RBS 2109 User’s Guide Warning! In the event of a fire, evacuate the building or equipment site and raise the fire alarm at the closest alarm point, or call the emergency number. Do not re-enter a burning building under any circumstances. Warning! Heater in operation. Do not block the heater vents or place combustible materials close to the unit, as this can cause a fire that can endanger life. 2.6.
RBS 2109 User’s Guide Caution! Parts inside this equipment attain high temperatures during normal operation, which can cause burns to the skin if touched without heat protective clothing. Always use heat protective clothing when working with equipment containing hot surfaces, or switch the equipment off and allow it to cool before starting work. Caution! A heater, producing hot air, is in use in this equipment. Direct contact with hot air can lead to burns.
RBS 2109 User’s Guide 2.9 Radio Frequency Exposure Hazards This section provides instructions and information on potential hazards related to radio frequency (RF) electromagnetic field (EMF) exposure from fixed radio transmitters (as opposed to mobile phones). 2.9.1 General RF Safety Information Caution! Excessive RF exposure can result in potentially adverse health effects.
RBS 2109 User’s Guide Caution! Always be aware of other RF transmission antennas located close to the antenna you will be working with. If the RF exposure level is unknown, contact the equipment operator or ensure that measurements are done to verify that levels are below specified safety limits before starting work. Caution! Broken or disconnected RF cables can lead to exposure levels reaching, or exceeding, specified safety limits. Repair or reconnect cables before starting work. Note: 2.
RBS 2109 User’s Guide Danger! Never look directly into the end of a fiber optic cable, or other laser source. Equipment that transmits laser light can cause permanent eye damage. Switch off the laser before starting work on laser equipment. Safety Precautions for Working with Class 3 Laser The following precautions must be observed when working with products containing a Class 3 laser hazard symbol: 2.11 • Never look into the light emitting end of a functioning optical fibre.
RBS 2109 User’s Guide Danger! This product contains Beryllium Oxide (BeO), which can cause injury to skin or mucous membranes severe enough to endanger life or cause permanent injury. BeO dust is created by chafing, filing, or breakage and is extremely dangerous if inhaled, even for only a few seconds. Particles penetrating the skin through wounds or abrasions are liable to cause chronic ulcerations. Do not handle components containing BeO without protection.
RBS 2109 User’s Guide Caution! Excessive heat can cause battery casing to soften and warp, potentially allowing acid to escape. In contact with the skin, acid can cause injury, and if breathed in, can affect the airways. Use protective equipment when replacing batteries. Caution! Batteries can leak electrolyte if improperly handled. Electrolyte in contact with skin or eyes can cause injury. In the event of electrolyte injuries, rinse the affected area with water and seek medical attention immediately.
