Turning the RMLD On
Depress the Power Switch located on the rear panel. When the unit first turns on, the
green Spotter laser will briefly flash, and the display will shortly show all of the icons.
The display will then return to its run display mode showing the ppm-m reading. The
Warning icon will also shortly display as the laser starts up. This warning should turn off
after a few seconds. The instrument will turn on with the same settings (e.g., Alarm
Detection Threshold, Spotter On, etc.) as when it was turned off.
**Note**
The Infrared detection laser is continuously on and the instrument is measuring the
methane concentration while the instrument is on.
