Warnings and Precautions

Potentially Explosive Atmosphere

Power off your device in any area with a potentially explosive atmosphere,
and comply with all signs and instructions. Areas that may have potentially
explosive atmospheres include the areas where you would normally be
advised to turn off your vehicle engine. Triggering of sparks in such areas
could cause an explosion or a fire, resulting in bodily injuries or even
deaths. Do not power on your device at refueling points such as service
stations. Comply with restrictions on the use of radio equipment in fuel
depots, storage, and distribution areas, and chemical plants. In addition,
adhere to restrictions in areas where blasting operations are in progress.
Before using the device, watch out for areas that have potentially explosive
atmospheres that are often, but not always, clearly marked. Such locations
include areas below the deck on boats, chemical transfer or storage facil-
ities, and areas where the air contains chemicals or particles such as grain,
dust, or metal powders. Ask the manufacturers of vehicles using liquefied
petroleum gas (such as propane or butane) whether this device can be
safely used in their vicinity.
