WARNING Do not look directly into the instrument transmitter or optics with magnifying optics (such as glasses, binoculars, and telescopes). Do not direct the beam into an area where such instruments are used. Viewing the laser output may pose an eye hazard.
WARNING Do not remove the ceilometer transmitter from its normal position without first switching off both the line and the battery power and detaching the transmitter ribbon cable from the Ceilometer Engine Board.
WARNING When operating the ceilometer, do not look at the ceilometer unit from the beam direction. When tilting the unit, make sure that it cannot be viewed from the beam direction with magnifying optics.
WARNING Only qualified maintenance personnel may perform maintenance procedures. Make sure unauthorized persons cannot access the work area during service operations.
WARNING After disconnecting the power cable, dangerous voltages can exist for some time. To avoid injury, disconnect the power and discharge circuits before touching them.
WARNING Always consult local authorities on decisions that relate to aviation safety, grounding, lightning protection, safe installation, and power supply. Follow local and state legislation and regulations.
WARNING Do not service the system alone. Do not reach into parts and assemblies that are AC (mains) powered and live except in the presence of someone who can provide first aid.
WARNING Do not substitute parts or modify the system, or install unsuitable parts in the system. Improper modification can damage the product or lead to malfunction.
WARNING Do not perform maintenance procedures when the wind speed is more than 25 m/s (55 mph).
WARNING Do not perform installation or maintenance procedures when there is a risk of thunderstorm or lightning activity in the area.
WARNING Do not operate in an explosive atmosphere, for example, when flammable gases or fumes are present. Operation of electrical equipment in such an environment constitutes a safety hazard.
WARNING Do not replace components when the system is powered up. Disconnect all power sources before performing maintenance procedures.
WARNING Do not open the power supply unit. There are no user-serviceable parts inside the unit. If the power supply unit is faulty, replace it.
WARNING Failure to comply with these precautions or with specific warnings elsewhere in these instructions violates safety standards of design, manufacture, and intended use of the product. Vaisala assumes no liability for the customer's failure to comply with these requirements.
WARNING Follow local and state legislation and regulations on occupational safety.
WARNING Keep away from live circuits. Operating personnel must observe safety regulations at all times.
WARNING Make sure that you prepare or connect only de-energized wires.

CAUTION Always use the specified cables. The wrong type of cable can damage sensors or the system.
CAUTION Do not damage or change the wiring. Incorrect wiring can cause damage and prevent or limit operation.
CAUTION Make sure that the grounding wire is longer than the phase and neutral wires. Under mechanical stress, the grounding wire must be the last to disconnect from the protective ground terminal.
CAUTION Improper modification can damage the product or lead to malfunction. Any modification voids your warranty.
CAUTION To maximize performance, complete the maintenance tasks according to the recommended schedule.
