LD90 is a CLASS 1 Laser Product which is safe under reasonably foreseeable conditions of operation. DO NOT UNNECESSARILY LOOK INTO THE TRANSMITTER LENS! DO NOT UNNECESSARILY POINT THE TRANSMITTER LENS AT PEOPLES EYES! The invisible laser radiation INSIDE the instrument may exceed the accessible emission limits of laser class 1, thus never open the instrument's housing and never operate damaged instruments. Aligning the infrared laser instrument LD90 with the lenses of CCD-cameras or infrared night vision devices can result in damage to them. |

Data logging, storage and archiving
...
| Metadata (Metadata Plugin) |
|---|
|
During flight FGGALD90 data are stored within the rack unit. Analog data of the methane concentration are also stored within the aircraft onboard DMS system. |
Data archiving on land
| Metadata (Metadata Plugin) |
|---|
|
After the flight FGGA data have to be downloaded and LI-7200 are stored within the external devices fileland system of the aircraft data managment system (DMS). |
