Handset Operational Warnings
Certain operational environments are potentially hazardous. Please read the following text care-
fully to ensure that you understand the handset’s operating conditions.
Potentially Explosive Atmospheres
Do not take your handset into any area with a potentially explosive atmosphere. Do not remove,
install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause
an explosion or fire resulting in bodily injury or even death.
Warning: Explosive Atmospheres
Avoid areas with potentially explosive atmospheres include fueling areas such as
lower decks on boats, fuel, or chemical transfer or storage facilities, areas where the
air contains chemicals or particles such as grain, dust, or metal powders, and any
other area where you would normally be advised to turn off your vehicle engine.
Areas with potentially explosive atmospheres are often marked with signs, but not
always.
