Areas with a potentially explosive atmosphere are often, but not
always, clearly marked. They include fueling areas, (such as gas
stations), below deck on boats, fuel or chemical transfer or storage
facilities, and areas where the air contains chemicals or particles
(such as grain, dust, or metal powders).
Do not transport or store flammable gas, liquid, or explosives in any
compartment of a vehicle which also contains the telephone and
accessories.
In the U.S., vehicles powered by liquid petroleum gas (such as
propane or butane) must comply with the National Fire Protection
Standard (NFPA-58). For a copy of this standard, contact the

Power supply
• Connect the AC power adapter of the charging unit only to the
designated power sources as marked on the charger.
• Make sure the cord is positioned so that it will not be subjected
to damage or stress.
• To reduce risk of electrical shock, unplug the chargers from any
power source before attempting to clean or move it.

main socket after charging.
