Warning and Notice 
Radio Frequency Interference 
General Statement on Interference 
Some electronic devices may be susceptible to electromagnetic interference. Locate the device away 
from TV set, radio and other electronic equipment to avoid electromagnetic interference. 
Medical Equipment 
  Switch off your wireless device when you are requested to do so in hospitals, clinics or 
healthcare facilities. These requests are designed to prevent possible interference with 
sensitive medical equipment. 
  Care must be taken when using your device in close proximity to personal medical devices, 
such as pacemakers and hearing aids. 
  Please consult your doctor and the medical device manufacturers to determine if the operation 
of the device may interfere with the operation of your medical devices. 
Explosive Environments 
  Do not use your device in dangerous environments such as petrol stations or chemical 
factories where there are explosive gases or explosive products being processed. In locations 
with potentially explosive atmospheres, obey all posted signs to turn off wireless devices. 
  Areas with potentially explosive atmospheres include fueling areas, below decks 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 store or transport the device in containers with flammable liquids, gases, or 
explosives. 
Product Handling 
  Please keep yourself at least 20 centimeters away from your device. 
  To avoid circuit malfunctions, do not use the device in dusty, damp or dirty environments or 
close to magnetic fields. 
  Before connecting or disconnecting the device cable, stop using the device and disconnect the 
power adapter. You should keep your hands dry during the operation. 
  When placing your device, keep it away from electrical appliances with strong magnetic or 
electric fields, such as microwave ovens and refrigerators. 
  Do not expose your device or its accessories to liquid, moisture or high humidity. Keep them in 
a well-ventilated and cool environment away from direct sunlight. 
  Keep your device or its accessories away from sources of heat and fire. High temperature can 
shorten the life of electronic devices.
