Operating environment for using wireless function 
(Optional)
Warning! For safety reasons, turn off all wireless or radio transmitting 
devices when using your machine under the following conditions. These 
devices may include, but are not limited to: wireless LAN (WLAN), Bluetooth 
and/or 3G.
Remember to follow any special regulations in force in any area, and always 
switch off your device when its use is prohibited or when it may cause 
interference or danger. Use the device only in its normal operating positions. 
This device meets RF exposure guidelines when used normally, and it and its 
antenna are positioned at least 1.5 centimeters (5/8 inches) away from your 
body. It should not contain metal and you should position the device the above-
stated distance from your body. 
To successfully transmit data files or messages, this device requires a good 
quality connection to the network. In some cases, transmission of data files or 
messages may be delayed until such a connection is available. 
Ensure that the above separation distance instructions are followed until the 
transmission is completed. 
Parts of the device are magnetic. Metallic materials may be attracted to the 
device, and persons with hearing aids should not hold the device to the ear with 
the hearing aid. Do not place credit cards or other magnetic storage media near 
the device, because information stored on them may be erased.
Medical devices
Operation of any radio transmitting equipment, including wireless phones, may 
interfere with the functionality of inadequately protected medical devices. 
Consult a physician or the manufacturer of the medical device to determine if 
they are adequately shielded from external RF energy or if you have any 
questions. Switch off your device in health care facilities when any regulations 
posted in these areas instruct you to do so. Hospitals or health care facilities 
may be using equipment that could be sensitive to external RF transmissions.
Pacemakers. Pacemaker manufacturers recommend that a minimum separation 
of 15.3 centimeters (6 inches) be maintained between wireless devices and a 
pacemaker to avoid potential interference with the pacemaker. These 
recommendations are consistent with the independent research by and 
recommendations of Wireless Technology Research. Persons with pacemakers 
should do the following:
•Always keep the device more than 15.3 centimeters (6 inches) from the 
pacemaker.
•Not carry the device near your pacemaker when the device is switched on. 
If you suspect interference, switch off your device, and move it. 
						

							viii
Hearing aids. Some digital wireless devices may interfere with some hearing 
aids. If interference occurs, consult your service provider.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic 
systems in motor vehicles such as electronic fuel injection systems, electronic 
antiskid (antilock) braking systems, electronic speed control systems, and air bag 
systems. For more information, check with the manufacturer, or its 
representative, of your vehicle or any equipment that has been added. Only 
qualified personnel should service the device, or install the device in a vehicle. 
Faulty installation or service may be dangerous and may invalidate any 
warranty that may apply to the device. Check regularly that all wireless 
equipment in your vehicle is mounted and operating properly. Do not store or 
carry flammable liquids, gases, or explosive materials in the same compartment 
as the device, its parts, or enhancements. For vehicles equipped with an air bag, 
remember that air bags inflate with great force. Do not place objects, including 
installed or portable wireless equipment in the area over the air bag or in the 
air bag deployment area. If in-vehicle wireless equipment is improperly 
installed, and the air bag inflates, serious injury could result. 
Using your device while flying in aircraft is prohibited. Switch off your device 
before boarding an aircraft. The use of wireless teledevices in an aircraft may be 
dangerous to the operation of the aircraft, disrupt the wireless telephone 
network, and may be illegal.
Potentially explosive environments
Switch off your device when in any area with a potentially explosive 
atmosphere and obey all signs and instructions. Potentially explosive 
atmospheres include areas where you would normally be advised to turn off 
your vehicle engine. Sparks in such areas could cause an explosion or fire 
resulting in bodily injury or even death. Switch off the device at refueling points 
such as near gas pumps at service stations. Observe restrictions on the use of 
radio equipment in fuel depots, storage, and distribution areas; chemical plants; 
or where blasting operations are in progress. Areas with a potentially explosive 
atmosphere are often, but not always, clearly marked. They include below deck 
on boats, chemical transfer or storage facilities, vehicles using liquefied 
petroleum gas (such as propane or butane), and areas where the air contains 
chemicals or particles such as grain, dust or metal powders.
Caution for Listening
To protect your hearing, follow these instructions.
•Increase the volume gradually until you can hear clearly and comfortably.
•Do not increase the volume level after your ears have adjusted.
•Do not listen to music at high volumes for extended periods.•Do not increase the volume to block out noisy surroundings.
