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 facilities, and areas where the air con-
tains 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.
Traffic Security
• Do not use your device while driving, and observe the local laws and regulations.
• Do not use your device while flying in an aircraft. Power off your device before boarding
an aircraft. Using wireless devices in an aircraft may cause danger to the operation of the
aircraft and disrupt the wireless telephone network. It may also be considered illegal.
Operating Environment
• Do not use or charge the device in dusty, damp, and dirty places or places with magnetic
fields. Otherwise, it may result in a malfunction of the circuit.
• On a stormy day with thunder, do not use your device, to prevent any danger caused by
lightning.
• When you are on a call, do not touch the antenna. Touching the antenna affects the call
quality and results in increase in power consumption. As a result, the talk time and the
standby time are reduced.
