual and audio alarms. The display will show 
real-time gas concentrations as seen in diagram 3-4.

3.2.4 Concentration Alarm Menu

A malfunction alarm will display if the laser reflection ratio is lower 
than the pre-set value. The display will tell you to change angle or 
measuring distance to obtain proper detection parameters.

3.2.5 Volume Setting Menu

In normal status, press the “+” button to increase volume and “–” 
button to decrease volume.

3.2.6 Alarm Threshold Setting Menu

Press the trigger to turn on detection status, then press the “+” or 
“–” button to increase or decrease the alarm threshold. The default 
value is set to 100.
